### Consecutive Numbers

An investigation involving adding and subtracting sets of consecutive numbers. Lots to find out, lots to explore.

### Roll These Dice

Roll two red dice and a green dice. Add the two numbers on the red dice and take away the number on the green. What are all the different possible answers?

### Maze 100

Can you go through this maze so that the numbers you pass add to exactly 100?

# Poly Plug Rectangles

##### Age 5 to 14 Challenge Level:

This activity has been inspired by Doug Williams' Poly Plug resource.  You can find out more details, including how to order sets of Poly Plug, on the Mathematics Centre website.  However, you do not need sets of Poly Plug to have a go at this activity - please see below and take a look at the Teachers' Notes.

In this activity, the monkey secretly makes a rectangle using equal rows of spots on the $5$ by $5$ grid.

The aim is for you to find the rectangle by testing spots on the interactivity below.

Once you think you know where the monkey's rectangle is, click the 'Ready' button.

Which spot is a good one to test first?  Why?

If you had to use as few test spots as possible, how would that change the way you play?

Are there some total numbers of spots that are easier than others?

We would love to hear about the strategies you use for finding the monkey's rectangle.
