01

What Students Need to Do

Students make sense of real situations and decide how mathematics can help. They choose strategies, tools, and representations to solve problems. They explain their reasoning, justify answers, and check whether solutions are reasonable.

02

What Mastery Looks Like

Students identify what is known, what is being asked, and which strategy or tool fits. They solve accurately and show their thinking with numbers, words, tables, or diagrams. They check the answer and explain why it makes sense.

03

Common Misconceptions

Students may choose an operation from a keyword without understanding the situation. They may accept the first answer without checking its size or units. Some use diagrams or tools without explaining how they support the solution.

04

How to Assess It

Give this exit ticket: “Four classes collect 128 cans each. How many cans do they collect, and how can you check your answer?” Require a plan, solution, representation, and reasonableness check.

1. 01

   Give pairs play money and store price cards, then have them plan purchases, calculate totals, and explain why their choices fit the budget.

2. 02

   Ask students to write which strategy they would use for a multistep problem and defend why it is more useful than another strategy.

3. 03

   Play Strategy Sort with problem cards, having teams match each card to estimation, a diagram, a table, mental math, or written computation.

4. 04

   Use a class party budget task where students compare package sizes, calculate costs, record choices in a table, and justify the final plan.
