These lesson plans guide the teacher on how to introduce trigonometry to students through an investigation of similar triangles.

• TLF-IDA003567

This comprehensive resource describes the progression of measurement ideas. The resource demonstrates examples of relevant teaching strategies, investigations, activity plans and connected concepts in measurement including teaching and cultural implications.

• TLF-IDA003165

This planning resource for Year 6 is for the topic of Angles and parallel lines. Students explore angles on a straight line and angles within shapes. They identify the relationships between angles and use these to determine unknown angles and describe their reasoning. Students should be familiar with 90° and 180° angles, ...

This is a website designed for both teachers and students that introduces congruence of shapes in the plane through transformations. In particular, transformations, translations, reflections in an axis and rotations of multiples of 90 degrees are used to define congruence and to identify congruent shapes. The four congruence ...

This lesson explores the geometry of cutting polygons in different ways and using algebra to express subsequent findings. Students use one straight cut to divide a convex polygon into two new polygons. They make generalisations about the total number of sides of the two new polygons, and about the number of different combinations ...
