###### Drawing Straight Lines

Children can have real trouble drawing lines accurately.  This is a skill that needs carefully taught.  This activity teaches how to draw straight lines using a ruler to join dots on spotty paper....

###### What is area?

This activity introduces the concept of area as the space covered by a flat shape and explores how areas can be compared by counting squares.  Once we have learned the concepts, we are given an open...

###### Lines, Angles and Shapes

This single resource allows for the consolidation and development of a wide range of mathematical skills and concepts, covering line, angle, shape, symmetry, area and proportionality.  It can be...

###### The Great 2D Shape Investigation

An umbrella investigation stimulating a wide variety of explorations into 2-D shapes. Depending on the lines of enquiry that develop, you can then use material from related investigations such...

###### Angles in Polygons

Investigate the total interior and exterior angles of polygons (triangle, quadrilateral, pentagon, hexagon etc.) Explore patterns in the numbers and establish rules and experiment with formulas.

###### Constructing Shapes

Constructing shapes with compasses is always great fun because you get pretty patterns. But this investigation goes well beyond regular activities with pupils being given an open-ended challenge to...

###### Angles in Triangles and Quadrilaterals

Investigate the angles in different triangles and quadrilaterals and discover the facts about their totals.

###### How Many Different Kinds of Triangle Are There?

How many different kinds of triangle are there? Can you have a triangle with two obtuse angles? These and other questions are all explored in this practical investigation using geostrips (or...

###### How Big are Cuboids?

This is an open-ended extended exploration designed to be used over multiple weeks.  Each section builds on the learning from the previous one but is does not need all to be completed at once. It...

###### Perimeter and Areas of Triangles and Quadrilaterals

You may be able to calculate the perimeters and areas of a rectangle and a triangle, but can you explain why the formulas work?  Build on this to explore other quadrilaterals: rhombus, kite,...

###### The Egyptian Triangle

Discover the special triangle that the Egyptians used in their buildings, while learning about how simple decimals work, the importance of accurate measuring and how to work systematically to solve...
