Students will explore multi-digit numbers and the relationship between ones, tens and hundreds; a digit in one place is 10x the digit in the place to its right. Students will use their bodies to represent digits in multi-digit numbers up to the hundredths place and compare these numbers using <, =, >. Students will use their bodies as multi-digit numbers to add and subtract.

Students love to represent! In this lesson they will compare and explore multi-digit whole numbers to understand various ways of reading and writing numbers

This video lesson demonstrates long division of a two-digit number by a one-digit number, where the answer will contain a repeating decimal. It is 1 of 10 in the series titled "Dividing Two-Digit Numbers by One-Digit Numbers Repeating." Includes short multiple-choice quiz. [2:07]

This video demonstrates division of two-digit numbers by two- or three-digit numbers. This lesson is 1 of 19 in the series titled "Dividing Two-Digit Numbers by Two or Three-Digit Numbers." Includes short multiple-choice quiz. [4:19]

In this video, the instructor demonstrates how his "Exploding Dots" method of division reflects the standard algorithm of long division. He presents side-by-side examples of 276 divided by 12 using the two methods and explains how they are actually doing the same things. The video is accompanied by a written explanation of the lesson. This lesson is part of a larger module on the "Exploding Dots" technique, which can be accessed under the "Courses" tab at the top. [6:03]

In this 43-day module, students use place value understanding and visual representations to solve multiplication and division problems with multi-digit numbers. As a key area of focus for Grade 4, this module moves slowly but comprehensively to develop students’ ability to reason about the methods and models chosen to solve problems with multi-digit factors and dividends.
