While sorting stuff in the bookcases to be replaced I found a jar full of coins. Kids were happy, especially Anna, whose interest in money is pretty strong at the moment, and since I also found her Dikkie Dik piggy bank standing empty. So I told them they could have the money if Anna counts it and Alexander helps her to divide it equally between the kids.
So, what has happened in the next hour?
- Anna was learning how to count money (and how not to walk around with her piggy bank especially when she is very excited with the money there).
- Alexander was practicing checking if a number could be divided by 3, writing decimals, helping Anna without doing the task instead of her and finding the easiest possible way to do calculations when I asked him to add up the numbers.
- Emily was very sad that she didn’t have a piggy bank, so she wanted to go and immediately buy a pink piggy to store her part of the treasure. This is when Robert came to the rescue with the suggestion to build a pink piggy bank from Lego.
[In a couple of days] All three kids have 3,15 euro of the treasure and 3,09 shared, which is not enough to buy three ice creams of 1,50. Alexander found a way to take an equal contribution from everyone, but then had 1 cent left. Of course, I told him that it was not possible, given that 3,09 could be equally divided by 3.
So now we are at: different strategies to deal with the task, importance of estimations and checking if everything adds up, division by 3, addition and subtraction of decimals.
