I recently bought buttons and containers from Ebay and decided to use these to teach division today.
The containers have 10 sections each. This activity was very practical as the children imagined they were sharing the buttons between people and easily understood what they needed to do to solve the problem.
I gave the children a division problem. e.g. 28/4 =
The children then got 28 buttons.
They shared them between 4 sections.
They then counted how many were in each section. (Finding the answer)
The children really enjoyed using concrete materials and were able to answer all questions given (even those with remainders).
