Problem of the Day
Objective: Today, I will solve “More” versions of comparing word problems
involving smaller unknowns.
Vocabulary
Teacher Resources
Compare Smaller Unknown – “More” version word problems: There are 3 more boys than girls. There are 9 boys. How many girls are there?
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.
9—3=V Unknown Solve for the unknown:
9—3=6 V=6 This problem can also be solved as a missing addend problem.
V+3=9 V=6

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?
