What This Standard Means
What Students Need to Do
- Students sort out what they know, what they need to find, and which information matters. They choose a method, solve, explain their reasoning, and check whether the result makes sense.
What Mastery Looks Like
- A student can mark the useful facts, state the unknown, and choose a sensible strategy. The student shows clear work, explains why the answer fits, and checks it another way.
Common Misconceptions
- Students may grab every number in the problem and start calculating before deciding what the question asks. They may accept an answer without checking units, size, or whether it fits the situation.
How to Assess It
- Give this exit ticket: “A $48 backpack is 25% off. What is the sale price?” Students must show a plan, solve, justify, and check.
