Math: Subtraction with Fingers
Fingers are very useful at a young age to see an abstract concept such as subtraction become a concrete visual for 'taking away'. The kids will be practicing a variety of subtraction statements such as this:
There are 4 apples in the apple tree (put up 4 fingers) 2 apples fall off the tree. (take down two fingers) How many are left? 4 apples take away 2 apples is 2!
They will also learn another finger technique called 'Touch and Count Back’. Let’s say there were 7 birds in the tree and 3 birds flew away. I’m going to touch my head to keep 7 in my brain and count back 3 using three fingers. 7 (touch head)…6, 5, 4 (counting using your three fingers to hold a place for each bird that flew away).
7 take away 3 is 4!
I have 5 shirts and 2 get dirty. How many are clean? I will put 5 in my brain and then count back 2! 5….4, 3 (holding up one finger for each dirty shirt). 3 shirts are clean.” This concept can be VERY difficult for some and will take lots of modeling.
