Racks and Tubes

Hi all,
I am making my own set of racks and tubes or test tube division
with pony beads (from Wal Mart) and these sets of printable  boards
from JMJ Publishing, game pawns, disposable plastic cups (cut down to
dish size containers for the beads) or any tiny bowl or container will work.
Craft bead tubes can be used to store each set of 10 beads.
The "boards" can be printed out, and then mounted on a heavier board
with holes punched in for the beads, with another board for backing glued
on to the board with the holes. All of this can be stored in a boxes or trays.

Have fun being creative!

Test Tube Division

Hi All,
 We've been busy working with a material in training that I have been
curious about how to use for some time...it is known as Test Tube
Division or Racks and Tubes. Here are some links to how to do the
lessons:

take a look here at the materials and Albanesi support materials)
Here is their blurb:
This material is used for both short and long division, with dividends up to the millions and divisors of 1 to 4 digits. The complete set of material consists of a) seven wooden racks (3 white for simple units, 3 grey for thousands, 1 black for millions) each containing ten glass tubes, each of which holds exactly ten beads; b) 700 hundred beads in green, blue or red, for the glass tubes; c) seven cups in white, grey or black on the outside and with the appropriate hierarchical color on the inside; d) four wooden division boards, hierarchically color-coded; e) four sets of wooden skittles in hierarchical colors, 36 in all, in a wooden box; f) a wooden tray for holding the material and a wooden box for storing the material.
