Pre-algebra word problems | Lesson
What are pre-algebra word problems?
Pre-algebra word problems are questions that require translating sentences to expressions, then evaluating those expressions.
The expressions we need to write will involve numbers and operations, but no variables.
What skills are tested?
- Solving real world problems by identifying relevant numbers and operations
- Identifying contexts where the answer must be rounded up or down
How do we solve pre-algebra word problems?
Solving pre-algebra word problems requires us to create expressions and evaluate them.
To solve a pre-algebra word problem:
- Identify the quantity to be calculated.
- Determine the operations and numbers needed to calculate the desired quantity.
- Write and evaluate the expressions to get the desired quantity.
- If the context requires rounding, round the answer.
