1. Arrange the layout as shown in the above picture above.
2. Explain that the green chips represent units, blue chips representing tens, red chips representing hundreds and white chips representing thousands.
3. Invite your child to read the first equation or you can also read it together, for e.g. 2535+1566=? |
AGE: 5.5 years old (after your child has tried The Bank Game and Vertical Static Addition)
OBJECTIVE: To introduce the child to dynamic quadruple digit addition
MATERIALS:
1.
19 green chips representing units
2.
19 blue chips representing tens
3.
19 red chips representing hundreds
4.
9 yellow chips representing thousands
5. 1 quadruple digit addition worksheet
6. 5 felt pieces
7. 1 pencil and eraser
PRESENTATION:
1. Arrange materials as shown above.
2. Explain that the green chips represent units, blue chips represent tens, red chips represent hundreds and white chips represent thousands.
3. Read the first equation i.e.
2535+
1566=?
4. Point to the unit place value of the first addend in the worksheet and ask, "How many units are there?" Your child should answer
5.
5. Take
5 green chips and place it on the felt piece to the right of the worksheet in a vertical line.
6. Point to the ten place value and ask, "How many tens are there?" Your child should answer
3 tens.
7. Take
3 blue chips and place it vertically to the left of the selected green chips.
8. Point to the hundred place value and ask, "How many hundreds are there?" Your child should answer
5 hundreds.
9. Take
5 red chips and place it vertically to the left of the selected blue chips.
10. Point to the thousand place value and ask, "How many thousands are there?" Your child should answer
2 thousands.
11. Take
2 yellow chips and place it vertically to the left of the selected red chips.
12. Point to the second addend and repeat the process. (Your child should count out the unit red chips, ten blue chips, hundred red chips and thousands white chips from the second addend, i.e.
6 green chips,
6 blue chips,
5 red chips and
1 yellow chip and place them on the right felt piece below the first addend's collected chips.)
13. Add the chips together by pushing the second addend's chips up together with the first addend's chips.
14. Invite your child to count the
green chips. When he reaches the
10th unit, ask him/her to exchange for
1 blue chip, saying "
10 units (green) is the same as
1 ten (blue)," and place the it above the other blue chips.
15. Ask your child to count the remainder green chips, i.e.
1 green chip in this case, and write the number in the unit place on the worksheet.
16. Invite your child to count the blue chips. When he reaches the
10th chip, ask your child to exchange for 1 red chip, saying "
10 tens (blue) is the same as
1 hundred (red)." and place the it above the other red chips.
17. Ask your child to count the remainder blue chips, i.e.
0 blue chip in this case, and write the number in the ten place on the worksheet.
18. Ask your child to count the red chips. When he reaches the
10th chip, ask your child to exchange for 1 yellow chip, saying "
10 hundreds (red) is the same as
1 thousand (yellow)," and place the it with the other white chips.
19. Ask your child to count the remainder red chips, i.e.
1 red chip in this case, and write the number in the hundred place on the worksheet.
20. Ask your child to count the yellow chips, i.e.
4 yellow chips in this case, and write the number on the thousand place on the worksheet.
21. Ask your child to say the question, count and write the answer (if this is not written down along the way earlier), for e.g.
2535+
1566=
4101
22. Invite your child to try the next equation.
