(added 9/18/16), Students often confuse the concepts of "square" and "square root". In Marble Slides, such as https://teacher.desmos.com/marbleslides-parabolas, students are able to manipulate their graphs by changing specific constants in the given equation. Quizzes with auto-grading, and real-time student data. In this activity, students build coordinate plane proficiency through a guess-the-location-style game. Students explore the relationship between college costs and time. In this activity, students explore the idea of "steepness" of line segments. (added 8/2/17), Interpreting Pointsby Paul Jorgens. A short review on linear systems that taps into student intuition and their understanding of: slope-intercept form attributes of a system with one solution attributes of a system with no solution (10/9/16). Traveling to School Students consider 4 students and their trips to school comparing their distance traveled over time. Proportional / Linear, Walking and Wondering Students gather and analyze walking data (distance in feet compared to time in seconds), write equations to represent this distance-time relationship, and compare their own walking rates to others through multiple representations (numerical, graphical, and algebraic).

(added 12/19/17), Talking TimeThis activity helps students understand different ways that people talk about time. They examine actual data from 1984-2012 and notice changes in the trend, reflecting on the strength and weakness of the linear model. Key vocabulary that may appear in student questions includes: parallel, intersect, solution, quadrant, axis, vertical, horizontal, slanted, increasing, and decreasing. A variety of math levels, including elementary, would benefit from utilizing card sorts. Finally, students practice solving equations using substitution and elimination. In this proportional reasoning activity, students explore the relationship between circle area, sector area, and sector angle. In this activity, students explore the idea of "steepness" of line segments. If an instructor notices a misconception performed by numerous pupils, the activity may be paused. It is not expected that students will complete all of the challenges. by Desmos. This thread shows some examples. (added 10/9/16). Teachers will see which time formats are easier and harder for students. We recommend you solve the challenges yourself before assigning this activity. (added 2/9/17).
