Use your reasoning skills and your understanding of coordinates to find the robber in this online maths game, ‘Cops and Robbers’, from NRICH. There are 4 levels of the game to try. The hardest level will be a challenge. It is probably best to start with level 1 or 2 to get used to the game first and develop your skills at narrowing down the guesses. Click on the image of the game to go to the NRICH website and play.

Can you find the robber in less than five guesses? What is a good starting strategy? What is a successful strategy for your next guesses?

Here is a really good site to help you investigate shape. You can experiment with different quadrilaterals which will help you  to understand and remember their properties. It is also fun to change the angles and sides to see what difference this makes to the shape. There are other pages within this site that also allow you to look at the geometry of polygons other than quadrilaterals (including the graphic we saw some time ago where you can approximate a circle by adding in sides…). This is well worth having a look. Have fun with it!
