Ideas for Manipulatives

Created and Written by Jacquie Fisher

 
Teaching kids to count to 100 is a big milestone and one that parents and teachers work on for a few years. 
It's a long journey fraught with numbers like "fifteen-ten" and other assorted creative ways to count. 
And along the way, kids are also learning to count by 2's, 5's, 10's and categorize numeric values.
For a number of years, I remember my kids coming home with a note asking that each child in the class bring in "100 of their favorite item" to celebrate the 100th day of school.
100 of their favorite item -- whew!  Now those were some long discussions --
Kid:  "How about 100 stuffed animals Mom?"
Me:  How about we think of something a little smaller?
Kid:  "I want to bring in something that the other kids won't bring."
Me:  Ok, how about crayons?
Kid:  No
Me:  Tattoos?
Kid:  No
And so it went for about 50 more suggestions until we finally came up with a winner! 
And in the process, we also came up with quite a list of possibilities in case you're having trouble thinking of small items for your 100th Day of School.

100 Items to Use to Count to 100

There are some super fun ways to help kids practice all this counting.  One popular idea is to introduce a 100's Jar.  Similar to an estimation jar in many classrooms, a 100's Jar holds one-hundred pieces of the same item. 
If you use plastic bottles or jars, you can introduce a number of math concepts such as volume, size and weight.  So the first part of our list includes lots of items that can be counted, sorted, categorized and compared.
I had some extra canning jars that we used to do some counting and comparison.  Just make sure that the jar or bottle you use it transparent so the kids can see & explore the items inside it.  I've also tried to make life easier for you by including affiliate links to items that may not be well-known or might be hard to find.

Items to Count

Since items in this group are so similar, they are great to use for counting by 2's, 5's and 10's when they are sorted.
1.  Paperclips
2.  Pencils
3.  Ping pong balls
4.  Cap Erasers (great to revive old pencils)
5.  Pennies (use with other coins to learn how to count money)
6.  Nickels
7.  Dimes
8.  Quarters
9.  Plastic spoons
10.  Binder Clips (good for finger dexterity)
11.  Puzzle pieces (then put together the puzzle)
12.  Game tokens
13.  Rubber bands

100 Items to Use in your Estimation or Counting Jar

30.  Bookmarks
31.  Old keys
32.  Golf tees

Sort by Type

33.  Backpack clip toys or animals
34.  Happy Meal toys
35.  Tattoos
36.  Small Maze Puzzles (by shape or color)

Some of our nature items would also fit in this category such as rocks, seashells, pinecones and flowers.  They are all listed below under natural materials.

Comparing 100 popped and unpopped kernels of corn
Such a fun idea - compare popcorn both unpopped & popped!

Items that Teach Volume/Area

I love this type of item -- things that change the space they take up depending on how they are presented to the kids.  These are pefect for a math/science discussion!
45.  Paper or Plastic Cups (stacked one inside the other and stacked as a pyramid)
46.  100 millileters of a liquid (look at it in a cup and then pour it out on a cookie sheet or pie plate to discuss area)
47.  Balloons (both blown up and flat)
48.  Popcorn kernels (unpopped and popped)

If you use mini-marshmallows and toothpicks for your 100's jar, you can then pair them to create constellations for science exploration!

Super items to use for counting and then experimenting!
63.  Mentos (count and then use them to make volcanoes)
64.  Toothpicks (combine with mini-marshmallows to make constellations)
