# Maths time in Room 15

### Room 15 has been doing lots of maths learning.

We have been making, recognising, ordering numbers to 20, counting forwards and backwards to 20, saying the number before and after to 20, skip counting in 2,5,10, recognising number bonds for 10 and solving addition and subtraction problems using materials.

Our class always enjoys using the materials to find interesting ways to learn new concepts. Lots of fun has been had with our new dexterity hands-on activities like ordering numbers and sounds using pegs on a clothes hanger, threading beads on pipe cleaners to make repeating patterns for our custom made jewellery and catching foam numbers/letters with our mini fishing nets to practice sequencing numbers to 10 or 20.

Our strand focus this term has been measurement. We have been learning to Order and compare objects by length, area, volume, capacity and weight using non-standard units. During these sessions we have had lots of fun comparing the lengths of different objects like snakes we made with play-dough, identifying which of the “Three Bears” bowls had the most popcorn in it (capacity and volume) and seeing which farm animals covered the least/greatest area with its footprint.

I asked the students how we would be able to compare which of the Three Bears had the most popcorn in their bowl (of course the bowls varied in height, width and shape) - one of them confidently said “we need to pour each of the different bowls into a bowl that is the same size to compare them, how about we use a plastic cup.” They have now discovered that in order to precisely compare objects they need to use a standard unit of measure like cubes, containers, footprints, shapes etc.

The comment that it was not showing “whanau” if Mrs O’Sullivan or Tracey got a handful of popcorn and they got a handful as our hands were so so big and theirs were very very small (priceless).
