Count the Crayons

These solutions refer to a previous version of this activity which used different pictures.

We had a small number of solutions sent in for this activity. This is a different kind of activity and maybe you found it hard to write about it.

I think that the first one has around 30, I think this because if you look at the bottom set of the first picture then there are around 15 pencils. The second picture looks like it's in the 60 or 70's. It is not as easy to estimate as the first picture because it's all mixed up.

The answer is 30 but my estimate was 28. So close. My method was estimate the top then double the answer.

Thank you for these two ideas for performing an estimate.
