What This Standard Means
What Students Need to Do
- Students choose tools that make a problem easier to solve or represent. They use each tool correctly and decide whether its output is reasonable.
What Mastery Looks Like
- Students select a tool that fits the problem and use it accurately. They explain their choice, interpret the result, and check whether the answer makes sense.
Common Misconceptions
- Students may grab a calculator for every problem or avoid tools even when they would help. They may trust a screen result without checking units, scale, or reasonableness.
How to Assess It
- Give students a scale drawing problem with a ruler, graph paper, and calculator available. Ask them to solve it and write why their chosen tool helped.
