Mathematics

Kindergarten students will get an early start on mastering mathematical concepts by an increased focus on several critical areas:

• Algebraic Reasoning
• Number Sense and Operations
• Measurement
• Geometric Reasoning
• Mathematical Thinking and Reasoning

Below you will find some skills and processes your child will be expected to know and be able to do by the end of the school year.

The Kindergarten Student:

• counts to 100 by ones and tens and counts forward and backwards within 20 beginning from a given number.
• reads and writes numbers from 0-20 and represents a number of objects with a written numeral in this range.
• understands the relationship between numbers and quantities.
• uses ordinal numbers (first, second, third, fourth, and fifth) to describe the position of objects
• counts to answer questions about as many as 20 things arranged in various ways.
• identifies whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group.
• locates, orders, and compares two numbers between 1 and 20 as written numerals.
• adds and subtracts within 10 with procedural reliability.
• represents addition and subtraction in a variety of ways and solves word problems within 10 using objects, drawings, and equations with symbols for the unknown numbers.
• adds to make a 10 when given any number 1 to 9.
• represents numbers 0 to 10 as the sum of two numbers in different ways
• represent whole number 10 to 20 using a ten and a group of ones with objects, drawing, and expressions/equations.
• explains why addition and subtraction equations are true using objects of drawings
• understands the meaning of the equal sign
• describes measurable attributes of objects (e.g., length, weight, and volume) and directly compares two objects with a measurable attribute in common.
• expresses the length of an object as a whole number of length units, by laying non-standard objects end to end with no gaps or overlaps.
• collects, sorts, and counts objects into given categories and report the results.
• describes objects in the environment using names of shapes and describes the position of these objects (e.g., above, below, next to).
• names, identifies, compares, and analyzes two and three-dimensional shapes regardless of their size or orientation (squares, rectangles, circles, triangles, cubes, cones, cylinders, and spheres)
• creates and composes larger shapes from simple shapes or components.

In the Practice of Mathematics: 

In learning and understanding mathematics, students need to develop “habits of mind” so they can utilize math strategies, talk about the math they are learning and solve problems.  These mathematical standards will help your student learn content and apply mathematics to real world situations. 

The Kindergarten Grade Student:

• makes sense of the math and does not give up if the problem is unfamiliar or difficult.
• uses words and numbers to make sense of mathematical problems.
• explains how he/she solved a problem and actively listens and makes sense of others’ solutions
• shows his/her mathematical thinking using pictures, objects, drawings or symbols.
• chooses and uses mathematical tools to explore and understand mathematics.
• shares his/her ideas and thinking using accurate math vocabulary and computations.
• identifies a pattern or structure in the number system or shapes.
• notices when calculations are repeated then finds more general methods and short cuts.
