Compare Smaller Unknown: “More” Version Word Problems: There are 3 more boys than girls. There are 9 boys. How many girls are there? 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 Compare Smaller V=6 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.
