Addition and Subtraction
Using your finger, use the beads to show the correct number of beads as an answer. Example: Start with one bead on the right. Push 2 more beads to the right. Now there are three beads on the right. We can also write this as “1 + 2 = 3”. 1 2 3 4 5 6

Product Description
An abacus is a very old way of adding and subtracting, from before people had calculators. It is a set of beads arranged on a counting frame. ■ Your abacus has 100 separate beads in 5 different colors, spread across 10 rows. Number references are marked on the frame both horizontally and vertically. ■ An abacus is excellent at developing children’s counting and addition/subtraction skills. Practice counting up or down, and demonstrate an understanding of the relationship between numbers and quantities. ■ This abacus has a built-in stand on the frame that can be folded away for easy storage, or transportation. To stand it up again just fold the legs out. ■
Tips and Tricks Abacus Stand
Lift the leg brackets gently at the joints to release the pins. Slide the pins all the way down until they reach the notches that hold them. This will lock the legs into the standing position. The abacus will be able to stand up by itself.
Numbers and Quantities
Start with all the beads on the left-hand side of the frame. Read the questions below and answer them by moving the required number of beads across to the right-hand side. Use the beads to find the correct answers to the questions. Example: 1. How many white beads are on the right side of the abacus?
Slide the legs down.

Which Row has More?
Packing the Abacus Away Lift the pins out of their notches and slide them toward the top of the abacus. The legs should easily fold flat against the side of the device.
Lift the pins and slide them up, toward the top of the abacus.
Counting Up and Down
Look at the picture and see how many beads are on the left side of the abacus. Without counting, see if you can work out how many beads are on the right-hand side. Do you notice a pattern? What is the difference between the two sides?
Start with all the beads on the left side of the frame. Now set up the beads according to the picture. Use your abacus to find out which row has the most, or the fewest beads. 1. Which row has more beads? (Row 1: four white beads. Row 2: one green bead.)
2. Which row has more beads? (Row 1: three white beads. Row 2: five green beads.)
