Understanding fractions (age 9+)
Mathematics · Mathematical Thinking · meta
Construct and present logical mathematical arguments involving multiple steps; critique others' reasoning about fractions, angles, or calculations and clearly explain errors or alternative methods
What mastery looks like
- 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
Check your understanding
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?
