Card Sort: Situations, Equations, and Diagrams

Your teacher will give you a set of cards showing situations, equations, and diagrams.

Sort the cards into groups so that the cards in each group represent the same situation. Be ready to explain your reasoning.

Makes Sense to Me: A Gallery Walk

Your teacher will assign a problem to your group. Work together to solve your assigned problem.

As you visit other groups' posters, consider how each answer makes sense.

Cool Down: Equation Match

Andre had 451 beads. 125 beads were blue. 223 beads were pink. The rest of the beads were yellow. How many beads were yellow?
Which equation matches this situation?

451 + 125 + 223 = ?

? + 125 + 223 = 451

? = 451 + 125 - 223
