Sorry to be posting so late. Tonight’s homework was a page asking students to find one less than a number. This was introduced today and seemed tricky for some of my students. I showed them how to use a number grid to find one less or two less or three less (etc.) of a number. I really want them to understand that less than means smaller than, which means to take away or subtract.

2 less than 8 means:

8-2=6

5 more than 13 means:
13+5= 18

Let’s keep working on this 🙂 Thanks for your help.
