NRICH Constructions
This list supports teaching of constructing shapes in secondary mathematics. It provides investigations, problems and games from NRICH as well as classroom activities on the STEM Learning website that compliment them.
Here is a favourite activity selected by the NRICH team.
- Constructing Triangles This problem involves constructing triangles. Students investigate which triples of numbers give lengths from which it is possible to construct a triangle.
These are just a few of the activities on constructing shapes that you can find on the NRICH curriculum pages.
The activities below, taken from the STEM Learning website, complement the NRICH activities above.
Coding a construction
This resource from the IET Faraday programme provides an ideal follow up activity to the NRICH problem 'Constructing Triangles'.
Students explore geometric constructions through the concept of machine programming. The resource explores how computer controlled machinery can achieve a range of constructions that use only compass, straightedge and a pencil.
Constructions
This activity from Defence Dynamics is an ideal for students to work on ahead of tackling the NRICH problem 'Constructing Triangles.
The activity presents a range of problems that involve using constructions in both warfare and peacetime defence.
Constructions covered include angle bisector, perpendicular bisector and triangles. Other topics required for this activity are scale drawings and loci.
Seaside
This video resource from Teachers TV is ideal to use prior to students tackling the NRICH 'Construction' problem.
The video was filmed at the seaside and covers construction of a triangle, similar triangles, scale drawing and loci. Questions are posed throughout the video with clearly signposted 'pause' points.
