### Montessori Activity: Small Bead Frame - Dynamic Addition (With Exchange)

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:

1. Small bead frame
2. 1 worksheet
3. 1 green, red and blue pencil

1. Read a problem to your child, i.e.:

4679
