2D shapes

This week in maths we have been learning our 2 dimensional shapes. We have learnt they are flat shapes. We know their names

  • circle
  • triangle
  • square
  • rectangle
  • pentagon
  • hexagon
  • octagon

We also know that these shapes have magic numbers. A circle has 1 because it has 1 side all the way around it. A triangle has 3 sides and 3 corners, so it’s magic number is 3. Squares and rectangles have 4 corners and sides, there magic number to remember is 4. We know a rectangle has 2 long and 2 short sides, that’s how we don’t get it mixed up with a square. Pentagons look like a house with a roof and have 5 sides and corners. Hexagons have an x in the word just like the letter 6- and a hexagon has six sides and corners. An octagons has eight sides and corners and we remember it like an Octopus with 8 arms.

We have been on shape hunts around school looking for 2d shapes. We have made shape monsters which will be on display on our working wall very soon.
