What This Standard Means
What Students Need to Do
- Students connect numbers and symbols to real quantities in a situation. They move between a story, a model, and an equation while keeping track of units and meaning.
What Mastery Looks Like
- Students write an equation or expression that matches a story, then connect the result back to the situation. They explain what each number and unit means and check whether the answer is reasonable.
Common Misconceptions
- Students may choose an operation just because they see certain numbers or words. They may drop units, use every number given, or give an answer that does not fit the situation.
How to Assess It
- Exit ticket: Six bags hold four apples each. Write an expression, solve it, label the answer, and explain what each number represents.
