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.

In this task, the students are not asked to find an answer, but are asked to analyze word problems and explain their thinking. In the process, they are faced with varying ways of thinking about multiplication.

In this video, a student explains how to use the area model for multiplication. The area model is a multiplication strategy based on decomposing numbers basedon place value.

This is a fun interactive game that allows students to practice their addition, subtraction, and multiplication facts.

This short video and interactive assessment activity is designed to teach third graders about choosing the multiples of a given number up to 12.

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

The purpose of this task is to generate a classroom discussion that helps students synthesize what they have learned about multiplication in previous grades.

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

In this lesson, students will apply their understanding of multiplication of fractions and whole numbers to solve real world problems about a bakery. Students will also use multiplication with decimals (money) to calculate the bakery's earnings.

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 fourth graders about dividing 2 digits by 2 digits with a remainder.
