SMT currently making sure all lessons have challenge for MA children. So having a quick 10 minute drop-in in my maths this week. Have horrid cold/cough thing and not too inspired. We are doing shape and this is the first week. Most of the children know 2d shapes, so introducing 3d (which the MA mostly know - not all secure on cone). For MA I was going to bury shapes in the sand so that 1 face is visible and then get them to decide on the 2d or 3d shapes that it could be (without touching) so eg a circle visible at the surface could actually be 3 different shapes. I would ask them to work as a team or in pairs so they could discuss between themselves.
