Montessori Activity: Stamp Game - Dynamic Addition

AGE: 5.5 years (after the child is familiar with the decimal system, Static Addition With Golden Beads and Dynamic Addition With Golden Beads)

OBJECTIVE(S):

To teach addition without using golden deads.

MATERIALS:

1. Stamp Game
2. Addition worksheet
3. Pencil and eraser
4. 1 mat (optional)

PRESENTATION:

1. Read the first equation i.e.

2535
+1566
--------
?
--------

2. Arrange the stamps showing the first addend e.g. 2535

3. Use a ruler to make a divider under the first addend.

4. Arrange the stamps showing the second addend e.g. 1566

5. Remove the ruler divider.

6.  Move the second addend up to join the first addend.

7. Count the unit stamps and stop when you have counted 10.

8. Put the 10 unit stamps into the units compartment and take out 1 ten stamp. Place the ten stamp after the other stamps in the tens column.

9. Count the remaining units and write down the answer on the paper.

10.  Count the ten stamps and stop when you have counted 10.

11. Put the 10 ten stamps into the tens compartment and take out 1 hundred stamp. Place the hundred stamp after the other stamps in the hundreds column.

12. Count the remaining tens and write down the answer on the paper.

13.  Count the hundred stamps and stop when you have counted 10.

14. Put the 10 hundred stamps into the hundreds compartment and take out 1 thousand stamp. Place the thousand stamp after the other stamps in the thousand column.

15. Count the remaining hundreds and write down the answer on the paper.

16. Count the thousands and write down the answer on the paper.

17. Ask your child to say the question, count and write the answer on the paper (if this is not written down along the way earlier), for e.g.

2535
+1566
--------
4101
--------

17. Invite your child to try the next question.

ADDITIONAL INFORMATION:

Our Little FECS (5Y10M18D) tried this for the first time today 23 Jan 2015. Since he is very familiar with place value through the other Montessori exercises prior to this, we went straight to the thousand place value. He is getting a grasp of the concept, but needs guidance and reminders through the steps. For example, he would put back the 10 units, but take a hundred stamp, during the exchange. We need to repeat more exercises with exchanges and I need to learn to be patient and be more encouraging. Like most children, he prefers the stamp game to the golden beads, as he finds it easier to take the stamps than to take the golden beads. But I would not discount the golden beads and jump straight to stamp fame, as the golden bead materials sets a very good foundation step for children. Our Little FECS are also intrigued by the skittles in the stamp game - he thought it is for playing chess (he is currently crazy about playing chess at the moment), but I told him that it is for division, and we haven't reach there yet.
