Measuring Length in Second Grade.
According to Common Core site, here are some of the math standards that US second graders should be able to meet:
- Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
- Estimate lengths using units of inches, feet, centimeters, and meters.
- Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.
Does it sound boring? Not when you have your students measuring a fascinating subject - themselves!
Human Body Math Book
When Smarty was in preschool, I stumbled upon From Head to Toe book from I Love Math series during the library book sale. This book is perfect for kids from kindergarten to about second grade and has a lot of interesting activities and riddles that link math to human body. Our activity below was inspired by this book. Yes, we did it when Smarty was not yet in school, but she was (and still is) quite a few years ahead when it comes to comprehending math. I was hoping to entice her to repeat this project now, but she was too busy with a good book and did not want to cooperate with me, so I have to use lame pictures from that first time.
- A ruler and a measuring tape
- Gift wrap ribbons or yarn
- A willing child (one or more)
Engage in Creative Problem Solving
Ask your child, What's longer - your foot or your hand? How can you find out? Is your neck thicker than your thigh? How can you find that out? Hopefully, your child or children will come up with creative ways of measuring the length of their hand and feet and circumference of their necks and thighs, especially if they had an experience (not as frequent nowadays) of being measured with a measuring tape.
Help Kids Measure Themselves
Help your children measure different body parts by stretching or wrapping a piece of yarn and ribbon around the body part. Supervise this activity and help them cut the ribbon or yarn. Then they can straighten the ribbons and use the ruler to measure the results in inches and/or centimeters. Your student can also compare different body parts against each other - Smarty was fascinated to see how her hand was so much smaller than her foot.
Make a Human Body Poster
An original activity in From Head to Toe book recommended using stiff cardboard for pieces and building a primitive skeleton with them, but we went with an easier approach of a poster where we labeled different parts. Smarty predicted that her "big bottom" would be the biggest measurement we took, and she was right, but her big head came close second. It would be interesting to see how her body ratio compares now when she is 9 to what it was when she was 4. Perhaps I will convince her to investigate this question, after all :)
Bonus Human Body Math Activity
Are you a square or a rectangle? Smarty loved this "math+art" activity that I described in a guest post for Bedtime Math blog. All you need is some chalk and a measuring tape to answer this burning question!
