3 Blocks Towers


Jemima sent us her work on this problem. Well done, Jemima!

I used multilink cubes to make the towers. First of all, I looked for towers that were red at the top. Then I looked for towers that were yellow at the top. Then I looked for towers that were blue at the top. These are the ones I found.

David tried the problem with four blocks. Here are the towers he found:
