Using Magnetix to Explain Quadrilaterals


Magnetix are construction toys, but they are also very useful for teaching about space and shape.  I get children to make different shapes with them, including 3D shapes.  But in this article I am focussing on quadrilaterals, because they can be the most confusing ones to learn about.

Here is how not to do it……..

Naming quadrilaterals

For each shape children need to know:

  1. number of sides

  2. length of sides – whether equal or not

  3. sides parallel or not

  4. interior angles

Square

  1. 4 sides

  2. all sides equal length

  3. opposite sides parallel

  4. all interior angles 90 degrees

Rectangle

  1. 4 sides

  2. 2 long sides, 2 short

  3. opposite sides equal length

  4. opposite sides parallel

  5. all angles 90 degrees

rectangle

Rhombus

To make a rhombus, just make a square and tilt the sides.

  1. 4 sides

  2. all sides equal length

  3. opposite sides parallel

  4. none of the angles are 90 degrees, 2 acute angles, 2 obtuse

rhombus

square to rhombus

Parallelogram

To Make a parallelogram, make a rectangle and tilt the sides.

  1. 4 sides

  2. 2 long sides, 2 short

  3. opposite sides parallel

  4. 2 acute angles, 2 obtuse, no right angles

parallelogram

rectangle to parallelogram

Trapezium

  1. 4 sides

  2. One pair of parallel sides

Kite

  1. 4 sides

  2. 2 long sides, 2 short

  3. no parallel sides

  4. the 2 sides next to each other are equal length

But if you haven’t got the time or struggle to explain things simply to your child, let us do the work for you.  Book your child for a free assessment and let us take care of things.
