Illustrative Math

The big ideas in IM Grade 2 include: extending understanding of the base-ten number system; building fluency with addition and subtraction; using standard units of measure; and describing and analyzing shapes. 

Unit 02: Adding and Subtracting within 100

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

Unit 03: Measuring Length

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

Unit 04: Addition and Subtraction on the Number Line

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.

Unit 05: Numbers to 1,000

In this unit, students extend their understanding of the base-ten system to include numbers to 1,000.

Unit 06: Geometry, Time, and Money

In this unit, students reason with shapes and their attributes, and partition shapes into equal pieces. This work helps to build a foundation for fractions. Students also solve story problems involving money, using their understanding of fourths, quarters, and skip-counting by 5 to tell time.

Unit 07: Add and Subtract within 1,000

In this unit, students use place-value understanding, the relationship between addition and subtraction, and the properties of operations to add and subtract within 1,000.

Unit 08: Equal Groups

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.

Unit 09

Students put together their understanding from throughout the year to cap off the major work and fluency goals of the grade.
