Strategy 1: Show Your Working

Your working = Your safety net

Even if you make a mistake, you can still get marks!

Example 1 - Question 7:

“Express 66 minutes as a percentage of 2 hours”

Show Your Working - Example 1

What many wrote (risky):

55%

Safer (writing your working):

Step 1: 2 hours = 120 min

Step 2: \(\frac{66}{120}\)

Step 3: = 0.55

Step 4: = 55%

Show Your Working - Example 2

Question 9:

“Jay gained 93% of 600 marks. How many more marks would he need to gain 96%?”

Risky

18 marks

Clear steps (much safer):

93% of 600 = 558 marks

96% of 600 = 576 marks

Difference = 576 - 558 = 18 marks

Mark your Learning Tracker for “Show working”

Your Turn - Show Working

Find ONE question where you didn’t show working. Fix it now.

Strategy 2: Question Hunt

Find what they’re ACTUALLY asking for!

Example 1 - Question 8:

“Example 1: A TV marked at $860 is discounted by 5%. Find the sale price.”

Question Hunt - Example 1 continued

❌ Common mistake:

5% of $860 = $43

(This is the discount, not the price!)

✓ What they wanted:

5% of $860 = $43

Sale price = $860 - $43 = $817

Question Hunt - Example 2

Question 5 (Percentages):

“Order from smallest to largest: 0.7, 3/4, 72%, 4/5”

❌ Common mistake:

4/5, 3/4, 72%, 0.7

(This is largest to smallest!)

✓ Read carefully:

0.7, 72%, 3/4, 4/5

(Smallest → Largest)

Your Turn - Question Hunt

Find a question where you misread what they wanted

  1. Write as you read the question:
  • Underline the data
  • Swiggly line under the question
  • Circle trap words
  1. Do your calculations, then check that you answered the question.

Strategy 3: Parts and Wholes

Question: “Joey and Chandler share lollies in the ratio 2:1. If there were 42 lollies, how many did Chandler get?”

The ratio 2:1 means:

Joey gets 2 parts

Chandler gets 1 part

Total = 3 parts

So:

3 parts = 42 lollies

1 part = \(\dfrac{42}{3}\) = 14 lollies

Chandler = 14 lollies

Parts and Wholes - Percentages

Question: “A phone costs $900 including 10% GST. Find the pre-GST cost.”

Key insight: “Including 10% GST” means the $900 is 110% of the original

$900 = 110% of original price
Original = $900 ÷ 1.1
        = $818.18

Your Turn - Parts and Wholes

Choose ONE to fix:

  • Question 5 (ratios) - Remember total parts
  • Question 10 (GST) - Remember: price = 110%

Show your working!

Strategy 4: Working Backwards

Start with the answer and work back!

Example - Question 6b:

“Shloom earns $35/hour. How long to earn $262.50?”

Working Backwards

Think: What number × $35 = $262.50?

Write it out:

hours × $35/h = $262.50

hours = $262.50 ÷ $35

hours = 7.5

Check it:

7.5 × $35 = $262.50 ✓

Mark your Learning Tracker for “Working backwards”

Your Turn - Working Backwards

Fix ONE of these using working backwards:

  • Question 6b (hours to earn $262.50)
  • Question 10 (pre-GST price)

Use the template and CHECK your answer!
