SF, Pencil, Paper, counters and base ten materials available
Provide materials to the student. Read the problem to the student: John collected 67 baseball cards. His friend gave him 28 more baseball cards. How many cards does John have now? Write an equation that represents this problem. Use a symbol for the unknown number.
Once an equation is written, say: Solve the problem and use words, numbers or pictures to explain your reasoning.
