In December 2012, the Advisory Committee on Mathematics Education (ACME) published a report entitled Raising the Bar: Developing Able Young Mathematicians. The activities in this collection have been selected because they are particularly good for stimulating those children who might already be high attaining. They encourage deep mathematical thinking by offering contexts
in which to conjecture and generalise. Before taking a look at the tasks themselves, read Lynne's article which gives an overview of the ACME paper.
ACME Report: Developing able young mathematicians
Plants
Halving
These pictures show squares split into halves. Can you find other ways?
Stop the Clock
This is a game for two players. Can you find out how to be the first to get to 12 o'clock?
Ip Dip
"Ip dip sky blue! Who's 'it'? It's you!" Where would you position yourself so that you are 'it' if there are two players? Three players ...?
Cubes
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?
Got It
A game for two people, or play online. Given a target number, say 23, and a range of numbers to choose from, say 1-4, players take it in turns to add to the running total to hit their target.
