Corrected sentences:
Your pulse is the beat of your heart that you can feel in your wrist and neck. A child's heart beats 80–100 times a minute.
What this means and how to check your pulse (easy steps):
- Pulse is the same as your heartbeat — you can feel it.
- To find it, use your index and middle fingers (not your thumb).
- Press gently on the inside of your wrist (on the thumb side) or on the side of your neck next to the windpipe.
- When you feel taps, count how many you feel in 15 seconds. Then multiply that number by 4 to get beats per minute.
- If you are running or playing, your pulse will be higher; when you are resting, it will be closer to 80–100 beats per minute.
Note: I only corrected the grammar and kept the same number range you wrote (80–100). If you want, I can also update the number to a typical range for a 7-year-old (resting rates can vary).
