Math

A couple of the math activities that we do regularly.

Until now Lamb has been focussing on building a staircase with the cuisenaire rods and learning their progression  by naming the colours.

Today I introduces the concept of naming them by numbers rather than colours so that we can start to do meaningful equivalency activities with the rods. Here Lamb is working out what the number for each coloured rod should be by counting the 'ones'.

We found this book on halves at the library so I set up an activity for Lamb with buttons so that he can work out what the half of a certain number is. Here is placing one button on each semicircle until all ten are placed at the end of which he says "Half of ten is one, two, three, four, five".

I did a few other cardboard circles to introduce the idea of thirds and quarters too and while doing them Lamb ran to get the pieces of his Melissa and Doug pattern blocks to make up the hexagons in the same way.

Whole, halves and thirds.
