Activities

Programme of Study statement Activity
A B C D E
Compare and classify geometric shapes, including quadrilaterals and triangles, based on their properties and sizes.  
Identify acute and obtuse angles and compare and order angles up to two right angles by size.      
Identify lines of symmetry in 2-D shapes presented in different orientations.    
Complete a simple symmetric figure with respect to a specific line of symmetry.        

Activity A - Stringy quads

Using a loop of string and three friends to investigate the symmetrical properties of quadrilaterals.

Activity B – National Flags

Many national flags were displayed during the 2012 Olympics Games in London. This activity investigates the properties of flags, e.g. lines of symmetry, and the properties of specific shapes within each flag.

Activity C – Shape and Space activities (The National Numeracy Strategy)

Short mathematical imaginings (on p3, 4 and 5) particularly No. 2, 3 and 11 encourage children to visualise and mentally manipulate 2D shapes.

Activity D - Symmetry Challenge

Systematically explore the range of symmetric designs that can be created by shading whole squares of a 3 x 3 grid.

Activity E – Triangles All Around

Using a circular pegboard with four, six or eight evenly spaced pegs, how many different triangles can you make? What are their angles?

Useful Resources

Sets of 2D and 3D shapes, Polydron, mirrors, pegboards, pinboards, rulers, dot isometric paper, 2-D shape dice, string.
