Solution: Exercises 1 to 3
1 Basic Picture Subtraction
Exercise 1
Solve: 🍎🍎🍎🍎🍎🍎 - 🍎🍎 = ? using pictures within 10.
Definition:

Picture subtraction: Using visual representations to model and solve subtraction problems with numbers within 10.

Picture subtraction method:
  1. Count the initial set of pictures (within 10)
  2. Cross out the number of pictures being subtracted
  3. Count the remaining pictures
  4. The remaining pictures represent the answer
Initial Set
🍎🍎🍎🍎🍎🍎
Take Away
🍎🍎
Answer
🍎🍎🍎🍎
Step 1: Count 6 apples

Visualize: 🍎🍎🍎🍎🍎🍎 (total of 6 apples)

Step 2: Cross out 2 apples

Remove: 🍎🍎 (2 apples taken away)

Step 3: Count remaining apples

Count: 🍎🍎🍎🍎 (4 apples left)

Step 4: Record the difference

The answer is 4

6 - 2 = 4
Final answer:

6 - 2 = 4

Applied rules:

• Visual modeling: Represent numbers with pictures within 10

• Take away: Cross out the specified number of pictures

• Counting: Count the remaining pictures

2 Visual Model Method
Exercise 2
Solve: 🐱🐱🐱🐱🐱 - 🐱 = ? using visual models with pictures within 10.
Definition:

Visual model subtraction: Using drawings or pictures to represent the subtraction process with numbers within 10.

Initial Set
🐱🐱🐱🐱🐱
Take Away
🐱
Answer
🐱🐱🐱🐱
Step 1: Count 5 cats

Visualize: 🐱🐱🐱🐱🐱 (total of 5 cats)

Step 2: Cross out 1 cat

Remove: 🐱 (1 cat taken away)

Step 3: Count remaining cats

Count: 🐱🐱🐱🐱 (4 cats left)

Step 4: Record the difference

The answer is 4

5 - 1 = 4
Final answer:

5 - 1 = 4

Applied rules:

• Visual representation: Draw pictures to match numbers within 10

Initial Set
🌟🌟🌟🌟🌟🌟🌟
Take Away
🌟🌟🌟
Answer
🌟🌟🌟🌟
Step 1: Count 7 stars

Visualize: 🌟🌟🌟🌟🌟🌟🌟 (total of 7 stars)

Step 2: Cross out 3 stars

Remove: 🌟🌟🌟 (3 stars taken away)

Step 3: Count remaining stars

Count: 🌟🌟🌟🌟 (4 stars left)

Step 4: Record the difference

The answer is 4

7 - 3 = 4
Final answer:

7 - 3 = 4

Applied rules:

• Pattern recognition: Use familiar pictures to identify subtraction patterns

• Subtraction: Crossing out represents the "take away" action

• Counting: Count what remains to find the answer

📚 SUBTRACTION WITH PICTURES WITHIN 10 - COMPLETE SUMMARY

Definitions:

  • Picture Subtraction: Using visual representations to model and solve subtraction problems with numbers within 10
  • Visual Models: Pictures or drawings that represent mathematical concepts
  • Pattern Recognition: Identifying subtraction patterns using familiar pictures
  • Concrete Representation: Visual objects representing numbers within 10
  • Take Away: Removing pictures to find the difference

Core Rules & Principles:

  • Visual Modeling: Draw pictures to match the minuend (within 10)
  • Take Away: Cross out pictures matching the subtrahend
  • Counting: Count remaining pictures to find the difference
  • Verification: Always check by counting remaining pictures

Step-by-Step Methods:

  1. Draw Pictures: Create visual representations of the minuend (within 10)
  2. Mark Removal: Cross out pictures equal to the subtrahend
  3. Count Remainder: Count the uncrossed pictures
  4. Record Answer: The count is the difference
  5. Verify: Double-check by recounting

Examples (Simple to Advanced):

  • Simple: 🍏 - 🍏 = 0 (1 - 1 = 0)
  • Medium: 🐘🐘 - 🐘 = 🐘 (2 - 1 = 1)
  • Advanced: 🦋🦋🦋🦋🦋🦋🦋🦋 - 🦋🦋 = 🦋🦋🦋🦋🦋 (8 - 2 = 6)

Tips & Tricks:

  • Use Familiar Pictures: Draw things children recognize
  • Cross Out Clearly: Make it obvious which pictures are being removed
  • Organize Neatly: Arrange pictures in rows or groups
  • Count Aloud: Say the numbers while counting remaining pictures

Common Pitfalls:

  • Not crossing out the correct number of pictures
  • Counting crossed-out pictures as remaining
  • Forgetting to count the remaining pictures
  • Not organizing drawings clearly

Key Notes for Memorization:

  • Pictures help visualize the "take away" concept
  • Crossed-out pictures represent subtraction
  • The remaining pictures show the difference
  • Always verify by recounting

Questions & Answers

Question: My child draws messy pictures when doing subtraction with pictures and loses track of what's crossed out. How can I help them organize their work better?

Answer: Organization is key! Here are effective strategies:

  • Have them draw pictures in neat rows or groups of 5 or 10
  • Use a ruler to draw straight lines when crossing out
  • Teach them to make one clear X over each picture being subtracted
  • Have them count and label the pictures before starting (1, 2, 3, etc.)

Example: For 7 - 2, draw 7 pictures in a row, label them 1-7, then cross out pictures 1 and 2.

Neat organization prevents confusion and makes counting easier.

Question: When should I transition students from picture subtraction to abstract symbols?

Answer: The transition should be gradual and individualized:

  • Continue using pictures until students demonstrate consistent accuracy
  • Introduce symbols alongside pictures for familiar problems
  • Gradually reduce reliance on pictures while maintaining them as a backup
  • Allow students to choose their preferred method

Example: For 8 - 3, first solve with pictures, then write the number sentence 8 - 3 = 5.

Some students may need pictures for longer periods, which is perfectly normal.

Question: How can I help students who count crossed-out pictures as remaining?

Answer: This is a common misunderstanding! Address it with:

  • Clear demonstrations showing the difference between crossed and uncrossed pictures
  • Use different colors: one for total, another for crossed out
  • Have students point to and count only the uncrossed pictures
  • Practice with smaller numbers first to build understanding

Example: Use red for crossed pictures and blue for remaining ones to provide visual distinction.

Reinforce that crossed-out pictures are "gone" and should not be counted.
