For online/hybrid learning, small groups could be set up ahead of time. This could be facilitated via breakout rooms, depending on the different district conferencing tools used. In the breakout rooms, students could work together to generate questions and make assumptions. They could use a virtual whiteboard to support their discussions, such as shared slides, Google Jamboard, Microsoft Whiteboard, Padlet depending on district tools (recording tool). This will also create a record of their work in order to communicate clearly with each other and the teacher. For virtual manipulatives, students can use the mathies website.

If students need to collect data (for example, to time the time it takes for someone to wash their hands), they could do this at home with family members).

Upload copies of Appendix 1 and Appendix 2 ahead of time in your virtual learning environment (for example, Microsoft Teams, Google Classroom, D2L).

Learning and Teaching Activities

Understand the Situation

Student Moves	Teacher Moves
Students will generate questions about the situation that need answering. Students may generate questions as a whole class or as small groups of 3 - 4 students, then share, round-robin style, until all questions have been captured by the teacher. Use virtual breakout rooms and the recording tool.	The teacher will present the situation: In the late 1980's there was a film about a high-school student who has an uncanny skill at skipping classes and getting away with it. Intending to make one last duck-out before graduation he calls in sick, “borrows” a Ferrari, and embarks on a one-day journey through the streets of Chicago. On his trail is high school principal Rooney, who is determined to catch him in the act. (Google synopsis). The teacher will explain to students that in its day, this was a very popular movie and ask students to consider why it might have been so popular and to share their ideas.The teacher will explain that while our movie hero might have skipped school, there are many reasons students are absent from school. The teacher will ask students to identify some reasons they and other students might be absent from school and note the ideas on the board. The teacher will ask students to estimate the percentage of absences related to common contagious illnesses and explain that the incidence of these types of illnesses can be reduced through frequent and proper hand cleaning. The teacher will provide students with a copy of “Show Me the Science - Why Wash Your Hands?” and allow students time to read. The teacher will explain to students that schools are always looking to improve student health and learning. Preventing the spread of illnesses such as the cold and flu will keep kids and their families healthier and improve learning outcomes since absences will be reduced. The teacher will explain to students a school board is considering mandating scheduled hand cleaning several times a day. In order to better understand the impact of this policy, it wants to determine what percentage of instructional time would be lost due to this schedule. The teacher will capture student questions and listen for assumptions and misconceptions about the situation.
Opportunities for Differentiation Task could be simplified by asking students to create a model that predicts the time it takes for a class to wash their hands. Opportunities for Assessment (Observation and Conversation) Students are able to generate questions. Students identify and justify their assumptions.

Analyse the Situation

Student Moves	Teacher Moves
With the teacher’s guidance, students will narrow down the initial list of questions. Use the recording tool to narrow down the list of questions. Of the questions that remain, students will brainstorm what information they have and what information they would need to be able to answer these questions.	The teacher will guide students in narrowing down the list of questions: Are some questions the same? Do some questions already have known answers? The teacher will help the students cull the list of questions so that only a few remain. For example: How much time does it take for one class to wash their hands? How much instructional time is there in a day? How many times should a class wash their hands in a day? The teacher will guide students in recognizing the many ways that mathematics can be used to enable us to better understand the situation. Can mathematics be used to gather information that we need? Can mathematics be used to analyse the information we have gathered? What quantities or measurements are required to answer the question? What quantities or measurements do we know? Which quantities or measurements will always stay the same (constant/invariant)? Which quantities or measurements could change (variable)? Can these take on any value, or is there a range of acceptable/realistic values within which these quantities or measurements must lie (constraints)? How could we get information about the quantities/measurements we don't know? Will we have to make any assumptions in order to proceed? For example: I assume it will take _ min. per student to wash their hands. I assume it would be better if we weren't all in a line. I assume that there will need to be some time between each student. I assume that students need to use a sink and not just hand sanitizer. I assume no instruction happens as students are washing hands.

