Reasoning About Numbers, with Challenges and Simplifications
This booklet from the National Numeracy Strategy was written to help students:
* solve mathematical problems or puzzles, recognise and explain patterns and relationships, generalise and predict;
* explain methods and reasoning orally and in writing;
* suggest extensions by asking ‘What if …?’
All the activities give ideas for simplifications and challenges.
[b]Handshakes[/b] investigates the number of handshakes if everyone in a room shakes hands with everyone else.
[b]24[/b] gives students the opportunity to find different questions that give the answer 24.
[b]Decigame[/b] is a game for two players using division of numbers to give an answer between zero and one.
[b]Snakes[/b] explores what number patterns are created when you half and double numbers.
[b]Consecutive sums[/b] explores the numbers you can make by adding consecutive numbers.
[b]Magic squares[/b] asks students to explore magic squares given certain rules.
[b]Getting even[/b] is a two-player game based on sum of two numbers created by the players.
[b]Different products[/b] explores the products students can make with given numbers.

[b]Ordering numbers[/b] ask students to create numbers using number cards and then order them.
[b]Arithmagons[/b] is a structure for students to practice addition and subtraction.
[b]Swapping places[/b] investigates the number of moves two colours of counters have to make to 'swap' sides.
[b]Bracelets[/b] asks students to create a 'bracelet' of numbers with appropriate number operations between the numbers.

Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our health and safety guidance.
