Get Loopy! Make a 100th Day Necklace

First Grade Math Activities: Get Loopy! Make a 100th Day Necklace

What You Need:

  • Box of “Froot Loops” or other similar rainbow-colored “o” cereal
  • Length of clean string, about 24"
  • Scotch tape

What You Do:

  1. To prepare for this activity start by cutting a small length (about ½”) of scotch tape. Wrap it tightly around one end of the string to form a firm end, sort of like a shoelace tip. This helps little hands get strings through the holes in the cereal.
  2. Help your child tie a firm knot about 2" from the other end of the string.
  3. Pour out a large bowl of the cereal, and explain to him that he'll be making a necklace using exactly 100 of these o's. Here's the catch: in keeping with primary maths standards, you'll be doing this a special way, counting by tens.
  4. Have him start with ten o's of one colour, and string them on.
  5. He'll then move on to 10 pieces of a different colour, and so on up to 100, until he completes a full rainbow necklace.
  6. These necklaces usually look great and are lots of fun to make. But before you tie it off and place it on his neck, take a minute to savor some important learning. Stretch the string lengthwise on a table, and invite him to join you in counting off by tens!

Did you know?The Latin root word for “ten” is “deca”—which gives us all sorts of cool terms today. Lay your necklace, for example, on a table, and arrange it so that each colour makes one side of a geometric figure. Okay, it's a lot more complicated than normal year two geometric figures, but it sure is fun…you've made a “decagon”!
