Step-by-Step Guide to Near Doubles Addition

Near Doubles Addition: A Step-by-Step Guide ➕

Near doubles addition is a strategy that leverages the knowledge of doubles facts to quickly solve addition problems where the addends are close to each other. This method enhances mental math skills and provides a faster alternative to traditional addition.

Step 1: Identify Near Doubles 🤔

First, recognize that the two numbers you are adding are close to each other. For example, in 6 + 7, the numbers 6 and 7 are near doubles since 7 is just one more than 6.

Step 2: Use the Doubles Fact 💡

Choose the smaller number and double it. In the example 6 + 7, double 6, which equals 12.

6 + 6 = 12

Step 3: Adjust for the Difference ➕

Since you doubled the smaller number, you need to add the difference between the larger number and the smaller number to your result. In this case, the difference between 7 and 6 is 1. Add 1 to 12.

12 + 1 = 13

Step 4: State the Answer ✅

Therefore, 6 + 7 = 13.

Example 2: 8 + 9 🚀

1. Identify near doubles: 8 and 9 are near doubles.
2. Use the doubles fact: $8 + 8 = 16$.
3. Adjust for the difference: $16 + 1 = 17$.
4. State the answer: $8 + 9 = 17$.

Example 3: 15 + 16 🎯

1. Identify near doubles: 15 and 16 are near doubles.
2. Use the doubles fact: $15 + 15 = 30$.
3. Adjust for the difference: $30 + 1 = 31$.
4. State the answer: $15 + 16 = 31$.

Benefits of Using Near Doubles 👍

• Improved Mental Math: Encourages quick mental calculations.
