Draw polygons on isometric paper
I can draw polygons on isometric paper.
Lesson details
Key learning points
- Different patterns on the paper allow you to draw polygons with different properties.
- A ruler helps to draw shapes accurately.
- Mark the vertices of the shape and join them with a ruler to create polygons.
Keywords
Isometric - Isometric means distances between points stay the same. In this lesson we use isometric paper which has equally spaced dots or points.
Perpendicular - Two lines which meet at a right angle are perpendicular.
Parallel - Parallel lines are straight lines that are always the same distance apart. They never get closer together or further apart.
Common misconception
Pupils may not identify when a polygon has more than one pair of parallel or perpendicular sides especially when the polygon is not a rectangle.
Make use of right angle checkers to identify that some shapes have more than one right angle and take time to link this to perpendicular sides.
