The right angled triangles numbered 1, 2, 3 and 4 in the diagrams all have sides of length a, b and c. They are identical (congruent) copies of each other.
Cut 4 congruent right angled triangles from some scrap paper. Arrange them as shown in diagram […]
Look at this square divided into four pieces : two identical triangles and two identical trapezia.
The edge of length 3 from each triangle matches with the edge of length 3 from a trapezium so that the four pieces from the square now occupy a rectangular space.
The square had side length 8 […]
This jigsaw has 7 pieces and 3 solutions with variations of those solutions.
You can download the template here and cut it out or make it on card. Try the puzzle yourself.
Either make a square with 5 pieces or make a square with 6 pieces.

You will need a 0 to 9 spinner or ten cards. See instructions for […]
Another TARGET game for any number of players. You want to win? So THINK MATHEMATICALLY and ESTIMATE the likely answers. When you multiply H hundreds by T tens what do you want the product of the digits H×T to be? A bit less than 10 perhaps?
You will need a set of 10 cards […]
A game for any number of players. You want to win by getting the total close to 100, so THINK MATHEMATICALLY! Concentrate on the digits in the tens column. What do you want them to add up to?
