RP are Super Mathematicians! person Mrs Penavega date_range 18/01/2015 comment 1 Comment on RP are Super Mathematicians! This week in RP we have been learning about capacity. We used the sand tray to fill and empty cups. We could also half fill a cup and put a little bit of sand in the cup so that it was nearly empty! We are also learning about positional language. Can you say where Aaron is standing? Where is he going?
