I printed the first two pages, placed them in page protectors x 30 for a class set of instructions.
I sat students in groups of 4 (for the purpose of sharing a bucket of integer tiles...mostly working individually).
As a class, we walked through modeling with integer tiles for the first two problems. Then I allowed students to work at their own pace through the document.
(There are challenge questions at the end for quick finishers.)
The next day we drew circles (instead of using the concrete models) as we simplified expressions with integer addition - this part not included!
Two days later we used the same lesson format for the subtraction pages.
*2 chapters later, we still talk about adding red tiles and red tiles ...they can't magically turn yellow! (Once students find that a negative times a negative equals a positive they tend to think that a negative plus a negative equals a positive.)
