Activity A - NRICH Making longer, making shorter

This activity includes doubling, halves and quarters in a very practical way using rods made from interlocking cubes. It gives children a practical context in which to explore simple multiplying and dividing, even if these particular terms are not used explicitly. It can provide a very useful context for introducing and using the vocabulary of halves and quarters.

Having multilink cubes for each child is essential.

Activity B – NRICH Happy Halving

This problem consolidates children's understanding of halving and will help them to develop their skills of visualisation.

It is important pupils are clear that, in this problem, the halves must be exactly the same size as each other. A precursor to this activity might be to show the group a square and ask them to split it in half in their "mind's eye". By discussing where they have imagined the "cutting line", the children will discover that there is more than one way to do this. From this point, you can talk about whether or not the two halves are the same size each time.

It may be useful for the pupils to have a sheet of the shapes. Alternatively, they could use a pegboard or geoboard to try out their ideas.
