We noticed lots of patterning happening too!
At circle I placed the presents in a pile in the middle of the carpet and invited the children to estimate how many they thought were in the collection. They had very reasonable guesses, with many children's estimates falling in between 50 and 80.
I asked the children how we could quickly and efficiently count the presents. They suggested placing them in groups. At first groups of 3 was suggested but we decided this wasn't a friendly enough number (because then we'd have to count by threes, which can be challenging) so we decided to group the presents in fives.
We wanted to double check our work so the idea of placing the presents in order using a hundreds grid was suggested. Our final count was 50!
