Can you find sets of sloping lines that enclose a square?
A collection of short problems on straight line graphs.
Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the red dot affects its vertical and horizontal movement at each stage.
On the graph there are 28 marked points. These points all mark the vertices (corners) of eight hidden squares. Can you find the eight hidden squares?
Graphs are a crucial tool in dealing with the data that science generates.
Can you find the area between this graph and the x-axis, between x=3 and x=7?
Can you solve the clues to find out who's who on the friendship graph?
Can you draw the graph of $y=x$ after it has been rotated $90$ degrees clockwise about $(1,1)$?
Who's closest to the correct number of sweets in a jar - an individual guess or the average of many individuals' guesses? Which average?
Which of these graphs could be the graph showing the circumference of a circle in terms of its diameter ?

Can you sketch graphs to show how the height of water changes in different containers as they are filled?
How could you use this graph to work out the weight of a single sheet of paper?
The graph represents a salesman’s area of activity with the shops that the salesman must visit each day. What route around the shops has the minimum total distance?
Make your own pinhole camera for safe observation of the sun, and find out how it works.
Alf Coles writes about how he tries to create 'spaces for exploration' for the students in his classrooms.
The water is being drained from a pool. After how long will the depth of the pool be 144 cm?
A Hamiltonian circuit is a continuous path in a graph that passes through each of the vertices exactly once and returns to the start. How many Hamiltonian circuits can you find in these graphs?
Resources from the first STEM TI day, September 2011.
What proportion of people make 90% confident guesses which actually contain the correct answer?
Alf and Tracy explain how the Kingsfield School maths department use common tasks to encourage all students to think mathematically about key areas in the curriculum.
This task requires learners to explain and help others, asking and answering questions.
This article looks at the importance in mathematics of representing places and spaces mathematics. Many famous mathematicians have spent time working on problems that involve moving and mapping. . . .

This short activity encourages students to consider a surprising result about the average number of friends that people have.
You may like to read the article on Morse code before attempting this question. Morse's letter analysis was done over 150 years ago, so might there be a better allocation of symbols today?
In this feature, we offer a selection of rich problems about area for use in all secondary classrooms.
