First day back from Spring Break! We created a list of twelve of our favourite ice cream flavours, and then students were asked to find the total possible number of combinations of 2 scoop cones. Two scoops of the same flavour were allowed, and each combination counted once (ex/ 1 chocolate topped by 1 vanilla was considered the same as 1 vanilla topped by 1 chocolate).
There were lots of different answers at first (ranging from 68 to 144) with lots of great reasoning given. I encouraged groups to use manipulatives. Some groups were asked to start exploring 3 cone combos too!
We had some extra time, so we looked at different ways of solving 3.75 ÷ 0.75 that weren’t the algorithm. A few different approaches were shared – yay!
