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.

Guess My Shape or Object - Calculate

The focus of this activity is to encourage and support students to describe two dimensional shapes and three dimensional objects according to their features or properties.

Text

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?

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 ...
