Solve problems requiring two operations like library book scenarios through interactive problem-solving activities. Learn to break down complex problems into manageable steps.
Our classroom library had 50 books. Students borrowed 18 books, and then returned 12 books. How many books are in the library now?
Two-Step Problem Challenge
Master two-step problem solving through interactive activities and real-world scenarios
Step 1: Read the problem
Understand what you need to find
Step 2: Identify operations
What operations do you need?
Step 3: Solve first operation
Find the first answer
Step 4: Solve second operation
Use first answer for second operation
Problem:
50 books - 18 borrowed + 12 returned = ?
Step 1:
50 - 18 = 32 books left
Step 2:
32 + 12 = 44 books total
Answer:
44 books in library now
Store: 25 apples - 8 sold + 15 new = 32 apples
Class: 30 students - 5 absent + 3 new = 28 students
Piggy Bank: $20 - $7 spent + $12 earned = $25
Garden: 40 flowers - 12 picked + 18 new = 46 flowers
What do I know? Starting amount, what happened first, what happened second
What do I need to find? Final amount after both operations
What operations? Subtraction first, then addition
