Today we will have a re cap on subtraction. Show the signs below and ask your child to tell you what they mean.
Subtract means to "take away" so the number will be smaller. We have looked at different strategies in class for subtracting;
- Using fingers, for example, 10-5= show 10 fingers, put 5 down, count how many are left.
- Using drawings and crossing out. (See example below)
- Using objects, 9-4= counting out 9 lego blocks, putting 4 back, counting how many are left.
