# Module 4: Multiplying and Dividing Multi-Digit Numbers - Course Guide

## Module Overview:

In this module students will learn about multiplying different digit numbers by one-digit numbers, multiplying by numbers with more than 1 digit, and solving problems with multiplication. Students will learn about dividing by one-digit numbers and dividing by numbers with two digits. Students will learn how to use partial quotients to solve long division problems, how to use partial quotients for powers other than 10, and how to use traditional long division and how it can be applied to problems.

## Module Video Questions:

When a student watches a video take time to ask them questions about what they watched. Suggested questions for the videos in this module are listed here. Suggestion: Have the student watch the entire video first all the way through. Then have them watch the video a second time, as they watch it pause the video and ask the questions.

## Module Suggested Read Aloud Books:

Take time to read to your student or have them read aloud to you. Read a different book each day. While reading the book point out concepts being taught. You may purchase these books or find them at your local library. Suggested things to discuss while reading the book:

• What is the main idea?
• What are three things new you learned?
• How does this book relate to what you are learning about?
