Story: Golf is an Olympic sport? Well, now I've heard everything! Problem though - the scoring system is broken! You will have to add your end-of-round golf score yourself. I guess the organisers of the Olympics were too busy focusing on the real sports... :)
Tools:
Dice or playing cards to generate scores for the 9-hole golf course.
Golf score card (roll 9 dice into this repeatedly)
Recording template (showing your strategies)
Main event
With 9 dice (or playing cards), create your golf round scores.
Next, add your score.
Focus on using efficient addition strategies, including:
10 facts (code this: 10f, using shorthand codes to reduce literacy barriers for recording - see recording work samples below from students in year 2)
doubles and near doubles ('d' and 'nd')
building to 10 ('bt10')
Aim to avoid (wherever possible):
- counting all or counting on by ones
Pro tip: Create friendly pairs. For example, 8 and 2 are besties, because they join to make a 10 fact. 8 and 7 are pretty good mates, because they join to make a double + 1, or a double - 1.
Support: Focus mostly on 10 facts and collaboratively brainstorm a list of 10 facts at the start of the session that these students can refer back to on a post-it note on their desk.
Extension 1: Aim to use multiplication or near multiplication. For example, for example to add 5, 5, 6, 7, try 4 x 5 (4 fives + 3 to add the extra one from the 6 and extra 2 from the 7). Or average to 4 sixes take away 1 (4 x 6 - 1), because the 5 and 7 average to a 6, then take away 1 for the 5 that was not worth 6.
Extension 2: Calculate the mean, median, mode and range of your score.
