## Kindergarten

### What your child will learn

Students in Kindergarten continue to build their understanding of mathematics in real world situations.

• In Unit 1, students extend their understanding about directional and positional words. Students also sort and classify objects and explain the sorting rule. Students begin to ask questions to generate and organize data. Students are expected to identify, describe, copy, extend and construct simple patterns using a variety of concrete objects.
• In Unit 2, students will count and compare using numbers, words, and numerals. Students are expected to write and count with whole numbers to 31 or beyond. Students create and identify sets with more, less, or an equal number of objects, recognize sets as having an odd or even number of elements, use ordinal numbers first through fifth, and model single digit numbers in a variety of ways.
• In Unit 3, students strengthen their understanding of time as they learn to describe when events have happened or will happen. Students study measurement by describing and comparing measurable attributes of length and weight. Students begin to develop their understanding of the measurement process by using nonstandard units to measure length. Students investigate two-dimensional and three-dimensional shapes and describe the attributes of these figures.
• In Unit 4, students develop foundational understandings about estimation. Students also begin to develop an understanding that numbers are composed of parts. Students apply their understanding of the part-whole concept to joining and separating problems. In addition, students develop an understanding of money concepts and skills. Students explore and describe the attributes of a penny, a nickel, and a dime, as well as identify and state the value of these coins. Students count sets of pennies, sets of nickels and pennies, and sets of dimes and pennies through nineteen cents.
