Quick puzzles and problems
Sixes (The Storeroom)
Use four sixes and any mathematical operations to make the numbers from 1 to 10.
Transum (Starter of the Day)
Broken Calculator Flash application (Suffolk Maths)
Pupils work out how to input calculations into a broken calculator using BIDMAS. The file is a direct download and can be run without Internet connection.
Make 100 (NRich)
Use operation signs in between the digits 1, 2, 3, 4, 5, 6, 7, 8, 9 to make an answer of 100. Pupils could try and find more than one solution. There's a poster version available which may be useful to display on an interactive board.
