SPINDLE BOXES

Description

Materials
– Two boxes exactly the same, each with five compartments. At the back of each compartment is painted a symbol in black, starting from 0 and progressing serially up to 9.
– A container with 45 spindles

Presentation

1. 1. Introduce the child to the materials on the shelf and have him bring them over to the table.
   2. Point out the compartments and the numerals the child knows. Point to them all, one at a time, and have the child give the number’s names.
   3. Tell the child that these numbers will tell us how many spindles to put in the box.
   4. Point to the number 1. Have the child read it and then say, “We will put 1 spindle in this box.”
   5. Place one spindle in the compartment.
   6. Repeat for 2, counting the spindles as you place them, “One, two.” Continue this up to 4.

1. Have the child place the correct spindles in the remaining compartments.
2. Once all of the spindles have been placed, look at compartment 0 and notice that there is nothing in it.
3. Say, “This is zero. Zero means nothing. That is why there is nothing in this spot.
4. Have the child take out the two spindles from container 2. Have him do this one by one and count as he does so.
5. Repeat for the other spindles.
6. Then take out the 1 spindle and place it gently back into the basket.
7. Ask the child why there was no spindle in the 0 container.
8. Have the child replace the material on the shelf.

Purpose

Direct
The spindles clarify the idea that the symbols represent a certain quantity of separate objects.
To introduce the concept of zero and its symbol.
To reinforce the natural sequence of the numerals.

Indirect
To reinforce the idea that there are no other symbols other than 0
to 9.

Control of Error
If the counting has been incorrect, at the end there will be either
an insufficient number of spindles or some left over.
