Understanding fractions (age 9+)
Construct and present logical mathematical arguments involving multiple steps; critique others' reasoning about fractions, angles, or calculations and clearly explain errors or alternative methods
Suggested ages 9–10
Learning journey
Your child is developing advanced problem-solving skills, learning to choose the best mathematical tools and methods for complex problems, and communicating their mathematical reasoning clearly.
Evidence of understanding
- Prove that 3/4 > 2/3 using a common denominator argument and a visual model
- Find and explain an error in a long multiplication where a partial product was misaligned
- Present a chain of reasoning to show that angles in a triangle sum to 180° by tearing and arranging
Assessment prompt
If Understanding fractions (age 9+) and a classmate solve the same maths problem differently, can Understanding fractions (age 9+) compare the two approaches, explain which method is more efficient, and identify any errors in either working?
