Kindergarten Mathematics Standards

kinder-successA kindergartner will learn to count, to read and write numbers up to 20 and simple addition and subtraction. Here are a few examples of what your child will learn and practice throughout the year, questions to ask his or her teachers and tips for reinforcing academic skills at home.

Counting and Cardinality

  1. Count by ones and tens to 100.
    Ones: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, …, 97, 98, 99, 100
    Tens: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
  2. Compare numbers between 1 and 10; be able to choose the bigger number.
    Q: Which number is bigger, 5 or 9?
    A: 9 is bigger
  3. Count objects in a group up to 20; compare two groups and tell whether they are equal or if one group is greater than or less than the other.
    Q: You have a group of 10 objects and another group of 15 objects. Which one is bigger?
    A: The group of 15 objects is bigger.

Operations and Algebraic Thinking

  1. Understand addition and subtraction as “adding to” and “taking away,” respectively.
    5 take away 3 = 5 – 3 = 2
  2. Depict adding and subtracting using objects, shapes, fingers, drawings and sounds (such as snapping or clapping).
  3. Using the numbers 1 through 9, find two numbers that add up to 10.
    9 + 1 = 10
    8 + 2 = 10
    7 + 3 = 10
    6 + 4 = 10
    5 + 5 = 10
  4. Add and subtract within 5 quickly and easily.

Number and Operations in Base Ten

  1. Recognize numbers 11-19 as ten plus additional ones.
    10 + 1 = 11
    10 + 2 = 12

    10 + 9 = 19

Measurement and Data

  1. Understand the different ways objects can be measured such as length, height and weight (how long, how tall, how heavy).

Geometry

  1. Name shapes and use simple language to describe them.
    Triangles have three sides and circles are round.
