Introduction to Algebraic Thinking: Missing Numbers
Students will solve simple equations with a missing addend or subtrahend using inverse operations.
Key Questions
- Explain how addition can help us find a missing number in a subtraction problem.
- Design a strategy to find the unknown in a number sentence like '15 + ? = 23'.
- Justify why using a balance scale helps understand equations.
