In this unit, students identify, describe, compare, and create three-dimensional shapes (solid shapes). Students revisit counting, addition, and subtraction while working with familiar two-dimensional shapes (flat shapes).

In this unit, students count and represent collections of objects and images within 20. They apply previously developed counting concepts, such as one-to-one correspondence, keeping track of what has been counted, and conservation of numbers to larger numbers.

In this unit, students will reason about attributes (features) of shapes and learn about perimeter.

In this unit, students will work on reaching fluency goals for the concepts taught in grade 4 mathematics: Fractions, Whole-number Operations, Multiplicative and Division, Create and Design Mathematical Routines.

In this unit, students will deepen their understanding of the attributes and measurement of two-dimensional shapes.

In this unit, students will deepen and refine their understanding of geometric figures and measurement. Students will learn to draw and identify points, rays, segments, angles, and lines, including parallel and perpendicular lines. Students will learn how to use a protractor to measure angles and draw angles of given measurements, and to identify acute, obtuse, right, and straight angles in two-dimensional figures.

In this unit, students will make sense of multiplication as a way to compare quantities. Students will use this understanding to convert units of measurement and to solve problems about measurement.

In this unit, students will learn to express small and large numbers, from hundredths to hundred-thousands. Students will learn to write tenths and hundredths using decimal notation and to work with whole numbers within 1 million.

In this unit, students will deepen their understanding of how fractions can be composed and decomposed, and learn about operations on fractions.

In this unit, students will deepen their knowledge of fractions. Students will explore the size of fractions, write equivalent fractions, and compare and order fractions with the denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.

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.
