We would count our sticks together to make sure everyone was starting with the correct number. Then we'd share the sticks equally between three pigs.
We'd check to make sure each pig had the same number, and then one of my kidlets would give the answer in a sentence. E.g. Twelve sticks shared into three equal groups leaves four sticks in each group.
I even introduced the idea that not all shares can be equal. We tried to divide seven sticks between the three pigs and discovered that we would have one left over.
This activity is so easy to adapt depending on the resources you have in your classroom. Last week we used little rubber ducks from the dollar store and divided them into two groups using blue paper for a pond, and next week we will use teddy counters and 'picnic rugs'.
If you'd like to do this with your class, I've uploaded the file to my TpT store as a freebie. :)
