Understanding Doubles Facts: 10 = ? + ?
Doubles facts are a simple yet powerful concept in math that help young learners master basic addition. A doubles fact occurs when both numbers in an addition problem are the same. In this post, we’ll focus on the doubles fact for the number 10 and walk through the process of solving it.
What is a Doubles Fact? A doubles fact is an addition problem where both numbers being added are identical. For example, the doubles fact for 4 is: 4+4=84 + 4 = 8 This means we are adding two equal numbers together to get the sum. Understanding doubles facts helps kids become more comfortable with addition and mental math.
Solving the Doubles Fact for 10: Let’s solve the doubles fact for the number 10. We are looking for two numbers that add up to 10, and both numbers must be the same.
- Start with the number 10.
- Think about how you can split 10 into two equal parts. Since the two numbers must be the same, divide 10 by 2: 10÷2=510 \div 2 = 5
- This means the two equal parts are 5. Therefore, the doubles fact for 10 is: 10=5+510 = 5 + 5
Conclusion: The doubles fact for 10 is 5 + 5 = 10. By practicing doubles facts like this one, students can build a strong foundation in addition and improve their math skills!
