Steps to show subtraction with pictures for first graders

📚 What is Subtraction with Pictures?

Subtraction with pictures is a way to understand taking away using visual representations. Instead of just seeing numbers, you see objects, which can make subtraction easier to grasp. It's especially helpful for first graders who are just learning about numbers and how they work! This method connects abstract math to something concrete and visible.

📜 A Little History

Using pictures to teach math concepts has been around for a long time! Ancient civilizations used drawings to represent numbers and solve problems. Think about the Egyptians and their hieroglyphics or the Mayans with their number systems. While they weren't teaching first-grade subtraction, the idea of visualizing math is an old one.

⭐ Key Principles of Picture Subtraction

• 🍎 Representation: Use drawings to stand for numbers. For example, three apples can represent the number 3.
• ➖ Taking Away: Cross out or erase the number of pictures you are subtracting.
• 🔢 Counting Remaining: Count the pictures that are left to find the answer.
• ➕ Visual Connection: Connect the pictures to the written subtraction problem to show how they match.

✏️ Steps to Show Subtraction with Pictures

• 🖼️ Draw the Initial Amount: Draw a picture representing the first number in the subtraction problem (the number you are starting with). For instance, for $5 - 2$, draw 5 stars.
• ❌ Subtract by Crossing Out: Cross out the number of pictures that you are subtracting. In the example of $5 - 2$, cross out 2 of the stars.
• 💯 Count What's Left: Count the pictures that are not crossed out. The number of remaining pictures is your answer. In our star example, 3 stars are left, so $5 - 2 = 3$.
• ✍️ Write the Answer: Write the number that represents the remaining pictures as the answer to the subtraction problem.

💡 Real-World Examples

Example 1:

Problem: $4 - 1 = ?$

1. Draw 4 circles: O O O O
2. Cross out 1 circle: O O O O
3. Count the remaining circles: 3
4. Answer: $4 - 1 = 3$

Example 2:

Problem: $6 - 3 = ?$

1. Draw 6 triangles: △ △ △ △ △ △
2. Cross out 3 triangles: △ △ △ △ △ △
3. Count the remaining triangles: 3
4. Answer: $6 - 3 = 3$
