1) 1 more & 1 less
2) 10 more & 10 less
3) 100 more & 100 less
Great review for students and these concepts.
Go forward in the PowerPoint to do MORE
Go backward in the PowerPoint to do Less
Example: Display number and ask students what 10 more is...and then show them the answer directly as they are saying it.
Great for Visual Learners!
