### Montessori Activity: Small Bead Frame

Note: I am showing the large bead frame above, because it is not necessary to buy both the small bead frame and the large bead frame. I am using the large bead frame to do the small bead frame exercises.

AGE: 5.5 (after the child has worked with the Stamp Game)

OBJECTIVE(S):

To show the relationship between the different place values in the decimal system.

MATERIALS:

2. 1 worksheet
3. 1 green, red and blue pencil
4. 1 eraser
5. The Stamp Game (optional - for comparison with the Small Bead Frame)
6. The Golden Beads Introduction Tray (optional - for comparison with the Small Bead Frame)

PRESENTATION I (COMPARISON WITH GOLDEN BEADS):

1. Place the frame before the child and show him the four numbers printed along the left side of the frame.

2. Tell your child that the green beads on the 1st wire represent unit beads, say, "This is one unit." (At this point, you can bring out 1 golden unit bead and tell him that they are equivalent to each other).

3. Take out a quantity of unit golden beads, i.e. 5 and ask him to slide to the right the equivalent number of green unit beads, and he should slide out 5 green unit beads.

4. Tell your child that the blue beads on the 2nd wire represent the ten beads, say, "This is one ten." (At this point, you can bring out 1 golden ten-bar and tell him that they are equivalent to each other).

5. Take out a quantity of golden ten-bars, i.e. 3 and ask him to slide to the right the equivalent number of blue ten beads, and he should slide out 3 blue tend beads.

6. Tell your child that the red beads on the 3rd wire represent the hundred beads, say, "This is one hundred." (At this point, you can bring out 1 golden hundred-square and tell him that they are equivalent to each other).

7. Take out a quantity of golden hundred-squares i.e. 4 and ask him to slide to the right the equivalent number of red hundred beads, and he should slide out 4 red hundred beads.

8. Tell your child that the green beads on the 4th wire represent the thousand beads, say, "This is one thousand." (At this point, you can bring out 1 golden thousand-cube and tell him that they are equivalent to each other).

9. Take out a golden thousand-cube and ask him to slide to the right the equivalent number of red hundred beads, and he should slide out 1 green thousand bead.

10. If necessary, do a Three Period Lesson with the new beads on the Small Bead Frame.

PRESENTATION II (COMPARISON WITH THE STAMP GAME):

1. Place the frame before the child and show him the four numbers printed along the left side of the frame.

2. Tell your child that the green beads on the 1st wire represent unit beads, say, "This is one unit." (At this point, you can bring out 1 green unit stamp and tell him that they are equivalent to each other).

3. Take out a quantity of green unit stamp, i.e. 5 and ask him to slide to the right the equivalent number of green unit beads, and he should slide out 5 green unit beads.

4. Tell your child that the blue beads on the 2nd wire represent the ten beads, say, "This is one ten." (At this point, you can bring out 1 blue ten stamp and tell him that they are equivalent to each other).

5. Take out a quantity of blue ten stamps, i.e. 3 and ask him to slide to the right the equivalent number of blue ten beads, and he should slide out 3 blue tend beads.

6. Tell your child that the red beads on the 3rd wire represent the hundred beads, say, "This is one hundred." (At this point, you can bring out 1 red hundred stamp and tell him that they are equivalent to each other).

7. Take out a red hundred stamps i.e. 4 and ask him to slide to the right the equivalent number of red hundred beads, and he should slide out 4 red hundred beads.

8. Tell your child that the green beads on the 4th wire represent the thousand beads, say, "This is one thousand." (At this point, you can bring out 1 green thousand stamp and tell him that they are equivalent to each other).

9. Take out a quantity of green thousand stamps i.e. 6 and ask him to slide to the right the equivalent number of red hundred beads, and he should slide out 6 green thousand bead.

10. If necessary, do a Three Period Lesson with the new beads on the Small Bead Frame.

11. Show him how the color of the stamps matches the color of the beads of the small bead frame.

12. Show him how the numbers written on the stamps an the numbers written on the side of the bead frame.

PRESENTATION III (WITHOUT ZERO):

1. Write a number on paper, such as 3256.

2. Slide one green unit bead at a time to the right and count as you go along until you have moved 6 green unit beads to the right.

3. Do the same by sliding 5 blue ten beads, 2 red hundred beads and 3 green thousand beads to the right, counting them as you go away. Say, "You now have 3256."

4. Slide all the beads back to the left, invite your child to write a number on the notation paper and try out making this number on the bead frame himself.

5. Next invite your child to compose a number on the bead frame and composes the number on his notation paper.

PRESENTATION IV (WITH EXCHANGE - WITH ZERO):

1. Slide the green unit beads one by one to the right, and as you do so, say, "one unit, two units" all the way to 10 units.

2. After having counted 10 green units say, "Ten units make one ten," and move the 10 green unit beads back to the left and at the same time move 1 blue ten bead to the right.

3. Ask your child to record this on paper and ask your child if there is any green unit bead left. He will say no, and because there are no green unit beads left, ask him to write a zero in the unit column on the worksheet and a 1 on the ten column on the worksheet.

5. Repeat this for the tens, hundreds, and thousand.

6. Continue counting and moving 10 blue ten beads to the right.

7. After having counted 10 blue beads, say, "10 blue ten beads make 1 hundred," and move the 10 blue beads back while moving 1 red bead to the right.

8. Ask your child to record this on paper and ask your child if there is any blue ten bead left. He will say no. Ask him to write a zero in the ten column on the worksheet and a 1 on the hundred column on the worksheet.

9. Continue counting and moving 10 red hundred beads to the right.

10. After having counted 10 red beads, say, "10 red hundred beads make 1 thousand," and move the 10 red beads back while moving 1 green bead from the 4th wire to the right.

11. Ask your child to record this on paper and ask your child if there is any red hundred bead left. He will say no. Ask him to write a zero in the hundred column on the worksheet and a 1 on the hundred column on the worksheet.
