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.
Ages 9  13 4 pages of teachers notes and 10 pupil copymasters. (pdf) 
GBP £1.40


Angles in Triangles and Quadrilaterals 

Investigate the angles in different triangles and quadrilaterals and discover the facts about their totals.
Ages 8  12 3 pages of teacher's notes and 4 pupil copymasters. (pdf) 
GBP £1.90


Chopping up a Metre Stick 

Well, not ACTUALLY cutting it up  but imagine...
Suppose you wanted to make 4 pieces or 5 pieces. Where would you chop? How about 3 pieces? Get totally immersed in how division, fractions and decimals work... Ages 8  12 3 pages of teachers' notes and 16 pupil copymasters. (pdf)

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 openended challenge to create as many different types of shape as possible using a pair of compasses and a straight edge. You first learn how to construct an equilateral triangle, how to bisect a line to make a right angle and how to bisect an angle. Armed with these three simple techniques see what other shapes you can create. Square, rectangle, kite, rhombus, trapezium, parallelogram, hexagon and octagon are all possible! Ages 9  13 1 page of teachers notes and 5 pupil copymasters. (pdf) 
GBP £1.00


Election Results 

Compare the results of a recent election with a previous one and present findings using a hand drawn pie chart. Covers the skills of expressing quantities as percentages and calculating pie chart angles as well as basic skills in interpreting tables.
Ages 10  14 4 pages of teachers' notes and 8 pupil copymasters. (pdf) 
GBP £1.20


Equations through Pictures 

Straight line graphs are often not taught until somewhere in the middle secondary years. But they can actually be an excellent way of helping younger children to explore how equations work if you introduce them in the right way. This investigation shows you how.
Ages 10  13 4 pages of teacher's notes and 3 pupil sheets. (pdf) 
GBP £1.80


Flights 

An investigation into flight times for an aeroplane between different places. Covers map scales, averages, conversion tables and speeds.
Ages 8  12 2 pages of teacher's notes and 9 pupil copymasters. (pdf) 
GBP £1.20


Formulas for Sequences 

Investigate he connection between number sequences and the rules that generate them. Begin by exploring two simple matchstick patterns and develop into investigating line graphs for formulas.
Ages 11  14 5 pages of teachers notes and 5 pupil copymasters. (pdf) 
GBP £1.20


Handshakes, Cards, Roses and Triangles 

An investigation into four related problems which all generate number patterns linked to the triangular numbers: 1, 3, 6, 10 etc. Consolidates pupils' use of problemsolving strategies such as drawing diagrams and using tables and shows how to investigate a problem thoroughly by building a pattern from simpler cases to more challenging ones.
Ages 10  13 7 pages of teacher's notes and 10 pupil copymasters. (pdf)

How big is the room? 

How do you introduce decimals to young children? This practical investigation works a treat, and also gives you the opportunity to discuss accuracy in measuring, averages and perimeter!
