You might like to start by investigating the patterns you get when you shade multiples of a number on a grid. Download here
For the prime sieve investigation use a 100 square grid (download here):
Circle the number 2. Put a line through every multiple of 2 up to 100.
[…]

Do your own experiments using number cards to play the games and pick 2 cards at random each time.
In Game A an envelope or bag contains balls, or cards, numbered 2, 3, 4, 5 and 6. Pick out two balls or cards at random. If the total is even you win. […]
It is not easy to find the factors of 2021, but here is a clue: use the fact that $3 \times 7 = 21$
You can be a creative mathematician, you can be someone who has your own mathematical ideas. Find your own interesting facts about 2021 and calculations that have the […]
A staircase has 12 steps. You can go down the steps one at a time or two at time.
For example:
You could go down 1 step, then 1 step, then 2 steps, then 2, 2, 1, 1, 1, 1 as in the picture.
In how many different ways […]
What patterns do you see in them?
Suppose you have to share 9872 gold coins between 8 people.
You give the coins out in thousands until there are less than 8000 left.
Then you give out one hundred at a time until there are less than 800, then […]
Another TARGET game for any number of players. You want to win? So THINK MATHEMATICALLY and ESTIMATE the likely answers. When you multiply H hundreds by T tens what do you want the product of the digits H×T to be? A bit less than 10 perhaps?
You will need a set of 10 cards […]
A game for any number of players. You want to win by getting the total close to 100, so THINK MATHEMATICALLY! Concentrate on the digits in the tens column. What do you want them to add up to?
You need a set of 10 cards numbered 0 to 9 or a spinner. […]
Another TARGET game for any number of players or for the whole class as a lesson starter. You want to win so THINK MATHEMATICALLY. To get near to the target of 1000 you must get the hundreds digit multiplied by the single digit number close to 10. So for those 2 digits […]
