Algebra Tiles (with tile arrays) (Updated Link)
Just thought I’d share. Made some algebra tiles, but made adjustable arrays of them instead of individual tiles. Negative tiles can be made by moving the array adjustment point to the left (fill color will change to red and labels become negative).
Labels don’t show until they’re placed in the work area, but can also be hidden by just turning the folder off.
There is a folder with a list of counts for each array in the work array, as well as totals.
I haven’t made an activity yet, but would set the bounds in the CL:
