reSolve: Reasoning With 3D Objects

This sequence of lessons explores symmetry and three dimensional objects. Students interpret and represent three-dimensional objects in two dimensions and apply their knowledge of transformations to show congruency or difference between objects. The lessons are outlined in detail including curriculum links, vocabulary, ...

Skeleton Shapes

This resource is a web page containing a practical task to model 3-D objects. The task suggests the use of straws and modelling clay or similar material to create a model of firstly a cube and next other 3-D objects. A printable resource is also available to support the task. This resource is an activity from the NRICH website.

How does your garden grow?

This Stage 2 resource grew from a conversation between young students questioning why they could still buy grapes if they were out of season. This wondering led to a discussion around when we grow certain fruit and vegetables. The original stimulus was extended to cover planting for the seasons and factors that influence ...

Introduction to Shapes Year 2 - Calculate

The focus of this activity is to discover the language that students are using to describe the features of shapes. Although students may know the names of many shapes, and may know the difference between a square and a circle, the description of why these shapes are different may not be mathematically accurate. Listen to ...

Pattern Blocks - Calculate

This activity uses pattern blocks to explore patterns and the relationship between numbers. Students use the blocks to create and describe other shapes and since the blocks are relational they can be used for other investigations. For example, turn the blocks into units – if the triangle is one what is the value of the hexagon?

Mixed Up Maths, Ep 7: Daredevil geometry

What does a daredevil jumps rider need to know about geometry? Find out as we discover angles for take off and for landing. But before we do that sit down for some angles basics! A good place to start is angles of turn through a circle from a 1/4, 1/2, 3/4, all the way to one full turn. See how many each represents as an angle.
