This was created to model the answer to a problem in the Nelson Math textbook grade 4 "If Manitok has 15 small rocks, does he have enough to build 6 inukshuks like the block model?" The triangle pattern blocks are used to model small rocks. Try the program to see if he has enough.
It is modelled after Lisa's Youtube Videos that Diane shared. I attempted to add a visual/spatial images (as changing backgrounds) to add visual support for the learner.
