    A side-to-side plastic bead abacus. There are 10 wire rows of 10 beads each on a 9" x 8" plastic frame. The most helpful feature of the abacus is the use of blue and yellow colored beads -there are 5 of each color per row- which makes it more effective for all operations.

    A great tool for the visual and kinesthetic learner, the Place Value Abacus can take some of the confusion out of teaching/learning place value concept. This set includes 3 stands (each holds 3 pegs), 9 pegs, 81 beads, and 9 sets of 0 through 9 number tiles. There is a small ledge on the front of each stand on which to place the number tiles. Place one tile next to each peg and children can make the association between the digit and the number of beads placed on that peg. Use each stand separately to practice up to 3 digit numbers or connect the stands to practice larger numbers. There are no decimals included with the set, but you could make your own and place them appropriately on the ledge to practice decimal places less than one (tenths, hundredths, thousandths). ~ Donna

    This sturdy learning toy reminds me of the bead maze my kids had many years ago. The rainbow-colored plastic beads teach simple addition and subtraction as you slide them up and over a wood barrier. The barrier is made of 2 removable panels: one side shows colored ovals that match the beads, while the other side shows math problems (add/subtract 0-10). You can play with the beads and slide them over the colored metal arches too! They make a fun sound that kids like. Place the barriers back and practice your math! The overall shape is triangular as you start with one problem and one purple bead, then 2 problems and 2 lilac beads, until you have 10 problems and 10 red beads. 12.5” long x3.25” wide x6” high.

    Yes, you can buy an abacus as a math teaching tool, but with this kit you can build your own vertical abacus. The kit includes 90 colored cubes, 6 rods, 6 stands or bases for the rods, 12 number cards and a teacher guide. The bases slide together and there is a hole in each one for a rod to stand. The cubes are in a variety of bright colors and have a hole in the center for sliding onto the rods. The number cards have 6 holes at the back of each, so they can slide onto the rods, and then the front portion of each card has numbers or color patterns or number patterns or a simple addition problem to be solved by the student. A teacher guide is included with the set that offers suggestions for activities with your new vertical abacus – or "verticus." ~ Donna
