Comparing the volume of a cube and a cuboid tutorial. Let our digital teacher show you how to compare the volume of a cube and a cuboid, then see if you can answer the on-screen questions she sets. Cut out these shape names. Can you organise them into two piles, one for 2D and one for 3D? Look around the room. Can you find an object to match each shape card? Stick the card to the object with Blu Tack!
Calculating the perimeter and area of irregular shapes. Once you know how to find the area of a rectangle, you can use this knowledge to find the area of irregular, compound shapes as long as they are made up of rectangles or squares. Can you calculate the area and perimeter of the shapes below? Formulas for calculating area and volume of shapes.
The quickest way to find the area of a 2D shape is to use a formula. Can you use the right formula to find the areas of these shapes? With 3D shapes we can also find the volume, which means the quantity of space taken up by the shape.
Can you use the right formula to find the volumes of these cuboids? Join TheSchoolRun today Primary Geometry: shape and space The tricky part of geometry, for many children, is the large amount of geometrical vocabulary that they will need to learn, remember and use correctly.
