You will need a cut-out paper circle (about 12cm diameter).
Use a circle that does not show the centre. Fold your circle along a diameter. Mark the ends A and B. Now unfold your circle and then fold again along a different diameter and mark the […]
We take it that you know that in a parallelogram both pairs of opposite sides are parallel.
In this investigation you will discover some other properties of parallelograms.
Step 1: Use two rulers with different widths to draw a parallelogram on tracing paper or baking paper.
Make sure that it is not a […]

What do you notice about this shape?
Describe the shapes of the tangram pieces.
What is the same and what is different about the shapes of the tangram pieces?
Make a pattern of your own using all 7 pieces.
This lesson is first about using properties of quadrilaterals to identify particular shapes and second about identifying the smallest number of properties needed to define a shape. This activity should be given to the class as a formative assessment activity: it is designed to provide the teacher with information about the learners’ current levels […]
