ADDITION AND SUBTRACTION<br />

STRATEGIES<br />

To solve addition and subtraction sums, partition the numbers according to place value by<br />

visualising place value blocks or number expanders. <strong>The</strong>n add/subtract the numbers in each place.<br />

Remember to trade if required.<br />

When partitioning a subtraction sum, each<br />

place is subtracted and the answers are<br />

added together.<br />

10 Yes or No? Is this<br />

working out correct?<br />

294 – 163 = (200 – 100) + (90 – 60) + (4<br />

shape has internal reflex<br />

angles.<br />

Statistics and Probability — Chance<br />

Rock, paper, scissors<br />

Rules: Children on the count of three make a<br />

hand signal for rock, paper or scissors. Rock beats<br />

scissors; scissors beats paper; and paper<br />

beats rock.<br />

Draw straws<br />

Rules: One child holds enough straws for all<br />

players to have one each, hiding their length.<br />

One straw must be cut shorter than all the others.<br />

Players draw one straw randomly. <strong>The</strong> player with<br />

the shortest straw loses.<br />

Roll a dice<br />

Rules: All players roll<br />

a dice. <strong>The</strong> player<br />

with the highest<br />

number wins.<br />

Rock, paper, scissors<br />

Coin flipping<br />

Rules: One child flips a coin and the other child<br />

guesses if it will land heads up or tails up.<br />

Think of a number<br />

Rules: One child thinks of a mystery number<br />

between two given numbers. Players guess a<br />

number in that range. <strong>The</strong> player with the closest<br />

number to the mystery number wins.<br />

13 A child is thinking of a number<br />

between 1 and 20 inclusive. What is<br />

the probability of selecting the correct<br />

number?<br />

(a) 100%<br />

(b) 20%<br />

(c) 5%<br />

14 A child is thinking of a number<br />

between 1 and 8 inclusive. <strong>The</strong><br />

probability of selecting the correct<br />

number is:<br />

(a) 0.8 (b) 0.10 (c) 0.125<br />

15 True or False?<br />

<strong>The</strong> greater the range of numbers,<br />

the greater the chance of selecting the<br />

correct mystery number.<br />

16 Select the statement which justifies<br />

which game has more chance of<br />

winning—Coin flipping or Roll a dice.<br />

(a) Coin flipping has more chance of<br />

winning because it only has two<br />

choices available.<br />

(b) Roll a dice has more chance of<br />

winning because it has more<br />

numbers to choose from.<br />
