The activity then leads students through the process of writing a system of linear equations to represent the scenario . Edited with love by Desmos. Polygraph: Functions & Relations Designed to spark vocabulary-rich conversations about functions and relations. There are multiple ways to solve a system, including: graphing, substitution, and elimination. Traveling to School Students consider 4 students and their trips to school comparing their distance traveled over time. Which result is more likelyred or blue? Likewise, a solution to a system of linear equations can be interpreted in two ways: (a) graphically, as a point that lies on each line in the system, and (b) algebraically, as an ordered pair that satisfies each equation in the system. (added 11/4/16). In that case, you may find the following. Inspired by OpenMiddle.com, this brief warm-up experience is designed to help students apply the correct order of operations to numerical expressions that contain exponents. Lines, Transversals, and Angles Students explore the relationship among angles formed by a transversal and a system of two lines. Then let students play again and experience the power of that formal language. Key vocabulary that may appear in student questions includes: rate of change, increasing, decreasing, constant, velocity, and intercept. We hope it can be a valuable resource for those who want to stay up to date on the latest tools and activities, as well as an easy way to get caught up after a break. There are multiple ways to solve a system, including: graphing, substitution, and elimination. Students practice asking questions using vocabulary such as: acute angle, obtuse angle, right angle, complementary angles, supplementary angles, corresponding angles, vertical angles, alternate interior angles, alternate exterior angles, congruent angles, transversal, parallel lines, perpendicular lines. There are four sorts that are all very similar to each other; you may wish to assign different sorts to different groups. In this activity, students use Desmos-powered geoboards to explore length and to further develop their proficiency with the Pythagorean relationship. Edited with love by Nathan Kraft. Introduction. They reflect on these choices, and apply their learning by creating their own equations and tables of values that fall into each category. Sum and Differences on the Number LineIn this short activity, students explore the relationships among a + b, a b and b a on a number line when the precise values of "a" and "b" are unknown, but their signs are known. 30-45 minutes. Segmented Functionsby Katina Vlastos.

These challenges can be used with any level from Algebra 1 through and beyond Calculus. In this brief card sort activity, students sort equations according to the property they illustrate (commutative, associative, identity, and distributive). String Art 2.0 Students will be able to use slope intercept form and limit on the domain to create string art designs. (added 8/25/16), by mathycathy. ), Number System / Expressions and Equations / Exponents (gr 8), One Variable Inequalities / Linear Inequalities / Systems of Inequalities, Cool Extensions / Advanced Skills Other (gr 8). Student History Page From the class roster page, you can view an individual student's activity history for the class. Students (1) describe and execute dilations using reductions, enlargements, and scale factor; (2) perform error analysis, critiquing a classmate's mistake, and then fixing it. Some of the challenges are very difficult to complete using a single equation, but all should be possible to complete using a number of linear equations. Thompson Cigar Auction,
