Students in kindergarten will focus on understanding the meaning of whole numbers, including recognizing and writing numbers, counting a given number in a single set or combined sets and knowing how many there are without recounting. They will compare numbers or sets of objects and join and separate sets of objects to 10. Kindergarteners will build understanding of addition by adding to a number to make it larger. Students will also think of numbers as being made up of other numbers (part-part-whole). They will build understanding of subtraction by taking away a given amount from a set of objects and determine how many remain and compare two numbers. They will write simple number sentences to match situations. Kindergarteners will begin to understand that our place value system consists of tens and ones and that the placement of numerals determines the value of a number. They will identify, name, and describe two dimensional shapes such as squares, triangles, and circles and three dimensional figures such as cubes, cones, and spheres that are presented in a variety of ways. Students will experiment with measurement using nonstandard units of measure and measure objects by comparing them.
