Children by Grade 2 are quite familiar with numbers and the way numbers work. It is in Grade 3 that kids get introduced to new concepts like fractions, lines and polygons. They also learn to read and understand time in 24-hour format. Concepts like fractions and lines and polygons form the basis of understanding higher grade concepts like operating with fractions, interpreting graphs. Understanding the concepts of area and perimeter, volume. At the end of Grade 3 children will be able to calculate mentally and understand concepts on paper with little help from physical objects.
