Rainbow Bead Abacus provides hand-on learning for counting and addition, subtraction, multiplication and division. It's all wood and stands upright. It has ten rows of color wooden beads, each row has ten beads and the beads can slide from one side to the other. With all the color beads to slide back and forth on the different rods, it can be used as a toy for toddler as well.

To learn to count from 1 to 10, .... or 1 to 100, slide one bead at a time from one side to the other side and saying out the number of beads that have been moved. This help to imprint the concept of a number visually with the amount of the beads moved.

To learn addition, slide the number of beads corresponding to one of the numbers to be added to one side. Then on the second row, slide another set of beads corresponding to the other number to be added to the other side. Then count the total amount of beads at the other side of the two rods to give the sum of addition.

To learn subtraction, slide the number of beads corresponding to number to be subtracted from to one side (called Side "A"). Then on the same rod, slide back the number of beads corresponding to the number to be subtracted back. Then count the total amount of beads at Side "A" to give the answer.

To learn multiplication, slide the number of beads to be multiplied to the other side (called Side "A"). Repeat this on the next row and next row and so on as many times as the number to be "multipled by". Then count the total of beads at Side "A" of all the rods to give the product or answer of the multiplication.

To learn division, slide the number of beads corresponding to the number to be "divided by" to the other side (called Side "A"). Repeat this on the next row and next row and so on until the total number of beads at Side "A" from all the rods reach the number to be divided. (To find out whether the total number of beads at Side "A" from all the rods, just count all the beads at Side "A" for all the rods.) Then count the number of rods that has beads on Side "A" to give the answer.

For ages 2 to 10.
