What This Standard Means
What Students Need to Do
- Students find how much of one quantity goes with one unit of another. They say the result with both units, such as 3 apples per basket.
What Mastery Looks Like
- Given 12 apples packed equally into 4 baskets, a student says 3 apples per basket. They explain that each basket holds 3 apples.
Common Misconceptions
- Students may divide in the wrong order and say 4 apples per basket. They may say '3 per' without naming apples or baskets.
How to Assess It
- Exit ticket: A pack of 10 pencils costs $2. How much does one pencil cost? Write a sentence using 'per pencil.'
