C1.3 Determine pattern rules and use them to extend patterns, make and justify predictions, and identify missing elements in patterns.
Activity 1: Find the Missing Term
Ask students to observe the following repeating pattern.
Ask the following questions:
- What is the element in the Position 4? How do you know?
- What is the element in the Position 9? How do you know?
- What would be the element in the Position 12?
Encourage students to describe the basic pattern as well as the attributes.
