 Rounding to the nearest ten.
 Choosing appropriate operation symbols.
Game Overview
This game provides a number of options:
Odd and even
This game offers numbers up to 100 and asks children to identify whether they are odd or even. Where children are unsure, they can use the help button, which provides a visual image of the number, broken into recognisable units. When children use this online help, ask them to say how the number is represented.
More or less
Children are presented with pairs of numbers up to 100 and asked to identify whether the first is greater than, or less then the second. The True/false buttons selects the answer and children may need support initially in using these.
Win the Money
The screen shows a collection of coins and the player is asked to find the total value of the coins. It may be helpful to have a collection of coins or a number line to support children in their calculations.
Missing signs
This game can be played at different levels: addition and subtraction, multiplication and division or all four operations. Number sentences are presented with the operation sign missing. The player is asked to choose the appropriate operation symbol.
Round to the nearest 10p.
The game is played in two steps, with the child first finding the total, then rounding up or down. It works with the convention that any number ending in 04 is rounded DOWN to the previous 10p and any 59 is rounded up to the next 10p.
If children have difficulties in counting the larger piles of coins, they can use the cursor to count the coins individually as it highlights each coin one by one. Encourage the children to use known facts about one pile of coins to make intelligent judgements about the other piles. (E.g. if you have counted one pile and found it to be 80p, then the shorter pile cannot be 90p).
If playing the game in Netscape you will need Flash Player 4.020 or above, in order to print out the results. There is an option to upgrade your Flash as you access each game.
