ADDO – Focus: To practise number facts to 20 Equipment: 2 sets of cards from 0 to 10. Gameboard – this is a simple 3x3 grid How to play: 1.
Separate the 2 sets of cards into 2 piles, making sure that each set has only one of each card. Fill the gameboard with numbers chosen from 1 to 20. Draw a card from each pile. Add the two numbers on the cards together e.g. 2 and 7 make 9. These cards are then placed apart from the 2 decks of unplayed cards. 5. If any player has a 9 on his/her board, he/she can cross it off. 6. Keep repeating steps 3 – 5 until the first player to have 3 in a row (across, down or diagonal) says “Addo!” 7. The game can stop there and restart with a new gameboard OR the game can continue till every number on the board has been crossed off. Discussion: 
What are the possible numbers to put on the gameboard? What are the numbers that will be possible? What are the best numbers to put on the board to make sure you win? GO FISH! Focus: To practise number facts to 20 Equipment: Playing cards Joker to 10 (no picture cards) – Joker is 0 Timer Number of players: 2 or more How to play: 1. Place all cards face up on the table. 2. Agree on a set time e.g. 1 minute and set the timer. 3. Player 1 then uses this time to pick up 2 cards that total 10 by saying out loud: 2 and 8 make 10, 3 and 7 make 10, etc. 4. When time is up, Player 2 has a turn with the same set time. 5. The game ends when no more pairs totalling 10 can be made and the Player with the most cards wins. VERSION 2: Practise other number facts by setting a different total each time e.g. pairs of cards that make 19. VERSION 3: 1. Set the timer for 1 minute and set a target total e.g. 2 cards that make a total of 12. 2. All players start to pick up pairs of cards when timer starts. 3. Game ends when all possible pairs of cards are picked up or all cards are gone. 4. Winner is the player with the most cards – but players must check that pairs DO add up to the set total or the pairs are forfeit. Got It!
This is a game for two players.
Start with the target number of 23.
The first player chooses a whole number from 1 to 4.
Players take turns to add a whole number from 1 to 4 to the
running total.
The player who hits the target of 23 wins the game.
Can you find a winning strategy?
Can you always win?
What happens if you choose a new target number?
What happens if you change the range of numbers you can add?
Can you work out a winning strategy for any target and any
range of numbers?
Mixing Lemonade
I mixed up some lemonade in two
The first glass had 60ml of lemon
juice and 200ml of water.
The second glass had 100ml of

The ROCKET Game Focus: To practise naming and ordering numbers Equipment: Dice (10‐sided dice) Paper Pencils Players: 2 or more How to Play: 1. Choose how many dice you will be using – 1 die for single digit numbers, 2 for 2‐digit numbers, etc. 2. Throw the dice and players choose to make a number to place on their rocket e.g. a 2 and a 3 can be 23 or 32. 3. Once a number has been placed on the rocket, it cannot be changed or moved to another level. 4. There are 5 levels on the rocket, so the dice is thrown 5 times. 5. The objective of the game is to place all numbers on the rocket from the smallest value at the bottom to the largest value at the top. 6. If a player is unable to place a number in the right place, he/she is out of the game. Tourism
