Knowing different number properties is an important skill. Along with good systematic reasoning, this is an engaging task for pair or group work. This cut, sort and stick activity allows students to discuss different properties of numbers (odd, even, prime, square, cube, fibonacci, factors and multiples) and work together to find all possible solutions.

Contents

• One 3 x 3 Grid which is suitable for both sets of cards.
• Two sets of question cards (with 9 cards in each set).
• Solutions: the possible placements of all the cards and all solutions which put a single card in each of the nine spaces to complete the grid.

Suggested use:

For this task, students cut out the question cards and sort them in the grid according to different number properties before sticking them down.

Students should be familiar with the following to be able to complete the task: odd & even numbers, inequality symbols (greater than), square and cube numbers, factors and multiples, prime numbers and the Fibonacci sequence

Differentiation

A great extension to this task is to ask students to create their own set of numbers which give only one possible solution for the given grid.

For support you could give students definitions of the key terms (odd, even, prime, multiple, factor, inequality symbols, square, cube and what the Fibonacci Sequence is).
