If you know how to multiply and divide, you may enjoy these challenges.

How are you deciding where to put the digits?
Can you come up with a strategy for deciding where to place the digits so that you get as close as possible to the target in your first or second attempt?
If you are working away from a computer, you could treat this as a game for two people, or play in two teams of two.
Here are three examples of games you could play:
Game 1: target 1000Image
| Game 2: target 10000Image
| Game 3: target 1000Image
|
There are two parts to this game, whether you choose Game 1, Game 2 or Game 3, or a version of your choice. The first part involves an element of chance and the second part involves careful reasoning.
Find a partner and a 1-6 dice, or preferably a 0-9 dice if you have one.
Each player will need to draw a multiplication or a division grid that matches the game they've chosen. (Alternatively, there is a printable scoring sheet linked at the top of this page.)
Part 1
Throw the dice. Each player decides where to place that number in their own grid. Continue until all the cells are filled.
Whoever has the result closer to the target wins.
Part 2
This time, seeing the numbers thrown in part 1, each player decides where to place them on their own grid (as in the interactivity above).
Again, whoever has the result closer to the target wins.
There are two possible scoring systems for each part of the game:
- A point for a win. The first person to reach 10 wins the game.
- Each player keeps a running total of their 'penalty points', the difference between their result and the target after each round. First to 5000 loses.
These challenges follow on from Dicey operations and can be approached in a very similar way, so we suggest that you refer to the Teachers' Resources section of Dicey operations for appropriate guidance.
