At first we were confused so we started by placing beads in random places. Then we started moving the "candies" around so that they would follow the rules. Then we started seeing a pattern! We noticed that the same 2 colors were always in a row together so we just finished by following that. I ended up with 6 rows and 6 columns. Gabe had 4 rows and 9 columns. We used a
multiplication chart and saw that 6X6 = 36 and 9X4= 36 too! Here are their pictures.
