When exploring angles a Clinometer can be an excellent tool. They are relatively cheap and they give really useful reading from which children can draw triangles from the observer to a tree.
Concepts which can be investigated are:
1.The angle need to build a flying fox. Then constructing a drawing of the flying fox.
2. The angle a cannon would have to be pointed on castle ( introduce projectile as a straight line first)
2. The ideas of how this angle may help to determine height can be explored with older children.
This large Meccano was produced by me at Springfields school. It spawned a whole plethora of different teaching ideas. Here are a selection:
1. Shape Investigation
2. Angle Games
3.Builing and Costing a Rescue Shelter
4. Investigating Maths in Bridge Building Challenge
These are a great way of collecting data in a range of situations form activity to meditation. The cheaper watch ones tend to be unreliable and it is best to go for the full strap heart rate monitors.

There are a number of different robots available for maths at the Primary level. They teach sequential logic, counting and turning. The resources can be extended further by imaginative use of mats to include time based problems.
The two systems I like are Bebot and Bigtrack. The big track has a great expansion capacity and both retail at £29.99
As we develop further in primary into Y5 & y6; LEGOs WEDO can play a major part in the educational system. This is a full graphical programming language connected to LEGO machines which move and chomp. It enhance logical thinking and questions of percentage increase can be explored with output motors and cranes. The extent of maths which can be derived form these systems is very dependent on the teachers imagination. This is part of a major project under LEGO maths.
I believe even high functioning kids forget their number bonds. Using this simple way of getting students to comeback to counting and segmenting ensures that their mathematical brains develop correctly.
These have been with us for a great deal of time. However a revisit of this tried and tested resource is overdue.
The cube sets be used to explore the following problems really well:
Primary: number bonds, counting, area squares and rectangles, basic volume
Secondary: plan, side and elevation drawing, cube and square numbers, volume and surface areas of cuboids.
- Geo Strips can be a great way of making basic geometric shapes and discovering symmetry or the younger years
2. Knex for students of an older age
The knex system is ideally suited for geometry and angles. It allows for architectural construction and has an active user group involve in maths.
