Grade 5 Math

CONTENTS

The exciting new year for every child, Grade 5 is one of the critical years of learning. This is also an important year from the perspective of concept absorption. From basic mathematics of addition, subtraction, multiplication, and division to more evolved concepts in decimals 5 elaborates on the applications of the basic concepts including the metric system, probability, fractions while introducing new facets of graphs.

Place values and number sense

In mathematics Number Sense refers to understanding of numbers, their relationship and how they are affected by the four basic operations. Number senses is important because it helps to develop useful strategies when counting, measuring or estimating.

Addition and subtraction

In the primary grades, students develop an understanding of part-whole concepts – they learn that two or more parts can be combined to create a whole (addition) or they can be separated from a whole (Subtraction).

Division

The sum or difference of terms which have variables raised to positive integer powers and which have coefficients. A polynomial can have constants, variables and exponents, but never division by variable. Even though the poly- means many the polynomials terms should be finite.

Symmetry and transformations

When two or more parts are identical after a flip, slide or turn we say it has symmetry. The simplest symmetry is reflection symmetry, sometimes called line symmetry or mirror symmetry. Other types of symmetries are Rotational symmetry and point symmetry. When we change a shape by using Turn, flip, slide or resize it is called transformation.
