Joyce reads a subtraction word problem to the class and her students (disguised with animal masks) act out the problem. The class then discusses the problem, its meaning, and how to solve it. Joyce continues this routine until all students have had a chance to act out a problem.

Strategy Implementation Questions

Questions to think about when implementing the strategy

- How would you modify this strategy for the students in your classroom?
- What might be challenging for students about this strategy?
- What routines could you implement to make this strategy a success?
- How could acting out problems support students to make meaning of the problem?

Lesson Notes

I tell the students that we are going to take away problems. I pass out the masks to the students and then I call different combinations of animals in front of the class. I count off a group of four students to go to the front of the room. I say to the students, "There are 4 animals in the barnyard. Gordy invites 2 cows to come to his party in the barn. How many animals are left?" I have the cows step off to the side. I call on a student to answer the question. I then invite the class to say the number sentence with me, "4 take away 2 is 2."
