Add by Counting On - Sums up to 10
š Boost your addition speed! Instead of counting every single thing, start with the biggest number and just count on from there.
Concept
When adding two numbers together, you don't need to start from 1. šÆ **The "Count On" Trick:** If you want to solve **6 + 3**, you don't need to count 1,2,3,4,5,6... and then 7,8,9. 1. **Find the bigger number:** In 6 + 3, the bigger number is 6. 2. **Put that number in your head:** Think "6". 3. **Count on the smaller number:** Hold up 3 fingers. Say "6"... then put down a finger and say "7", "8", "9". 4. **The last number you say is the answer!** So, 6 + 3 = 9. This trick saves so much time! It also works even if the small number is first. For 2 + 7, start at 7 and count on 2: "7... 8, 9".
