3. Place the first addend on the top, leaving room for the second addend.
4. Lay out the second addend, lining up the categories carefully.
5. Push the second addend up so that the stamps will touch each other, emphasizing, "We are putting these amounts together."
6. After putting the addends together, count the stamps starting with units.

8. If not, he may bring the symbols to match the whole quantity and compose the number and read it.
2. Repeat the same steps as for static addition except for counting the answers.
3. Count the units. If you reach 10, tell the child that you must exchange for a ten stamp.
4. Put 10 unit stamps back in the box and place the exchange stamp on top of the row of tens.
5. Count the 10 stamps. When you reach 10, tell the child, "When need to exchange for a 100 stamp."
6. Leave 10 tens in the box and take a 100 stamp.
