Games are a great way to keep your children's interest in this subject. Card games such as Salute and Stacker improve their basic facts addition and subtraction skills.

**Salute** is played by 3 players.
Face cards count as ten all others by their face value. One person is the caller and the two contestants sit facing each other with half of the pack of cards in front of each of them. They each draw a card simultaneously, on the word "Go", from their pile, away from themselves, and hold the cards on their foreheads so that only their opponent and the caller can see them. The caller calls out the total value of the cards and each of the players, being able to see his/hers opponents card, must deduct this from the total called to determine their card. The winner takes the winning cards and places them on the bottom of their pile. The winner is the person with more cards after a certain time limit. Face cards count as ten but these can be removed. The players split the pack between them and place them in front of each other. On the word "Go" they each turn a card away from themselves and place it on the ground. The first to give the correct total of the two cards takes them and puts them at the bottom of their pile. Again, the winner is the person with more cards after a certain time limit.
 * Stacker** is played by 2 players.

**Bowl A Fact**
In this game the numbers 1 to 10 are placed on a card or whiteboard just as they would in a bowling alley. 7 8 9 10 4 5 6 2 3 1 Three dice are thrown and their numbers are noted eg. 4, 3, 1 Students use these three numbers and as many as the four operations possible to eliminate as many as the numbers in the array and noting these. A time of 1 or 2 minutes to do this is allowed to make these calculations. The time can be reduced as the students proficiency increases. In the above case:- (4 - 3 ) * 1 = 1 4 - 3 + 1 = 2 3 -1 +4 = 6 3 * 1 + 4 = 7 4 + 3 + 1 = 8 (4 - 1) * 3 = 9 etc. and these facts are scored off the chart leaving 3, 4, 5 and 10 The next three dice are thrown and and subsequent numbers are marked off. This continues until the first person shouts "Strike" They should be able to justify all the numbers by reading out the operations and their values to a checker. Once players have had a strike their pins rise to 15 then 20 etc.

The WALT's for this page would be: Add numbers to 20 Subtract from a known total to find an unknown number (within 20) Using the four main operators in calculations.
