This morning you will be learning another strategy to do subtraction. We will be counting on to take away by finding the DIFFERENCE between the two numbers using the empty number line.
- We will be playing a game called CONVICT COUNT ON to explain how this strategy works in a fun way.
- You can have a go on your own later or at home to use the strategy online with this SUBTRACTION ON A NUMBER LINE activity. You can change how big the numbers are that you have to subtract and you can actually see the jumps.
You can also watch a couple of videos I made of this lesson, using an Empty Numberline to count on and count back to subtract. You can find it on Dolphinkids by following these instructions:
This makes subtraction SO EASY! 🙂
Let me know how you go.
