This task provides students the opportunity to identify a mistake in reasoning related to the relationship between multiplication and division.

CK-12 Algebra Explorations is a hands-on series of activities that guides students from Pre-K to Grade 7 through algebraic concepts.

Students will work with a partner to write, solve, check, and animate a division story problem based on a division expression using a sharing model.

Remember your multiplication tables? ... me neither. Brush up on your multiplication, division, and factoring skills with this exciting game. No calculators allowed! The students will be given mutiplication and division problems which they must answer. They also have the option of being given a number then stating the factors of how that number was attained using either multiplication or division.

This short video and interactive assessment activity is designed to teach third graders about place value problems involving grouping of items.

Students acquire a basic understanding of the science and engineering of space travel as well as a brief history of space exploration. They learn about the scientists and engineers who made space travel possible and briefly examine some famous space missions. Finally, they learn the basics of rocket science (Newton's third law of motion), the main components of rockets and the U.S. space shuttle, and how engineers are involved in creating and launching spacecraft.

This roadmap begins with a KWL that covers the relationship between multiplication and division . Then it moves to informational readings and a video for students to use
to gather information to complete a venn diagram and the KWL. The roadmap finishes with an assessment solving a division problem using multiplication and explaining the process.

The Illustrative Mathematics Project provides guidance to states, assessment consortia, testing companies, and curriculum developers by illustrating the range and types of mathematical work that students will experience in a faithful implementation of the Common Core State Standards, and by publishing other tools that support implementation of the standards.
