Compare Bigger Unknowns: “More” version word problem: Tommy has 3 more points than Jaden. Jaden has 2 points. How many points does Tommy have?
2+3=p Unknown
Solve for the unknown: 2+3=p p=5
Compare Bigger Unknowns: “Fewer” version word problem: There are 3 fewer watermelons than apples. There are 8 watermelons. How many apples are there?
8+3=w Unknown
Considerations: Students benefit from experiencing many ways to represent the unknown (empty box, letters, symbols, etc.). Problems in this lesson prepare students to work with “more” and “fewer” problems. Both will be needed in the following lessons.
Steps: 1. Listen carefully to the numbers in the word problem. 2. Use the numbers to write an equation using a symbol or letter to represent the unknown. 3. Solve for the unknown.
Application of MPs: MP1:
What math symbol did you use today?
MP2: How do you know your answers are correct? MP7: What steps helped you solve the problems?
Solve for the unknown: 8+3=w w = 11
