Doubling and Halving.
Posted by Reception Staff on Wednesday May 15, 2019 Under UncategorizedAs part of our maths work this week we have been doubling numbers, (adding the same number to itself) and halving, (sharing a number in half, or even sharing things between many people or things). We completed a number of practical activities where we needed to sort out the pairs of doubles that were all mixed up in a tough tray. It was tricky but we did some excellent counting and matching.
Ladybirds are really good for doubling and we had a try at rolling a dice and doubling the spots and then making some of our own doubling ladybirds. The numbers need to be the same on both sides and some of the dice went up to 10. Some really tricky doubling.
Later on in the week we practised our halving and sharing, we needed to share biscuits or sweets cubes between the plates.
We read the story- Sharing a Shell, it has lots of sea creatures to share the shells between. The tricky ones had 4 characters from the story and 12 shells!
We also used play dough to make special items and then share those between different things.
If you have a look around online you will find lots of lovely games, and songs for doubling and halving. Here’s a link for our doubles song.

The children love the song and have been learning the doubles and their totals.