Create a Mathematical Model

Student Moves	Teacher Moves
Students will use mathematical tools to develop a plan to minimize classroom interruptions, while allowing ample time for each student to wash their hands. They will record all assumptions they are making. They will record all new information they have gathered and how they acquired that information. Students will mathematically justify all estimations and numerical values (either given, researched, or calculated) in their plan. Students' models will be useful to plan for minimized disruptions and predict how long these disruptions will take.	The teacher will look for any misconceptions. They will decide if any are common enough to call to the attention of the entire class, or they can be addressed individually or within the group. The teacher will look out for students who really need to revisit “understand the problem” or “analyse the situation” (Are students struggling with creating a plan because there is something about the situation that they do not fully understand? Are they struggling because they need to make an assumption to narrow down the problem? Did they make an unnecessary assumption that is preventing them from making a fulsome model?) The teacher will decide when would be a good time to have the groups share their progress. Examples of natural checkpoints Students have gathered data. Students have organized data. Students have created a first mathematical model. Use multiple rooms in your videoconferencing tool to have groups share their progress. As groups share their progress, the teacher will question students to help them to reflect on their strengths and their emotions. For example: What feelings came up as you were building your model? How did they change over time? What strength does each group member apply to the process? How did this help you to reach your objective? What was the most interesting part of the modelling process so far? Why?
Opportunities for Differentiation Students may observe someone or a class washing their hands before creating the model. Assist students in organizing their information, providing appropriate strategies or graphic organizers as necessary. Provide direct instruction, as necessary, on: Writing equations Using variables Calculating measures of central tendency Opportunities for Assessment (Observation and Conversation) Students effectively create a model by identifying needed information, using effective strategies and appropriate tools and making links to other situations and other math concepts. Students communicate their ideas and their reasoning clearly, using appropriate vocabulary. Students apply the following, as necessary and appropriate for their model: use the order of operations and the relationships between operations to solve problems including whole numbers, decimal numbers and percentages. solve equations that involve multiple terms. collect qualitative data and discrete and continuous quantitative data to answer questions of interest, and organize the sets of data.

Further Consolidation – Next Steps for Students and Teachers

Students may be given the opportunity to revise their mathematical models after the whole class has completed their presentations and feedback has been shared.

If possible, the teacher will allow students to repeat the “predict and verify” process with other classes in the school.

Students collect and share the data needed to make a prediction using their model (ex., the number of students in the class, the distance from the washroom, etc.)
Students use the data to make predictions based on their model.
Students (individually, as a small group or whole class) observe the class washing their hands, note their observations and time the experience.
Students share data as necessary.
Students compare their predicted time to the actual time.
As a group, students discuss the accuracy of their models. Allow students to continue to modify their models based on new information.

Understand the Situation

Student Moves	Teacher Moves
Within the context of their learning in geography about natural resources and the ways in which people extract and use forestry products, the teacher will pose the following problem: At the current rate of deforestation in Canada, at what point will we no longer have enough forestry products to meet our needs? Students will be placed in small flexible groups and given the task of trying to figure out what they need to know in order to solve this problem. The teacher consolidates the students’ ideas into a larger list of what they might need to know in order to solve this problem. Anticipated responses include: How many hectares of trees do we have?

Within the context of their learning in geography about natural resources and the ways in which people extract and use forestry products, the teacher will pose the following problem:

At the current rate of deforestation in Canada, at what point will we no longer have enough forestry products to meet our needs?

Students will be placed in small flexible groups and given the task of trying to figure out what they need to know in order to solve this problem.

The teacher consolidates the students’ ideas into a larger list of what they might need to know in order to solve this problem. Anticipated responses include:

How many hectares of trees do we have?
How much lumber do we harvest per year?
Is the amount of lumber we harvest increasing or holding steady?
Are there places in Canada where we cannot harvest trees?
How many hectares of trees are lost each year due to forest fires?
What is the reforestation rate?

