Up to 100
You need two dice. You are aiming to make exactly 100, or get as close as you can. Take it in turns to throw the dice (or 1 die twice). Arrange the digits to make a number, e.g. if you throw a 2 and a 6 you could make 26, 62 or just use 2 or 6 on their own. Each time it is your go, throw the dice and then look at your running total to decide what number to make to add on to get closer and closer to 100. But you mustn't go above it. A player can say "Stick" at any time and keep their total. The total that is closest to 100 (without going over) wins. Your scores might look like this:

 Rolled Number made Running total 1, 2 21 21 3, 1 31 52 1, 4 41 93 3, 5 5 98

Encourage children to say the numbers that they make out loud.The game demands that players estimate additions as they go along to make the best use of their dice scores.

Thinking thousands
The game is played in the same way as Up to 100, but use three dice instead of two and try to get your total as close to 1000 as possible.

But a penny more, but a penny less
Take a shopping receipt - the longer the better! If the first item were 1p more, the second item 2p more, the third item 3p more etc. how much would each item cost? How much would the total bill now be? What is the difference between the new total and the actual bill?

Repeat for the first item 1p cheaper, second item 2p cheaper etc. How much does each item cost now? Are any items free? (That would happen if, for example, the twenty-third item cost 23p.) Would the shop be paying you to take items away? (That would happen if the position in the list were a higher number than the price of the item, for example, a tin of beans costing 28p were thirty-second on the list.)
