We placed six blocks around Sisi so the children could see about how much of her body those six blocks covered. The children were encouraged to guess how many blocks it would take to go all the way around her body. We decided that since we already used six blocks, our guesses would have to be a number higher than six.
For this problem, we know two things.
1.) We know that our guess must be a number. We want to know how many blocks it will take.
2.) We also know that it will take more than six blocks to go all the way around Sisi.
It's important for children to have many different experiences with each new concept we are introducing.
