### Montessori Activity: Static Addition Without Golden Beads - Vertical Presentation

Age: From 5 years old

Materials:
1. Worksheets
2. Pencil and eraser

Directions:

2. Show your child how to read the question by reading it to your child. E.g.

5
+ 3
-----
?
-----

(You could also show him the horizontal presentation first, and then write it in vertical presentation, for him to see the relation)

3. If your child could not derive the answer mentally without golden beads, teach him to draw "o's" to represent the quantity in place of the golden beads.

4. Ask your child to count the "o's" and show your child to write the answer on the unit place value space.

6. Let your child try with the next single digit question.

7. Move on to double digit addition questions.

8. Show your child how to read the question from left to right E.g.

25
+ 24
-----
?? <---
-----

9. Put an arrow to the left of the space where the unit place value shall be and explain that when answering addition problems, start from the unit place value.

10. Starting from the unit place value, ask the child, what is 5+4=? Your child should say 9. If he has difficulties, encourage him to draw "o's" to represent each quantity next to the number.

11. Ask your child to write the answer "9" onto the unit place value answer space:

25
+ 24
-----
?9 <---
-----

12. Move to the ten place value, and ask your child what is 2+2=? Your child should say 4. If not, encourage your child to draw appropriate number of "o's" next to the respective number.

13. Explain that the answer "4" is at the ten value place, and thus it represent "40".

14. Ask your child to write the answer "4" onto the ten place value answer space.

25
+ 24
-----
49 <---

16. Let your child try with the next double digit question.
