You try!
764 - 592 You do the work on your whiteboard. Then, we will look over it together on my big whiteboard.
Remember to draw the first number 1st!

Can I take 3 away from 2? Why not?
What did we do with our place value blocks when this happened ?

unbundle one of the 6 hundreds!
What will that leave us with?

If you missed 0 – 1:
1. Do the workbook page.
2. Keep it at your desk when you are done.
3. Play a math game.
If you missed 2 – 3:
1. Find your mistakes and fix them.
2. If you know where you went wrong,
do the workbook page. If you can’t find me.
3. Keep it at your desk. If time, play a math game.
If you missed 4 – 6:
Bring your workbook page and pencil to the back table.
