## Grade 2 Components

Learn about the various components that make up the Core Curriculum Package in Grade 2, including: materials available in Spanish; materials included in the Manipulatives Kit, the Completer Kit, and the Cards Package at Grade 2; and additional, optional resources.

## Classroom Cases

Teacher-written Classroom Cases about supporting the range of learners in 2nd grade are available for download here and here. The latter deals specifically with problems about 10s and 1s.

## Pacing

This document lists the Grade 2 units, the number of sessions in each one, and the total number of sessions in the Grade 2 curriculum. It also contains information about the expectations for the number of minutes spent per day on mathematics.

*Investigations* and the CCSS

Learn more about *Investigations* and the Common Core State Standards at second grade. The sample Session, How Many Hundreds?, is one of several Sessions that focus on the place value of three-digit numbers and on adding or subtracting 10 or 100 to/from a given number. It is designed to be incorporated at the end of the sixth Grade 2 unit, *How Many Tens? How Many Ones?: Addition, Subtraction, and the Number System 3*. The instructional plans layout Session-by-Session changes to each Investigation in that unit.

## Classroom Video

What does an *Investigations* classroom look and sound like? The videos below provide images of teachers and students at work in a range of second grade classrooms.

The class collects data about the number of pockets each student is wearing. Then they figure out how many pockets the class is wearing altogether.

A student describes her strategy for solving 22 + 10. The teacher talks with her about what she recorded.

One student uses a number line to show how he solved 39 + 22, using the strategy of keeping one number whole and adding the other number on in parts.

One student shares his strategy for solving 69 + 87.
