The decimal system is the name of the system of counting and measurement that is used commonly throughout the world. The decimal system is a system based on ten numerals.
They are the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
Because the MasterPieces have the abstract number imprinted on each block it makes understanding Number, Values, Shapes, and Space easy!
Addition or adding is the first level of arithmetic that comes after counting.
A whole number is simply the numbers 0, 1, 2, 3 (and higher). When we add two or more whole numbers together, it is the action of combining which creates another whole number with a greater value. When we combine we use the plus sign (+) to indicate the action of adding.
Using the MasterPieces, it is easy to see how the combining of two (or more) whole numbers works!
