Expanding Single Brackets
Expand (multiply out) a single term over a bracket using the distributive property, e.g., 3(2x + 5) = 6x + 15; expand expressions involving negative multipliers
Suggested ages 11–13
Evidence of understanding
- Multiply a single positive term over a bracket to expand the expression
- Multiply a negative term over a bracket, correctly handling signs
- Combine expanding brackets with collecting like terms to simplify fully
Assessment prompt
Can Expanding Single Brackets expand a bracket like 3(2x + 5) by multiplying everything inside, to get 6x + 15?
