3D model description

  • This is a tiny abacus, a modern version of an ancient tool used to help people keep track when counting.

  • Very useful when teaching kids math between the ages of 4-7. (kindergarten & 1st grade in the US.)

-My kid was doing addition/subtraction on her fingers & on the number row on paper but was limited to basically +/- 10. With this tool she can literally figure out that 567 - 123 = 444, because you only have to shift a few beads around to do it!

-It also happens to make a great fidgeting toy since its just fun to flip around in your hand!

HOW DO YOU USE IT?
-There are 3 rows of beads, each row has 10 beads.

-The side of the abacus is labeled for up to a 3 digit number. The hundreds place the tens place, and the ones place.

-Start at the ones place & count each bead sliding it from left to right: 1,2,3,4... When you get to 10 then trade the entire top row for a single bead on the second row (10's place). Repeat!

DIMENSIONS: -2.5" x 2" x 0.5"
