Teacher's field guide

What Students Need to Do: Students write questions they can answer by asking people or checking objects. Their questions collect categories, such as ways to get to school, and numbers, such as minutes spent traveling.
What Mastery Looks Like: A student can ask, 'How did you get to school?' and 'How many minutes did the trip take?' They can tell what kind of answer each question will give and who they will ask.
Common Misconceptions: Some students treat a jersey number as an amount, though it is a label. Others write 'How many blue?' without naming what they want to count.
How to Assess It: Exit ticket: Write two questions to ask classmates, one that gives a category and one that gives a number. Give a possible answer to each.
