1. Quick Quiz
2. Play 25:
In this game, every black card represents a positive number. Every red card represents a negative number. In other words a black seven is worth +7 (seven), a red three is worth -3 (negative 3).
1. With your group, decide if you are going to use face cards (J= 11, Q = 12, K = 13) or not.
2. One student deals all the cards, so that each student has an equal number.
3. Each player places cards in a stack, face down.
4. The player to the right of the dealer flips their top card and places it in the centre, saying the number on the card. For example, if the player turns up a black eight, he or she says 8.
5. Continue from one player to the next in a clockwise direction. The second player turns up a card, adds it to the first card, and says the sum of the two cards aloud. For example, if the card is a red 9, which has a value of -9, the player says 8 + (-9) = (-1)
6. The next player takes the top card from his or her pile, adds it to the first two cards, and says the sum.
For example, if the card is a black 2, which has a value of +2, the player says (-1) + 2 = 1.
7. The game continues until someone shows a card that, when added to the stack, results in a sum of exactly 25.
(At different times during the game I will let you know to swap to subtraction instead of addition!)

Molly & Erika
Ashlee & Kya
Jayden & Lachlan
Alyssa & Grace
In pairs - roll three dice to make a decimal number each, like: 7.25 and 8.16.
Both of you then complete the ADDITION sum in your Maths book, then check to see if you got the same answer.
STOP AND CHECK: is this logical? Can you explain why?
If you think you got it wrong, try and work out why then have another go! 😊
After completing 5 addition sums correctly, move on to subtraction sums... Remember to put the larger number on top!
