Math Content describes the mathematical work of Grade 4 in each of the following content areas: Multiplication and Division and Addition, Subtraction, and the Number System (both listed under Number and Operations -Whole Numbers); Rational Numbers; Patterns, Functions, and Change; Data Analysis and Probability; and Geometry and Measurement. The mathematical emphases and benchmarks in each content area are also included.

Scope and Sequence contains the mathematical emphases, math focus points, and assessed benchmarks for each of the units in the Grade 4 sequence.

Sample Sessions

Explore a Session from the first Grade 4 unit, Factors, Multiples, and Arrays: Multiplication and Division 1. All of the materials referenced in the Session—Resource Masters, Student Activity Book pages, Student Math Handbook pages, and a Dialogue Box—are also included.

Grade 4 Components

Learn about the various components that make up the Core Curriculum Package in Grade 4, including: materials available in Spanish; materials included in the Manipulatives Kit, the Completer Kit, and the Cards Package at Grade 4; and additional, optional resources.

This document lists the Grade 4 units, the number of sessions in each one, and the total number of sessions in the Grade 4 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 fourth grade. The sample Session, Multiplicative Comparison, introduces multiplication situations where one factor is a certain number of times larger, or smaller, than the other factor. It is designed to be incorporated in the first Grade 4 unit, Factors, Multiples, and Arrays: Multiplication and Division 1. 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 fourth grade classrooms.

Students count around the class by 6. They pause partway through to think about how many students have counted, and how they know.

A student shares her strategy for solving 424-289.

Students compare two strategies for solving 145 + 226, one of which is the US standard algorithm.

This class discusses the number of windows in a building that is 5 cubes high. The side of each cube has one window, and the “skylight” on top of the tower also counts as a window.
