Please watch the video below to learn about how we can use our understanding of dividing by 2 to help us recognise and explain odd and even numbers. If your child has found learning on odd and even numbers tricky in the past, this may help develop their understanding better. If they already have a good grasp of odd and even numbers, this will help them understand the maths behind it even more deeply. The worksheet and practical activities are then provided below.
The practical activity on the pdf below can be carried out without printing. You could write the numbers 1 to 10 (or 1 to 20 to extend the task) on pieces of paper then put counters on or sort them into numbers which do divide exactly between the two and numbers which have a bear left over.
Once you've explored odd and even numbers by dividing by 2, either on the worksheet or the first practical activity, you might like to use your knowledge to spot and explain the mistake on the table below.
Problem solving is provided in the Word document below.
