Review:

In the past we've gone over what adding 1 or taking away 1 looks like.



Show me what + 1 looks like. (have students do problems on white board or with rolling chairs)



Let's practice taking away or "minus 1".





Now let's practice counting to 20. Ready?



Today and for the rest of the month we are going to practice adding and subtract. In the past we've working with smaller numbers like 1 and 2. Now we are going to work with some BIG numbers...like we are going to add up to 20!!

Before we get started, here are 2 different tricks that you can use to help you.

1) You can count using your hand (show how, start with #, then count on fingers)

2) You can also use the number line of your desks.

Part 1: Week 1 and 2 (go over adding and subtracting up to 10)

Ready to play a game?!?! (give out candy/toy to every student that tries)

(switch to document camera. Use red/yellow circles on "5x2/10 grid paper". Go over various math problems using #'s up to 10. Have students pair up and give them their own circle and grid paper. After lesson, pass out worksheet.)

Part 2: Week 3 and 4 (go over adding numbers up to 20).

Game part 2!!!
