Introduction
(10 minutes)- Tell students that today you are going to teach them how to subtract two-digit numbers.
- Think of a short word problem that uses subtraction with two-digit numbers. For example: 36 children are out on the playground. A teacher comes out and calls 17 of them back in. How many children are left on the playground?
- Solve this problem on the board by lining up the place values and using regrouping to break up the digit in the tens place to create enough ones to subtract.
