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 is known as Test Tube
Division or Racks and Tubes. Here are some links to how to do the
lessons: (Gonzagareddi is much more expensive, but you can
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. The printed notes of this Montessori presentation from our CME Teacher Preparation Course are available for purchase from this webpage. Please search for: Long Division Game


  1. Where can you find the materials in the second picture? I love the drawer and box.

  2. Pruefl Montessori out of Austria and Germany has this set!

  3. Test tube racks are very important because test tube racks keep your test tubes safe.
