# FAQ

What concepts can the Master eTools show?

On the how-to-use videos, we showed the features of the Master eTools website along with a few concepts for each of the MasterPieces (Blocks), MasterFractions (Fractions), and the Money Manipulatives.  However, there are many other concepts that the eTools and the manipulatives teach!

The MasterPieces (Blocks) show multiple concepts including counting, simple addition and subtraction, addition and subtraction with regrouping (aka carrying and borrowing), simple multiplication and division, multiple digit multiplication, division with or without remainders, and so much more.

The MasterFractions (Fractions) show multiple concepts including basic fractions, equivalent fractions, addition and subtraction of fractions with common denominators, addition and subtraction of fractions with uncommon denominators, multiplication and division of fractions, plus much more.

The Money manipulatives show dollars, quarters, nickels, and pennies.

You can visit PerceptionsMath.com for more information about our curriculum and the videos that show how to use the Master eTools (MasterPieces and MasterFractions) manipulatives.  Please note that no matter what curriculum you are using, the Perceptions Videos (which can be purchased separately) can show you how to make teaching math much easier by using the CRA methodology (Concrete – Representational – Abstract).

Where can I purchase the manipulatives shown on the Master eTools site?

You can purchase the MasterPieces (blocks), MasterFractions (fraction manipulatives), the Perceptions Math Curriculum, and the Perceptions Math Videos from PerceptionsMath.com
