4 Two-Step Problem
Exercise 4
๐ŸŽ A farmer has 6 baskets. Each basket has 9 apples. If he sells 25 apples at the market, how many apples does he have left? This demonstrates multi-step problem solving with real-world application.
Lesson Objective:

Students will learn to: Solve multi-step word problems, identify the sequence of operations, and apply problem-solving strategies to real-world scenarios.

Step 1
6 ร— 9 = 54
Step 2
54 - 25 = 29
Step 1: Find the total number of apples

Number of baskets ร— Apples per basket = Total apples

6 ร— 9 = 54 apples

Step 2: Subtract the apples sold

Total apples - Sold apples = Apples left

54 - 25 = 29 apples

Step 3: Verify your answer

Apples left + Sold = Total: 29 + 25 = 54 โœ“

First: 6 ร— 9 = 54, Then: 54 - 25 = 29
Final answer:

The farmer has 29 apples left.

Multi-Step Rule:

๐Ÿ“š First: Complete the multiplication to find the total

๐Ÿ“š Then: Complete the subtraction to find what remains

5 Division with Remainder
Exercise 5
๐Ÿ• There are 31 pizza slices to share equally among 5 children. How many slices does each child get? Are there any slices left over? This teaches remainder interpretation in real contexts.
Lesson Objective:

Students will learn to: Solve division problems with remainders, interpret remainders in real-world contexts, and explain their reasoning.

Division
31 รท 5
Quotient
6
Remainder
1
Step 1: Set up the division

31 รท 5 = ?

Step 2: Find how many times 5 goes into 31

5 ร— 6 = 30, which is less than 31

5 ร— 7 = 35, which is more than 31

So 5 goes into 31 six times

Step 3: Find the remainder

31 - 30 = 1 slice left over

Step 4: Verify your answer

(5 ร— 6) + 1 = 30 + 1 = 31 โœ“

31 รท 5 = 6 R 1
Final answer:

Each child gets 6 slices, and 1 slice is left over.

Remainder Rule:

๐Ÿ“š Division algorithm: Dividend = (Divisor ร— Quotient) + Remainder

๐Ÿ“š Remainder interpretation: The amount left over that cannot be distributed equally