Analyse the Situation

Student Moves	Teacher Moves
Students return to their small groups with the list generated by the whole class and are given the following task: Determine which of the questions can be researched. Identify which of the questions would be most useful in helping to solve the problem. Order your list of questions according to their usefulness in solving the problem, in order to allow for focused and timely research. Once each group has generated and prioritized their list of questions, they are given multiple periods, either during math or geography, or both, to research and gather the data to answer their questions. Canadian Forest Service Statistical Data	The teacher moves about the room to support each small group in identifying which questions are the most useful for solving the problem. The teacher might ask: Which of these questions do you need answered in order to find the point at which our supply of forestry products will not be able to meet our demand? Which of these answers would be the most helpful in solving this problem? Which of these questions will best help you determine how our needs of forestry products might change over time? Which questions might be most effective in helping you determine how accessible forestry products will be over time? The teacher will also help students determine how they could research to find the required data. The teacher might ask: Where could you find the answers to these questions? How will you know your information is reliable? During the research periods, it is important that the teacher is conferencing with and checking-in on each group frequently in order to ensure that their research is focused and that the data they are gathering is relevant and reliable. The teacher circulates to observe the groups and guide them in reflecting on their data for the purpose of determining which data they are going to use to make their model. The teacher helps the students identify which data is not helpful for solving the problem and guides them in removing extraneous information in order to make their model more manageable. The teacher might ask: Which information does not help us determine when our need for forestry products will overtake our supply? Which information can help us answer this question? What quantities or measurements are remaining constant? Which quantities are changing? What is the rate at which they are changing? How do these quantities or rates of change help us determine a point at which our supply of forestry products will be overtaken by our need for these products? Ultimately, the teacher poses the following question to each group: How can we use mathematics and the data you have gathered to find the point at which we will no longer have enough forestry products in Canada to meet our needs? How can we use a graphic to determine when the demand will overtake the supply?

The students work in their groups to create a model using their data that will determine when the demand for Canadian forestry products will overtake the available supply. Students’ choice of graphic representations may include: a number line; a double-bar graph; a double-line graph; an equation.	The teacher moves about the room to observe and guide small group discussions through questioning: Which graphic representation have you selected for your model? How could you visually represent any equations you have created? Have you accounted for any rates that may change over time? (e.g. an increasing population would account for an increase in the demand for forestry products; increasing wildfire rates would have an impact on the available supply).

Analyse and Assess the Model

Student Moves	Teacher Moves
In their small groups or individually in their Math Journal, the students will reflect on their models and the assumptions they made when creating their models. They will reflect on the following questions: Does their model provide a point at which the demand for Canadian forestry products will no longer meet our needs? Is the point in time identified by their model reasonable? Could their model be applied to the issue of extraction / harvesting of other natural resources? Why or why not? The teacher will select certain groups or individual students to share portions of their reflections with the whole group in order to move the learning forward. For instance, the teacher will have different groups present the year that their models generated in order to demonstrate and debrief the impact of different assumptions on the specific years generated by the models. In particular, the teacher will select groups to share their models in order to demonstrate the impact that realistic assumptions, such as the increased rate of wildfires or population growth, would have on the year(s) identified as the point at which the available forestry products would no longer meet the need for such products.	The teacher moves about the room to observe and guide the students’ reflections through questioning: Which of your assumptions were correct? Which of your assumptions had the biggest impact on your model? Did you recognize the fact that rates will change over time? (e.g. increasing population will impact the rate at which forestry products are used; as a natural resource becomes more limited, the rate of usage changes as people find alternative sources or the cost of the resource increases, etc.) What impact did/would these changed rates have on the point in time generated by your model? What were the most important factors that led to your choice of year?

Consolidation of Learning

Student Moves	Teacher Moves
The students present their models and explain how they used mathematics to determine a year in response to the problem. As these models would be generating predictive data, the students would be unable to test them. The teacher would lead a class discussion on what students might see happening in the real world that would lead to the need to readjust their models. For example, if the Canadian government imposed a tax on the use of forestry products or the rate of wildfires increased at an unprecedented rate, the models would have to be adjusted to account for these factors. As a class, the students reflect on which model they think best represents what would actually happen. In their small groups or as a whole class, the students reflect on the process of mathematical learning, why we engage in mathematical modelling and what they learned about themselves as mathematicians and about the issue of deforestation.	The teacher helps students see the commonalities amongst the various groups’ models through questioning: What similarities did we see between the different models? What differences did we see between the models? What impact did different assumptions have on the years that were generated by the models? Which model do you think most closely represents the modelling that would take place in real life? Why? How can you tell? The teacher helps students reflect on the process of mathematical modelling by posing reflective questions such as: Why do we use mathematical modelling? How does mathematical modelling help us understand issues or solve problems? What was the benefit of having each group share their models and their reflections? What challenges did you face throughout the process? How did you respond to these challenges? What different approaches did you try throughout the process? Which ones were the most effective? Why?
