Shape and weight

We investigated 2D and 3 D shapes using different materials. 

We stamped 3D shapes into playdough to see what shape the faces were. We created pictures from 2D shapes. We thought what shape real life objects are, and sorted pictures into those that were cubes, cuboids, cylinders, cones, pyramids and spheres. How many faces do these shapes have?
Can you look around your home and decide what shape different objects are? (Such as a cereal box, a ball or a yoghurt pot)



We used building blocks to build with, and thought about what shapes they were. Shapes were created with marshmallows and cocktail sticks such as triangles and cuboids. 
How many sides does a triangle, square, rectangle, circle, pentagon, hexagon and octagon have?


Wow! You made a church shape at home and brought it in to show the class. Fantastic building work. What shapes can you see on the side of the church?


We created a map using the shapes of the United Kingdom? What are the best shapes to use for roads?




We also looked at weight. We held an object in each hand and thought about which was heavier and which was lighter by noticing which arm went down (heavier) and which went up (lighter). We had to investigate with wrapped up boxes to find which was heaviest. Sometimes the biggest box was lighter and the smallest heavier, this surprised us but made us realise that you can't measure weight by looking at objects, you have to hold them and compare their weights.


Balances and scales were used to accurately weigh objects. We had to weigh 3 different objects and put them in order from the lightest to the heaviest.



We used grass and kilograms for the first time to weigh a carrot, pear and an apple. We had to use our understanding of 10s and 100s to count with accuracy.
