This activity is the child's introduction to the Golden Bead material. This material is a concrete representation of the decimal system.

## Presentation

1. Take the tray to a table or mat. Be sure that the thousand cube is on the left and the unit bead is on the right. 2. Take out the unit bead. Place it to the right of the mat. "This is one. We also call it a unit." 3. Take out the ten bar. Place it vertically to the left of the unit. "This is ten." 4. Take the unit bead and count over the units in the ten bar. "Let's see how many unit beads there are in a ten. One, two, three... There are ten units in a ten.” 5. Take out the hundred square, place it to the left of the ten bar, with the wires vertical. "This is a hundred." 6. Using the ten bar, count over the tens in the hundred square. "Let's see how many tens there are in a hundred. One ten, two tens, three tens... There are ten tens in a hundred." 7. Take out the thousand cube, place it to the left of the hundred square with the wires vertical to the mat. "This is a thousand." 8. Take the hundred square and count the hundreds in the thousand cube. Go from bottom to top. "Let's see how many hundreds there are in a thousand. One hundred, two hundreds, three hundreds... There are ten hundreds in a thousand." 9. Lay out all of the beads and name them one more time.
10. Do a three period lesson.
