1st Grade Math

Positive: I will model subtraction with manipulatives in this lesson. The students are familiar with using manipulatives in addition.
Near: Visualizing what subtraction means by using the manipulatives gives the students a better understanding.
Far: Since the students have already mastered using the manipulatives in math and are now mastering using them in subtraction, they will have an easier time as their math skills develop further.
Negative: The more the students practice, the better they will get at mastering their skills. Eventually they will be able to solve these problems without manipulatives.
