Presentation
- Carry the material to a large mat. Place the box of bead bars in the upper right corner.
- For the first set of problems choose multiplication by 3, 4, 6, 7, 8, or 9. (We've used 7 here.) Take out one 7 bar and lay it horizontally as shown. Say, "This is seven one time. Seven times one."
- Use the pointer to count the beads.
- Lay the answer vertically beneath the first bead bar.
- Take out two 7 bars and lay them as shown. Say, "This is seven two times. Seven times two." Use the pointer to count until you reach ten. Leave the pointer in place.
- Take a ten bar from the box and lay it as shown. Continue counting the rest of the beads starting over from one to see how many beads are remaining.
- step seven
- step eight
- step nine
- Put all the beads back in the box. Repeat the process with another number.
- When doing multiplication of tens there won't be enough bead bars in the set to do all the problems. Do the first few and then reuse the bead bars for the next few. Allow the child to discover on her own the pattern in multiplication by ten.

Make Your Own
Not counting the cost of wire or a box, you would need to find beads for less than 2¢ a piece to be a better deal than the lowest cost pre-made option.
To make a set with 55 of each bead bar you will need a total of 3025 beads (55 red, 110 green, 165 peach, 220 yellow, 275 turquoise, 330 lavender, 385 white, 440 brown, 495 dark blue, and 550 gold). I've included the approximate price per bead for each: (¢).
