Compare Smaller Unknown – “Fewer” version word problems: There are 4 fewer basketballs than jump ropes. There are 10 jump ropes. How many basketballs are there?
10 — 4 = W Unknown Solve for the unknown:
10 — 4 = 6 W=6 This problem can also be solved as a missing addend problem.
W + 4 = 10 W=6

Considerations: Students need to be exposed to many ways to represent the unknown (empty box, letters, and symbols). This type of word problem can be solved as a subtraction equation or a missing addend equation.
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: MP2: What math symbol can you use today? MP6: How do you know your answers are correct? MP7: What steps help you solve the problems?
