The ability to count from one to one hundred is an important achievement for your kindergartner, as it is the foundation for the base ten system of numbers. In addition to comparing numbers to determine which are larger or smaller, your kindergartner should be able to both count and separate numbers into in units of one and ten. For example, given the number 15, your kindergartner should be able to describe this number as having one unit of ten and five units of one. Your kindergartner should also develop the ability to write numbers one through twenty.
Your kindergartner should also absorb the elemental principles of addition and subtraction as they progress towards making sense of number problems and how to solve them. Students should be able to demonstrate addition and subtraction in a variety of ways, including demonstrations using their fingers or manipulatives, vocal descriptions or written expressions.
Kindergartners learn to collect measurements, such as lengths, weights or numbers of objects, and then use this data to draw comparisons. For example, given two cups holding different numbers of jelly beans, kindergartners should be able to determine that one of the two cups has fewer beans than the other, by counting, weight or observation. Your kindergartner should also begin to understand time, such as the difference between morning and afternoon as well as its measurement on a clock and the days in a week.
Comprehending the basic components of shapes is an essential skill for your kindergartner. Students should be able to recognize simple shapes, such as squares, circles and triangles. They should be able to determine whether a shape is in front of, below or above another shape. Kindergartners should also identify those shapes from two-dimensional or three-dimensional perspectives.
