In this unit, students will learn about factors and multiples and apply their understanding of the area of rectangles. Students will determine if a number between 1 and 100 is prime or composite.

In this unit, students will work on reaching fluency goals for the concepts taught in Kindergarten mathematics: counting and comparing, math in our environment, fluency within five, 10 as a benchmark for 20.

In this unit, students will learn about the concept of area and relate area to multiplication and addition.

In this unit, students will learn about and use the relationship between multiplication and division, place value understanding, and the properties of operations to multiply and divide whole numbers within 100. Students will also represent and solve two-step word problems using the four operations.

In this unit, students will develop an understanding of fractions as numbers. Students will represent fractions with diagrams and number lines and compare and find equivalent fractions.

In this unit, students will generate and represent length measurement data in halves and fourths of an inch on line plots. Students will learn about and estimate relative units of measure including weight, liquid volume, and time, and use the four operations to solve problems involving measurement.

In this unit, students will work on reaching fluency goals for the concepts taught in grade 3 mathematics: Fractions, Measurement and Data, Multiplication and Division, Create and Design Mathematical Routines.

In this unit, students develop their understanding of addition and subtraction as they represent and solve story problems.

In this unit, students recognize numbers and quantities in their world.

In this unit, students add and subtract within 10 and answer questions about data.

In this unit, students will work on reaching fluency goals for the concepts taught in grade 2 mathematics: Fluency within 20 and Measurement, Numbers to 1,000 and Creating and Solving Story Problems.

In this unit, students develop an understanding of equal groups as the foundation for multiplication and division in Grade 3 and beyond. This understanding builds on students' experiences with skip counting and finding the sums of equal addends.

In this unit, students will use place value understanding, the relationship between addition and subtraction, and properties of operations to add and subtract within 1,000. Students will also add and subtract within 1,000 with and without composing and decomposing a base-ten unit.

In this unit, students will work with shapes by sorting them and noticing their sides and angles. Students will divide shapes into equal parts and build a foundation for working with fractions. By the end of the unit, students will be able to use words like halves, thirds and fourths, skip-count by 5 to tell time, and solve story problems involving the values of coins and dollars.

In this unit, students will extend their place value understanding to three-digit numbers.

In this unit, students learn about the structure of a number line and use it to represent numbers within 100. They also relate addition and subtraction to length and represent the operations on the number line diagram.

In this unit, students measure and estimate lengths in standard units, and solve measurement story problems within 100.

In this unit, students add and subtract within 100 using strategies based on place value, properties of operations, and the relationship between addition and subtraction. They then use what they know to solve story problems.

In this unit, Students represent and solve story problems within 20 through the context of picture and bar graphs that represent categorical data. Students build toward fluency with addition and subtraction.

In this unit, students will work on reaching fluency goals for the concepts taught in grade 1 mathematics: addition fluency within 10, relate addition and subtraction, add and subtract within 20, change unknown story problems, put together and take apart story problems, compare story problems, count large collections, solve and write number riddles.

In this unit, students focus on geometry and time. They expand their knowledge of two- and three-dimensional shapes, partition shapes into halves and fourths, and tell time to the hour and half of an hour.

In this unit, students extend their knowledge of linear measurement while continuing to develop their understanding of operations, algebraic thinking, and place value.

In this unit, students add within 100, using place value and properties of operations in their reasoning.

In this unit, students develop an understanding of place value for numbers up to 99. This unit is the first introduction to the base-ten system.

In this unit, students solve new types of story problems within 10. They develop an understanding of the meaning of the equal sign and connect story problems to equations.
