## Contents

### Age

3-6

### Materials

- Unlimited Golden Beads (no more than 9 thousand).
- Large Number Cards.
- At least 3 sets of Small Number cards.
- An Operational Mat.
- At least 3 trays and pots for carrying units.
- A floor mat.

### Preparation

### Presentation

- This is a group activity.
- Directress invites the children to take the Large and Small number cards from the shelf and to lay out the cards on the floor mat.
- Meanwhile, Directress sets up the 'bank' and lays out the operational mat on the table.
- The Directress sets an addition question, e.g. 1422 2145.
- She gives each of the two children a tray and specifies what numbers to bring for each of them.
- Each child has to go to the bank and collect the quantity of beads required, and then proceeds to collect the small number cards.
- They collect these on their tray and place them on the operational mat.
- The two amounts are arranged one under the other, with units below units, tens below tens and so on.
- Directress then invites one of the children to start counting the beads beginning with the units. as each column is counted (or added together), the beads are placed together right at the bottom of the mat.
- The total at the bottom is noted and the child is asked to get the corresponding Large number card, which will be superimposed and placed right at the bottom of the mat, i.e. a total of 3567.
- At the end of the operation, tell the children they have added together two smaller numbers and made one larger number.
