Key Points to Remember

Essential concepts to master this topic
  • Rule: Addition combines quantities to find the total amount
  • Technique: Count forward from the first number: 6 + 7 = count 7 more from 6
  • Check: Verify by counting backwards: 13 - 6 = 7 ✓

Common Mistakes

Avoid these frequent errors
  • Counting the starting number twice
    Don't start counting from 6 and count '6, 7, 8...' = this gives 12! This counts the first number as part of the addition. Always start counting from the next number after 6: '7, 8, 9...'

FAQ

Everything you need to know about this question

Why do I keep getting 12 instead of 13?

+

You're probably counting the starting number as part of your count! When adding 6 + 7, start at 6 and count forward 7 more: 7, 8, 9, 10, 11, 12, 13.

Is there a faster way than counting?

+

Yes! You can memorize addition facts or use tricks like making 10: 6+7=6+4+3=10+3=13 6 + 7 = 6 + 4 + 3 = 10 + 3 = 13

What does 'units' mean in this problem?

+

Units just means individual items or objects. Whether it's 6 apples + 7 apples or 6 blocks + 7 blocks, you're still adding 6 + 7 = 13.

How can I check if my answer is right?

+

Try subtraction! If 6 + 7 = 13, then 13 - 6 should equal 7, and 13 - 7 should equal 6. Both work, so your answer is correct!

Can I add the numbers in a different order?

+

Absolutely! Addition is commutative, which means 6 + 7 gives the same answer as 7 + 6. Both equal 13!
