Over the last few weeks, Primary 3 have been developing their understanding of 2D and 3D shapes. We have completed lots of fun learning activities and applied our knowledge through different stations.
“The ‘D’ in 2D and 3D shapes stands for dimensions.” (Connal)
“2D shapes are flat but 3D shapes aren’t because we can pick them up.” (Olivia)
We started by exploring different 2D shapes, looking at their properties and revising the names of different shapes.
“Normally the number of edges and the number of corners on a 2D shape is the same.” (Eva D)
We then hunted around the school to see what 2D shapes we could find.
We made and repeated different patterns using peg boards and playing games.
“Patterns repeat themselves over and over again.” (Finlay)
We also looked at tiling patterns.
“Tiling is when shapes can join together with no gaps or overlaps.” (Fraser)
“Some shapes that tile are trapeziums, triangles, hexagons, rectangles, squares and parallelogram.” (Kaiden, Holly and Olivia)
We also investigated different angles that can be found in 2D shapes and used Beebots and our coding skills to give directions turning through a right angle.
“2D shapes can have right angles like a right angled triangle.” (Ryan)
“90 degrees is a right angles. If it is less than 90 it is an acute angle and if it more than 90 is called an obtuse angle.” (Fraser)
Following on from our 2D shape and angle investigation, we explored 3D shapes looking at their properties and what 2D shapes are used to make 3D shapes.
“We looked at the number of faces, corners and edges of 3D shapes.” (Natalia)
“3D shapes have a depth but 2D shapes do not.” (Murray)
We used construction materials to build different 3D shapes using 2D shapes.
“2D shapes can be used to make 3D shapes. For example, a cuboid is made of 2 squares and 4 rectangles.” (Dilraj and Finlay)
