Spindle Boxes
Spindle boxes are ten compartments marked 0 to 9 and 45 wooden spindles, for counting work from about 4. Sets cost $45.00 to $138.90 at the three US sellers we checked on October 2, 2026. An egg carton marked 0 to 9 and 45 craft sticks make a homemade set that works just as well.
The first lesson with it is Spindle Boxes: Counting 0 to 9. Not sure your child is ready for it? Two minutes of questions place your child on the sequence.

What the spindle boxes are for
The numeral comes first here and the child makes the quantity: read 7, count seven spindles in. The 0 compartment stays empty, which is how zero gets taught. With exactly 45 spindles, the box checks itself, since 0 + 1 and so on up to 9 is 45.
Montessori's 1912 version was two trays of five compartments with large wooden pegs. The long box and thin spindles are the later form of the same material.

- Alison's $45.00 and Montessori Outlet's $48.95 sets are one long box; Alison's $113.00 premium set is two boxes of five, like Montessori's own trays. Either layout teaches the same lesson.
- Count the spindles when the set arrives. The lesson depends on exactly 45.
- This is a good material to make instead. The egg carton build below costs almost nothing and checks itself the same way.
- Kid Advance returned an error for us, Montessori Services had no spindle box, and Amazon's search page wouldn't load.
Making the spindle boxes at home
What to gather
- A cardboard egg carton for a dozen, or ten small bowls
- 45 craft sticks or new unsharpened pencils
- A marker
- A basket or jar for the sticks
- Nine ribbons or hair ties, optional
| Piece | Size and marking | How many |
|---|---|---|
| Egg carton | Cut down to two rows of five cups | 1 |
| Sticks | Craft sticks or pencils of one length | 45 |
- 1Cut two cups off a dozen-egg carton, leaving two rows of five.
- 2Write 0 to 4 along the top row and 5 to 9 along the bottom, in big numerals.
- 3Count out exactly 45 sticks into the basket, and count again.
- 4Lay the carton with 0 at the top left, so the numbers read like a page.
Keeping a full set on the shelf
- Count the 45 spindles back into the basket after every turn. One missing spindle turns a right answer into a wrong one.
- Check the spindle ends now and then, and sand any that split.
Questions parents ask about the spindle boxes
One spindle box or two?
Either. Montessori's 1912 trays were two sets of five compartments; most budget sets are one long box of ten. The lesson is the same.
Can I use something other than spindles?
Yes. Montessori used large wooden pegs and said to vary the objects. Craft sticks or pencils work, as long as there are exactly 45 and they don't roll.
Why 45 spindles?
Because 0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45. With exactly 45, a filled box leaves nothing over and nothing short.
Before the spindle boxes, make sure the work before it is solid. The sandpaper numerals lesson lists the signs that a child is ready to move on.
