Elementary arithmetic is a branch of mathematics involving addition, subtraction, multiplication, and division. Due to its low level of abstraction, broad range of application, and position as the foundation of all mathematics, elementary arithmetic is generally the first branch of mathematics taught in schools. [ 1][ 2]
Arithmetic is an elementary branch of mathematics that studies numerical operations like addition, subtraction, multiplication, and division. In a wider sense, it also includes exponentiation, extraction of roots, and taking logarithms . Arithmetic systems can be distinguished based on the type of numbers they operate on.
The 2006 Curriculum Focal Points identifies three critical areas at each grade level for pre-kindergarten through Grade 8. [15] Samples of the specific focal points for three grades are below. (Note that the Simple Examples below are not quotes from the Focal Points, but are based on the descriptions of activities found in the Focal Points.)
Cuisenaire rods are mathematics learning aids for pupils that provide an interactive, hands-on [ 1] way to explore mathematics and learn mathematical concepts, such as the four basic arithmetical operations, working with fractions and finding divisors. [ 2][ 3] In the early 1950s, Caleb Gattegno popularised this set of coloured number rods ...
The kindergarten grade is divided into two classes of roughly 15 students each. Kindergarten curriculum is focused on building foundational skills for learning the core subjects, such as developing reading and basic addition and subtraction skills. Kindergarten students also learn basic Spanish and how to tell time on an analog clock.
Subtraction is an operation that represents removal of objects from a collection. [ 1] For example, in the adjacent picture, there are 5 − 2 peaches—meaning 5 peaches with 2 taken away, resulting in a total of 3 peaches. Therefore, the difference of 5 and 2 is 3; that is, 5 − 2 = 3.
