Fizzy's Lunch Lab 2012: Measuring with Mixie-Bot

What's The Point

Kids will have fun measuring with a favorite character, but measuring with Mixie-Bot – or any non-standard unit – also helps kids understand the value of standardized units of measure such as inches and feet.

How Do I Do It?

  1. Download a Picture of Mixie-Bot (PDF).
  2. Print out the picture of Mixie-Bot and glue it to a piece of poster board or cardboard (you can even use an empty cereal box). Then cut her out. Tell your child that he’ll be using the Mixie-Bot cut-out to measure things around the house.
  3. Before he starts measuring, ask him to make some guesses about the items he’ll be measuring (e.g., “Which do you think is longer, the couch or the table?”, “Is your bed wider than the bathtub?”, “Which is taller, the lamp or the TV?”). Now let’s measure and find out!
  4. Measure one thing yourself to show your child how to measure with Mixie-Bot. Stand her up at one end, then move her end-to-end until you get to the other end of the object. Point out that each time you move Mixie-Bot you have to put your finger or some other kind of marker where Mixie-Bot’s head ends so you will know exactly where to place the bottom of Mixie-Bot as you move her along the object.
  5. As you move, count 1 Mixie-Bot, 2 Mixie-Bots, 3 Mixie-Bots, and so on.
  6. Take one of the items your child already measured and ask him to measure it again with something else that is shorter or longer than Mixie-Bot (e.g., a pencil or crayon). Ask your child, “Does it take more or fewer crayons to measure the item?”, “Why is that?” (If the crayon is smaller than the Mixie-Bot cut-out, it will take more crayons to measure the same object.)
  7. Take It Further

    Here’s a measuring activity you can do with the whole family. If you have a small family, invite some of your child’s friends to join in. Get a roll of string. Ask each person to lie down on the floor while your child measures a piece of string that is as long as the person is tall. Label each piece with the person’s name. Now tape each piece of string next to one another on a wall, starting at the same point for each string, e.g., the floor . Ask your child, “Which piece of string is longest?”, “Which is shortest?” Ask him to line them up from shortest to longest, and then from longest to tallest. Be sure that each string starts at the same point on the wall, and show the children how important it is to start at the same point for everyone.
