Session 3/4/5

Learning Intention:  We are learning to calculate percentage discounts of 10%, 25%, and 50%

Success Criteria:

• I can convert 10%, 25%, and 50% to decimals.
  
  

• I can calculate the discount amount on items using these percentages.
  
  

• I can determine the final price after discount and explain the process using both mental calculations and digital tools.

Activity 

Board work, created by teacher

Students explore a mock online toy catalogue with items priced between $20 and $80. For each:

1. Convert 10%, 25% and 50% to 0.10, 0.25 and 0.50
   
   

2. Calculate discount = price × decimal equivalent, first by hand then verify with a calculator
   
   

3. Determine sale price and present their findings in table form.
   
   

Extension

Give students “mystery” price tags (e.g. $47, $63) and ask them to calculate 25% off mentally using rounding strategies, then check with digital tools
