Have a go at creating these images based on circles. What do you notice about the areas of the different sections?
An equilateral triangle rotates around regular polygons and
produces an outline like a flower. What are the perimeters of the
L triominoes can fit together to make larger versions of
themselves. Is every size possible to make in this way?
The NRICH Stage 5 weekly challenges are shorter problems aimed at Post-16 students or enthusiastic younger students. There are 52 of them.
Mathmo is a revision tool for post-16 mathematics. It's great installed as a smartphone app, but it works well in pads and desktops and notebooks too. Give yourself a mathematical workout!
Make a catalogue of curves with various properties.
Get started with calculus by exploring the connections between the
sign of a curve and the sign of its gradient.
Find curves which have gradients of +1 or -1 at various points
The black box was cracked by several solvers in a great show of
ingenuity and determination.
Go to last month's problems to see more solutions.
Weekly challenges are here for NRICH! To celebrate this event,
we've collected a set of 20 essential problems for you to try.
What are rich tasks and contexts and why do they matter?
This task develops knowledge of transformation of graphs. By
framing and asking questions a member of the team has to find out
which mathematical function they have chosen.
