Perimeter and Area 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, trapezium and parallelogram. Ages 9  13 3 pages of teachers notes and 5 pupil copymasters. (pdf) 
GBP £0.80


Populations 

Investigate the populations of towns or countries and learn how to work out how many more people live in one town than another and how many times bigger one town is compared with another. Consolidates skills in reading, rounding, subtracting and dividing large numbers and choosing an appropriate scale for a bar chart.

Properties of Quadrilaterals 

Find out why a square is a special kind of rectangle but a rectangle is not a special kind of square! Explore the differences rhombuses and parallelograms, kites and trapeziums. Investigate questions like 'Is there a quadrilateral with three acute angles?' A practical approach using construction material such as geostrips. Ages 9  13 3 pages of teachers notes and 7 pupil copymasters. (pdf)

Pythagoras Puzzle 

Have fun making this simple puzzle which very beautifully illustrates Pythagoras' Theorem that the sum of the squares on two sides of a rightangled triangle = the square on the third side. Make and solve the puzzle and then through measuring areas discover Pythagoras' Theorem. Ages 8  15 1 page of teachers notes and 3 pupil copymasters. (pdf)

The Algebra of Throwing 

Children often ask what algebra is FOR. This investigation allows capable pupils at the top end of primary school to use simple algebraic skills to investigate an area of Maths that is normally reserved for upper secondary pupils.
Children love throwing things in the air. By the end of this investigation they will have equations, tables and graphs that will allow them to work out how high they can throw something, and what speed they can throw it at. Beware. It is good fun! Ages 10  13 2 pages of teacher's notes and 18 pupil sheets. (pdf)
