Make some graphs to record the measurements that interest your child. Graph paper and felt pens are great. Kids can also make graphs online at

  • Heights of family members and friends—whoever will stand up and be measured. Use 1 square on the graph paper for every 20 cm in height, or 1 square for every 10 cm in height.

  • Show the height compared with the “wingspan” of a few people. Again, 1 square on the graph paper for every 10 or 20 cm.

  • Show the length of the foot compared with the distance from the wrist to the inside of the elbow of a few people. Use 1 square for 1 cm.
