4.9 FOUR OPERATIONS WITH THE GOLDEN BEAD MATERIAL DIVISION (STATIC)

MATERIALS:

1. The same as for multiplication, subtraction and addition.

2. Prepared problem cards. Each symbol from the dividend should be a multiple of the divisor.

PREPARATION:

1. Lay materials out as described for other operations.

2. Invite 3 or 4 children.

PRESENTATION:

1. Choose a prepared card. Compose the dividend from the large symbol cards.

2. Take the divisor from the small cards, the division and the equals signs and arrange them in this manner: 8484 * 4 = _______.

3. Choose as many children as the divisor indicates (4), go to the bank and get the quantity (number of beads same as that of the dividend) and bring the material to the rug.

4. Give out the quantity to the 4 children who represent the divisor.

5. Start by putting the thousand cubes on their trays, then the hundreds, tens and units.

6. Do it slowly to emphasize that we must be very fair because division is dividing equally.

7. Divide the quantity until there is none left.

8. Check to see if each child has the same amount.

9. Tell the children that the answer is the amount each child gets.

10. Take the symbol cards for the quotient from the small numeral cards.

11. Read the equation.

12. Replace the material when finished with working.

CONTROL OF ERROR:

1. Each child has a fair share.

2. Verification of teacher.

AIMS:

1. Learning the operation of division.

2. Introducing the division sign.

AGE:

5 to 6 years.

DIVISION (DYNAMIC)

1. The process is the same except for division, the thousand category is exchanged with the hundred, the hundred category is exchanged with the tens, and the ten category is exchange with the units. This is the reverse process of addition, subtraction and multiplication.

2. The thousand category is counted out first and is taken to the bank for exchange first.
