Students will be able to use mental math to add and subtract.

Paper & Pencil

Flashcards for race game

I will challenge two students to solve the same math problem.  I will ask the one to solve it mentally and the other using pencil and paper.

1. I will begin by explaining how we can add or subtract numbers easier by using two techniques.

2. I will introduce the terms break apart and compensation.

3. I will ask students if they have any techniques they use to help them mentally add or subtract numbers.

4. Next, we will go over several examples together using break apart and compensation.

5. I will have students try various problems and choose their method; break apart, compensation, or paper and pencil. 

6. Finally, to reinforce using mental math we will play the race game.

The students will create a problem and have their neighbor try to solve it mentally.
