Estimation Challenge

At the end of January, I attended a day's maths training. It was good, I got lots of good ideas. The one that stood out was this one:

I sat next to a lady, whose name I didn't find out, let alone what school she was from (if I find out, an update will be added). She gave me the following idea.

Ask the children to fill pots and containers at home with 'stuff'. For example, paper clips, pebbles, marbles and so on. Then, each week, put one of these on display and invite the rest of the class to estimate the number of items in the container. Ensure the child setting the challenge know the answer.
