Dear Family, your Operation Maths guide to 2-D Shapes

Category : Uncategorized

Dear Family, listed below are some practical suggestions as to how you might support your children’s understanding of the maths topic of 2-D shapes. Also below, are a series of links to digital resources that will help both the children, and you, learn more about 2-D shapes. The digital resources are organised according to approximate class level.

Junior Infants to Second Class
You can also find class specific tips at the back of your child’s Operation Maths At Home book, for infants to second class, and in the Operation Maths Dear Family letters for third to sixth class.

Practical Suggestions for all Children

  • Why do children need to learn about shapes? Learning to recognise different shapes not only helps children learn about this maths topic, but, in the early years, it also develops their ability to recognise numbers and letters by their shape. This skill will also transfer to other signs and symbols, be they maths symbols such as +, =, <, > etc., or signs and symbols in the real world e.g. road signs, safety signs etc.
  • Naming shapes: 2-D shapes is short for two dimensional shapes, i.e. shapes with length and width, but not depth/height. Also called flat shapes, these include circles, squares, rectangles, triangles etc. 2-D shapes can be a bit confusing for both adults and children; for example, a real ball is not a 2-D shape, it is a 3-D object called a sphere, but if a ball is drawn, or shown in a picture, then the flat representation of the ball in the image is now a circle! And a box is not a 2-D shape, it is a 3-D object called a cuboid, but the flat surface of a box is usually the 2-D shape of a rectangle or sometimes a square. So, if looking for 2-D shapes at home, ask the children to examine the flat surface of objects and/or to look at the flat shapes in a picture book or magazine.
  • Shape hunts: Play games like “I spy, with my little eye, something the shape of a rectangle” etc. Again, be careful that you affirm with your child that it is the surface or face of, for example, the door, that is a rectangle, not the entire door (which is in fact another cuboid i.e. a 3-D object). Look out for 2-D shapes on posters, road signs, billboards, wallpaper and in picture books.
  • Properties of Shapes: 2-D shapes also have properties or characteristics that make them different from other 2-D shapes. A shape with three straight sides and three angles (also referred to as corners or vertices) is always a triangle…but as the children get older they will also realise that some triangles have three equal sides (equilateral), some triangles have only two equal sides (isosceles) and some have no equal sides (scalene). Through an understanding of what makes a shape that shape, the children can start to group shapes with similar properties or characteristics together. So, if exploring 2-D shapes, draw the children’s attention to properties such as the number and type of sides (equal, not equal, straight or curved), the number and type of angles/vertices (equal, not equal, right angles or not).
  • Play, play, play! Encourage your child to play and explore with 2-D shapes as much as possible:
    • Make 2-D shapes with sticks, string, playdoh, pastry, creating imprints in sand, mud, pastry, etc. Use construction toys such as Lego, K’nex, Geomag and Plus-Plus to create 2-D shapes and then build them further into 3-D structures.
    • Draw 2-D shapes and cut them out, create pictures, patterns, designs etc. Perhaps you have a spirograph toy somewhere in the house? Dig it out and give it a spin (excuse the pun!).
    • Solve shape puzzles. One of these are tangram puzzles. This ancient Chinese 7-piece puzzle, provides an excellent way to develop a child’s ability to manipulate and visualise shapes. You can often buy reasonably priced plastic or wooden tangram puzzles in local book and toy shops. You can also print out a set of trangram pieces and use them to solve the numerous puzzles available on line. Or you can play an interactive tangram puzzle game.
    • Other very worthwhile shape puzzles include tetrominoes (like the Tetris game of old) and pentominoes. You can also download games, based on many of these shape puzzles to your device; just search your app store for tangrams, tetrominoes/tetris and/or pentominoes.
