Math: Subtracting One
Today, the kids will focus on subtracting one with the use of a vertical number line.
Using the Ten in a Bed poem, the kids will raise 10 fingers and subtract one-by-one to notice that the number is getting less by one each time. My goal is to have the kids continue to notice the connection between less and subtraction. We will continue to use the vertical number line to demonstrate a subtraction problem like this:
5 birds were in a tree. 3 birds flew away. How many birds are left? We will find the number 5 and swoop down 3 spots to see there are 2 birds left.
