Move your cursor on the Grade 2 tab above to reveal a drop-down menu of all 12 units and the dates you'll be teaching them this year. Click on the unit that you are looking for, and you'll be able to download standards and learning goals as well as see the essential questions and vocabulary that students will need to discuss the topics of that unit. (Please note that the blue, bolded essential question has been identified as the most crucial question for the unit, and will appear on the unit assessment.)


Here are the topics that students will be investigating this year:

Unit 1a Routines, Counting and Coins

Second grade students establish routines such as What Time Is It? and Number of the Day as well as explore coins. Students are also asked to consider if there are enough objects for their class, and if there would be any left over.

Unit 1b Addition and Subtraction

In this unit, students review making combinations of ten and solving story problems. Then, students explore what it means for a number to double and representations of doubling numbers.

Unit 2 Geometry

Building on to their previous units on shapes in kindergarten and first grade, students revisit the properties of shapes and sort them by their characteristics.

Unit 3a Number Strings and Story Problems

After their work with doubling numbers in the previous unit, students relate doubles to other number combinations as a strategy for adding. Additionally, work with story problems continues as students find ways to represent numbers that seem to be missing from the story.

Unit 3b Skip Counting and Place Value

By examining pairs and teams, students develop rules for odd and even numbers and then with stickers and strips of stickers begin to investigate the base-ten number system.

Unit 4 Data

Students practice sorting individuals into groups using rules and sorting and recording data, including how many pockets they have and how many teeth they have lost.

Unit 6a Using Place Value

In this unit, second graders add and subtract two-digit numbers while recording strategies for doing so. Multiples of ten are also examined in the game Roll-a-Square.

Unit 6b 3-Digit Numbers

Practicing skip counting, especially in the context of counting coins, is the focus of this unit. As they did in first grade, students count by twos, fives and tens.

Unit 7 Fractions

Students lay the foundation for fractions and division by discussing halves, thirds and quarters of objects. Coloring fractions of flags and determining whether or not sets of objects can be divided evenly among friends are some of the activities used to explore these ideas.

Unit 8a Efficient Strategies

In these investigations, students consider what happens when even and odd numbers are combined and when nine or ten are added to a single-digit number, as well as how these strategies can be used to make computations more efficiently.

Unit 8b Flexible Strategies

Students develop and practice strategies for addicting two-digit numbers, adding odd and even numbers, and adding nine and ten to one-digit numbers.

Unit 9 Measurement

As a continuation of kindergarten and first grade, students measure objects with various units and discuss whether or not they can be compared. Measuring with standard units, inches and feet, is introduced.
