We tried making 2D and 3D shapes out of marshmallows and cocktail sausage sticks - very sticky.
We made a square, cube, rectangle, cuboid, triangle, triangular prism, a pentagon and a hexagon. It wasn't possible to make a cylinder or sphere. We could see that the shapes made using triangles were the strongest - that's why you see so many triangle shapes in bridges and cranes. Next we made our own 3D shapes: with 3D jigsaw pieces,
beads and connectors, flat triangles and squares,
flat window shapes
and with magnetic pieces.
Each group had a different activity, and we will swop around for the rest of the week. We managed to make squares, triangles, rectangles, cubes, cuboids, a pentagonal prism, triangular prisms, triangular pyramids and square pyramids. We really are good at making and naming shapes.
We are getting taller each day, our hands and feet are growing, and so is the rest of us. Teacher measured each of us, and we put stickers on the door frame to see who is taller or smaller than who. We like looking at this, and we know that each of us is the exact right size for our families, even if we are very tall or very small in this class.
We drew round our feet and hands, then coloured them in. Today we used coloured matchsticks to measure how big our feet and hands are. It was very interesting.
Next we used the matchsticks to measure how long our arms are (from middle finger tip to elbow), and to measure our hand spans (from thumb to baby finger).
We also took lots of pictures so you can see how we did our measuring.
Here is what we decided. We had great fun talking about how many liked each and how many more or less were in each group.
