It was a dull Monday afternoon and I was in a dissecting mood. Using different colours I split each of the outlines below into 3 congruent shapes.
Your challenge is to work out how I did it (click the help tab above for more).

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College: "Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson. Keep up the good work" Comment recorded on the 1 February 'Starter of the Day' page by Terry Shaw, Beaulieu Convent School: "Really good site. Lots of good ideas for starters.

Numeracy"Numeracy is a proficiency which is developed mainly in Mathematics but also in other subjects. It is more than an ability to do basic arithmetic. It involves developing confidence and competence with numbers and measures. It requires understanding of the number system, a repertoire of mathematical techniques, and an inclination and ability to solve quantitative or spatial problems in a range of contexts. Numeracy also demands understanding of the ways in which data are gathered by counting and measuring, and presented in graphs, diagrams, charts and tables."

Go MathsLearning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those.

See the National Curriculum page for links to related online activities and resources.
Click a paint tin then click a square in one of the outlines to change its colour.
Your objective is to split the area inside the outline into a number of congruent shapes. So, for example if this is the outline given:
The congruent shapes could be shown using the colours like this:
Notice that each of the coloured shapes are congruent.
For each outline there may be a number of different ways to fill it with congruent shapes. You need to find the way I did it to be marked correct. You can have as many different attempts as you want (use the clear button to start again). The colours don't matter, you do not need to choose the same colours as I did. It is just the shapes that need to be correct.
You can learn more about the concept of congruent shapes by doing the Congruent Triangles exercise.
