The Tower of Hanoi is an ancient mathematical challenge. Working on the building blocks may help you to explain the patterns you notice.
Charlie and Alison have been drawing patterns on coordinate grids. Can you picture where the patterns lead?
A mother wants to share some money by giving each child in turn a lump sum plus a fraction of the remainder. How can she do this to share the money out equally?
Can you guarantee that, for any three numbers you choose, the product of their differences will always be an even number?
Take any four digit number. Move the first digit to the end and move the rest along. Now add your two numbers. Did you get a multiple of 11?
Alison & Charlie explored how NRICH tasks can be used to develop students' reasoning and fluency through purposeful practice
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.
In this article for primary teachers, we suggest ways in which children's solutions on the NRICH site can be used as a teaching resource in their own right.
