What to Do:

  1. Show students the measurement tools you've assembled and explain how they are going to measure their hand in 4 different ways.
  2. Get the students to write a heading on the blank paper: “My Hand Size”. This will be the recording sheet. Divide the sheet into 4 sections and label them length, area, capacity, and volume.
  3. Measuring length: Use the paper clips to make a paper clip chain or use the tape measure to measure the length of your right hand. Start at the wrist and end at the tip of the longest finger. Count the number of paper clips or centimetres if using the measuring tape. Record the information on the recording sheet.
  4. Measuring Area: Use the graph paper for this portion of the activity. Help students place their right hand on the sheet of graph paper with their palm down and fingers closed. Tell them to trace around their closed hand with a pencil. Help the students count the number of squares their hand covers. Discuss a method for counting the partial squares. For example, if most of a square is covered does it count as one? Or can you combine 2 half squares to make one whole square? Record the information on the recording sheet.
  5. Measuring Capacity: Fill one small bowl with beans. Tell the students to pick up a handful of beans and see how many they can hold in their right hand without dropping any. Have the students empty the beans into the empty bowl and count them to find out their hand's capacity, or how many beans can they hold in their right hand. Record the information on the recording sheet.
  6. Measuring Volume: Place some water in the glass jar and mark the water line with a piece of masking tape. Tell the students to use their right hand to make a fist. Have them submerge their fist into the water up to their wrist and record the new water line with masking tape. The amount of water between the two lines is a measure of the volume of their fist. Try pouring this amount into a measuring cup to see the volume of your students' fist. Record the information on the recording sheet.
  7. Encourage the students to reflect on the activity by writing down their observations on a sheet of paper after making the four measurements of their hand.
For a challenge, the students can measure their left hand and make comparisons. Are the measurements the same for both hands? You can also encourage students in higher grades to do this at home with a family member. Then they can compare the results. Did their family member have a larger, smaller, bigger hand size capacity to them?
