PrerequisitesNumber Rods

Materialsspindle boxes
45 identical spindles
container for spindles

This activity lets the child practice associating the numerals and quantities 0-9.

## Presentation

1. Carry the material to a mat or large table.
2. Point to the zero. "Zero means nothing. We don't put anything in here."
3. Point to the 1. "How many does it say to put in here?"
4. Put one spindle in the space.
5. Point to the 2. "How many does it say to put in here?"
6. Put two spindles in the space.
7. Continue like this until all of the spaces have the appropriate number of spindles.
8. "Let's see how many are left in the box...Zero!"

## Points of Interest

1. The concept of the number zero representing none.

## Control of Error

• There are exactly enough spindles to complete the work. If at the end there are not enough, or if there are extra left over the child will know that there is a mistake.

## Variations and Extensions

Variation 1: Count each spindle as they are replaced in the box and point out the numeral again.

Variation 2: Ask the students to count the total quantity of spindles as they are replaced in the box (45).

## Aims

Direct Aim:

1. To show the collection of quatities into the single set.
2. To show the sequence of nine
3. To show zero as an empty set
4. To show nine as the first group in our decimal system, not ten.

Indirect Aim:

1. Use of nines
2. Ten is a new level

## Material

The material consists of two wooden boxes with five long compartments in each. The back of each compartment has a numeral printed on it. Zero to four are in the first box and five to nine are in the second box. The container has forty-five wooden spindles total.

• This version was made by gluing segments of cardboard tube onto two narrow boards. The numerals were written on cards with a marker and glued to the front. The spindles were made from sticks cut to the same length.

• This version was made from two cardboard boxes with balsa wood dividers hot-glued in place. The spindles are popsicle sticks.
