Strategy 1: Show Your Working

Your working = Your safety net

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

Let’s fix Question 7 together:

“Express 66 minutes as a percentage of 2 hours”

Show Your Working - Example

❌ What many wrote:

55%

✓ What gets marks:

Step 1: 2 hours = 120 min

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

Step 3: = 0.55

Step 4: = 55%


Mark your Learning Tracker for “Show working”

Your Turn - Show Working

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

Step 1: _____________
Step 2: _____________
Step 3: _____________
Answer: _____________

Strategy 2: Question Hunt

Find what they’re ACTUALLY asking for!

Let’s look at Question 8:

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

Question Hunt - The Trap

❌ 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 Rules:

  • Circle the actual question
  • Check: Am I finding the total or the difference?
  • Check: What units should my answer have?

Your Turn - Question Hunt

Find Question 8 on your paper

  1. Circle “sale price” in the question
  2. Fix your answer if needed
  3. Write: “I need to find the PRICE not the DISCOUNT”

Strategy 3: Parts and Wholes

See the TOTAL in ratios

Let’s fix Question 5 (Topic 2):

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

Parts and Wholes - Visual

Draw it to see it!

Joey:     ■■
Chandler: ■
Total:    ■■■ = 42 lollies

So: 3 parts = 42 lollies

1 part = 42 ÷ 3 = 14 lollies

Chandler gets 1 part = 14 lollies

Parts and Wholes - Percentages

“Including GST” means the price IS 110%

Question 10:

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

$900 = 110% of original price
Original = $900 ÷ 110 × 100
        = $818.18

Your Turn - Parts and Wholes

Choose ONE to fix:

  • Question 5 (ratios) - Draw the bars
  • Question 10 (GST) - Remember: price shown = 110%

Tip: When you see “including”, the amount given is MORE than 100%

Strategy 4: Working Backwards

Use algebra thinking!

Question 6b:

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

Working Backwards - Method

Think: What × $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 ✓

Your Turn - Working Backwards

Fix Question 6b using the template: 

What I know: _____ × $35/h = $262.50
So: _____ = $262.50 ÷ $35
Answer: _____ hours
Check: _____ × $35 = _____
