1. Factors & Multiples Mystery Grids
Students must use clues to work out the missing numbers in the grid. Example clues are: 'The number in the top right is a factor of all the numbers in the grid' and 'The number in the top right is a square number and a cube number'. Includes 3 different puzzles.
2. Special Numbers Activity Pack
This includes three different activities for more varied practice:
a. Number Puzzles: I'm thinking of a number, can you work out what it is? Students use clues such as 'My number is a prime number and a factor of 51' to work out a set of number puzzles.
b. Factors & Multiples Two Way Table: Students have to work out where the numbers go to complete the two way table.
c. Special Number 4 in a Line Game: Playing in pairs, students have to choose a card such as 'An Even Square Number'. They then find an example of their card on a grid of numbers and claim it. The first person to get four squares in a row, wins.
3. Prime Numbers & Composites Puzzles
These puzzles are about different ways of writing a number. Students must fill all the circles with prime numbers and the squares with composites (non-primes). Sets students up nicely for thinking about prime factorisation later on.
It's good to leave some feedback.

Top Stuff - the challenge at the end is great And challenging for all!!
These are good activities for students aged 14-15 who have forgotten these basics
