B1.6 describe relationships and show equivalences among fractions and decimal numbers up to thousandths, using appropriate tools and drawings, in various contexts
Activity 1: Clothesline
Write fractions, mixed numbers, whole numbers, and decimal numbers on flash cards. Place two cards on a clothesline (or number line). Have a student randomly select a flash card and place it on the clothesline (or number line), paying attention to the order and space between the numbers. When the student places their card, they must justify their choice of location and answer any questions that may be asked. Continue the activity by inviting other students to take turns doing the same thing.
