This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Presley has 18 markers. Her teacher gives her three boxes and asks her to put an equal number of markers in each box. Anthony has 18 markers. His teach...

The Common Core State Standards (CCSS) videos are designed to support states, schools, and teachers in the implementation of selected math standards. Each video is an audiovisual resource that focuses on one or more specific standards through examples and illustrations geared to enhancing understanding. The intent of each content-focused video is to clarify the meaning of the individual standard rather than to be a guide on how to teach each standard, although the examples can be adapted for instructional use.

This is one possible method for using the area model for division.

With this division strategy, students divide by breaking the dividend into its expanded form. Then, students use familiar multiplication facts to divide. It is suggested that this would be the first of three strategies for division (preceding partial quotients and the standard algorithm.

There are two aspects to fluency with division of multi-digit numbers: knowing when it should be applied, and knowing how to compute it. While this task is very straightforward, it represents the kind of problem that sixth graders should be able to recognize and solve relatively quickly.

This short video and interactive assessment activity is designed to teach fourth graders about is it a multiple?.

This video was created by NCDPI. This video examines best practices and research related to developing computational fluency. Teaching strategies and tips are provided.

This lesson unit is intended to help you assess whether students recognize relationships of direct proportion and how well they solve problems that involve proportional reasoning. In particular, it is intended to help you identify those students who: use inappropriate additive strategies in scaling problems, which have a multiplicative structure; rely on piecemeal and inefficient strategies such as doubling, halving, and decomposition, and have not developed a single multiplier strategy for solving proportionality problems; and see multiplication as making numbers bigger, and division as making numbers smaller.

This short video and interactive assessment activity is designed to teach third graders about dividing by 1 digit numbers with illustrations.

Dividing Decimals Animated Review VideoDirect link to Dividing Decimals Animated Review for closed-captionsThis short animated video walks students through the process of dividing with decimals. Two practice problems are presented in the video. The first practice problem has a whole number for the divisor and a number with a decimal for the dividend. The second practice problem has decimals in both the divisor and dividend. This video can be used with students in multiple grade levels to teach dividing decimals as a new concept or as a reteaching tool. You can use either the embed code or direct URL provided below to integrate the Dividing Decimals Animated Review video into your course.The video is closed-captioned and a PDF version of the transcript has been attached.
