Expanding:2D Shape: Quadrilaterals 2 (Investigation)
opposite, adjacent, equal
quadrilateral, square, oblong
Hints and Tips
Your child has had the opportunity to investigate triangles.
Now he/she will be exploring quadrilaterals in more detail.
Remember that quadrilateral just means "four sides" so a quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.
Essential Prior Knowledge
Looking for patterns
This is a discussion and discovery activity about shapes and their properties.
Ask your child to either find pictures of, or draw quadrilaterals. He/she can either construct a chart or make a poster like ours.
Things to think about:
· Sides and their relationships e.g. length, parallel, perpendicular, opposite
· Angle sizes e.g. obtuse, acute
· Diagonals and how they meet
Encourage your child to draw each quadrilateral in a number of ways. Remember to draw or find both regular and irregular forms of each shape.
