Elephant wants to build something tall. Something as tall as Elephant. But will it stay up? Crash boom! Boom! No, not this time... Hmmm... Build it again? 1 block. 2 blocks? 4 blocks? It’s still not as tall as Elephant. More blocks! Now will it stay up? Now will it be as tall as Elephant? Build, balance and count; question, estimate, measure; predict, crash, and build again with Elephant and a bucket full of blocks.
