My own first grader was struggling with mentally adding 100 to numbers, so I created these pages to help her organize the numbers by their value {hundreds, tens, ones} so she could visually see how adding or subtracting 100 changes a number.

If your learner is still struggling, a teacher tip is to add base ten blocks to your lesson so learners can manipulate adding and subtracting 100 from a number. This makes this activity multi-sensory, engaging learners’ ears, eyes. Having the blocks also makes an abstract math concept more concrete.

 

Thinking and Talking about Math

After solving the math problems, learners are encouraged to think and share verbally how adding or subtracting 100 changes the number. Which digit does it change? Why is that?

I love this step, and do not recommend skipping it!

This is when your learner gets to turn around and “be the teacher” to explain WHY it works the way it does.

This is KEY because learners might understand the “what” or even the “how” with math but not understand the “why.” And the “why” is what helps them move from a basic understanding to a deeper understanding that they can apply. Application is KEY with math concepts!
