You and your child can invent measuring games, using an item, such as a toy or spoon as the “ruler.” Go around the house, measuring objects by length and/or height with the item. Use the terms as long as, longer than, shorter than, as tall as, and taller than.
As your child becomes more comfortable with the measuring, encourage him or her to use measuring in play as well as when involved in other family events. You may wish to make long-lasting memories of your child's growing height somewhere in your home. Show your child the numbers on the ruler or tape measure after you have marked the measurement. It will be fun to see the changes as time goes on.
