Students practice creating direct variation equations of the form y=mx while playing a game.
This was my first attempt at creating a MarbleSlide activity using Desmos. In this activity students practice creating direct variation equations while trying to launch marbles into stars. I found that this activity really motivates my students to keep trying and to persist. Turning a difficult task into a game allows more of my students to access the material and provide them with instant feedback.
Students explore how Systems of Equations can help solve a real life problem.
My students love In-n-Out. This was a great opportunity to explore how a system of equations can help solve a real world problem. And before your students ask, yes, this was a real problem I had while in line at In-n-Out.
Exploring linear and proportional relationships using equations, tables, and graphs.
My students had a hard time understanding the connection between tables and graphs. So I forced them to see the relationship by creating graphs from tables.
This Desmos activity comes from a classic lesson . Using this page saves instructional time and easily allows students to find patterns in triangle side lengths.
Student can use this to discover a rule that states whether or not it is possible to construct triangles from given lengths.
This was my first attempt at using a Desmos activity in my classroom. It is also the first activity I created myself.
In this activity, students use the Pythagorean Theorem. They will discover that the theorem only works for right triangles. Then use their knowledge to solve some real world problems.
This lesson was created because I noticed that my students were trying to use the Pythagorean Theorem for all sorts of triangles. Acute, Right, and OBTUSE! It occurred to me that I had never told my students that it only worked for right triangles. Then I asked myself, "Why should I tell them when they can discover it for themselves?"
