This week we tackled subtraction with 3 digit numbers in math. More specifically, we worked on subtraction with regrouping. For those of you as old as I am, you may know it as subtraction with borrowing. It's really the same thing. But instead of calling it "borrowing" from the tens column, we "regroup" a ten, into the ones column as ten ones.
Subtraction with regrouping can be tricky for many children. Click here to see a video that your third grader can watch to help review the concept.
Ask your child how they know whether to regroup or not!
Please let me know if you have any questions, comments of concerns.
