TOS Review - Master Innovations Master Ruler

We recently had the opportunity to review Master Innovations, Master Ruler.  Master Ruler is one of those products where a teacher saw a need and went about creating a solution.  Seeing her students frustrations and confusion when trying to understand the fractional components of measurement, she invented a special ruler that enables any student to be able to clearly see the various fractions, from 1/2 to 1/16 by using a cleverly designed ruler that has overlays for each fraction.  The products logo (pictured above) gives a clear picture of the color coded fractions and their representative lines on the ruler. The color coding and the length of the lines make it very easy to see where each fraction lies and how they correlate to each other. Super easy to see that 1/2 is the same as 2/4, 4/8 and 8/16!

Included in our package we received a Master Ruler with U.S. measurements as well as a Master Ruler with metric measurements (same design only using centimeters, millimeters, etc.), a student workbook (that is reproducible) and a really nice poster to display on the "Marvels of Measures"

I used this ruler with my 11 year old dd who has some struggles with math.  We worked through the student workbook with her measuring and converting.  At first she was befuddled, because it was all new to her but as we worked through the problems and converted from one fraction to another, she began to see the connections and began to work through the conversions on her own with very little trouble.  I love when math becomes fun for my math challenged daughter. :)

Here is the breakdown of the costs for the various products:

Master Ruler (U.S.  or Metric) $9.95 each
Student Workbook  for $15.95
or you can purchase The Master Ruler Starter Set which includes metric, U.S. and a teachers ruler as well as the workbook  for $41.25  (we did not receive the Teachers Ruler as part of our review).

To see videos on how the Master Ruler works, click on the above links of each product. Master Innovations has created many You Tube video's showing how to use their products.


Master Innovations has created other products using the same concept as the Master Ruler for clocks, fractions and angles. Check out their unique approach to helping students actually see these concepts.
