Day 11–Halves

day 11 together

I overheard several student comments today regarding “halves”  so we pulled out the pattern blocks and built some.  Everyone was able to do so, most of them building 2 identical halves.   Tonight’s homework was to reconsider these photos from students who used different blocks for each half.  1/3 of the class stated both pictures correctly represent halves.  1/3  disagreed, claiming the picture with the red trapezoids separated is incorrect.  1/3 were undecided.  Looks like a long road ahead….
