Launching Into Expressions and Equations

Teacher's Guide

Launching Into Expressions and Equations is an online, interactive tool designed to engage middle school students in developing an understanding of expressions and equations through a focus on variables and scientific notation. The interactive tool also highlights the value of math in real-world situations and careers, encouraging students to envision themselves as astronauts using math for space exploration.

The interactive tool includes two modules that support both the Common Core State Standards for Mathematics (including Practice Standards) as well as the National Council for Teachers of Mathematics (NCTM) Principles and Standards:

MISSION TO MARS covers variables and is recommended for grades 6–7 or as review for grade 8.
INTERNATIONAL SPACE STATION covers scientific notation and is recommended for grade 8 or for advanced students in earlier grades.
At your discretion, the modules can also be used sequentially for either reinforcement or extra challenge. The tool is equipped with hints, as needed, to provide support. Each question also includes an optional “Bonus Mission Task” question to push students’ thinking further. The Using the Tool page supports students as well.

Ideas for Classroom Use

Accompanying Interactive Lesson: The tool is integrated into an interactive lesson on expressions and equations. A series of printable activity sheets can also be used in place of, or to complement, this online tool.
Whole-Class Instruction: The tool can be used on a whiteboard as part of a whole-class introductory lesson on expressions and equations.
In-Class Project or Homework: Individual students or small groups can be assigned a module(s) to work on independently.
Extend Student Thinking: See the Using the Tool page.
ELA Connection: The classroom edition of The Martian by Andy Weir tells the story of an astronaut stranded on Mars and his fight to survive. Hint: He relies on his knowledge of math and science!

Related Lessons and Activity Sheets

Solving the Unknown with Algebra: Students apply mathematical thinking to practice pre-algebra skills, including using formulas, solving for unknowns, and manipulating equations.

More Interactive Tools

Ratio Design Challenge: This interactive tool on ratios and unit rate enables the student user to construct scale designs of an architectural venue. The scenes come alive as students apply ratio concepts to build a baseball stadium and amusement park, and unit rate concepts to build an aquarium research center.
Data Sampling—Representing Many by Sampling Some: This highly interactive and adjustable tool—in which students survey a fictional town about policy issues of interest to teens—gives students the opportunity to experiment with why it is important to select representative samples when drawing conclusions about a population.
Data Displayer: Use this data-analysis classroom tool with your students to calculate and graph data. Functions include: mean, median, and mode; box-and-whisker plot; scatterplot; and standard deviation. Preset data is provided (in the themes of movies, sports, and agriculture), and custom data can be entered as well.
Probability Lab and Probabilities Tour: In the Probability Lab, students explore the difference between theoretical probability and experimental probability by running their own probability experiments. In the Probabilities Tour, students will consider both theoretical probability and potential financial rewards to help plan a concert tour for a band.
