Slide 25: Full shading of the domain as was done in previous slides would be useful. A student typing pi/2 would get “correct” feedback as soon as they type pi. Slide 24: Edit the correctness check to require a submitted. Slide 20: I suggest setting the initialTool to the line tool Slide 18: Maybe make theta a unique color and specify in the directions. Currently, “Correct!” displays as soon as they click the correct combination whether they click Submit or not. DOMAIN (x) How much does a large plain cheese pizza cost. Slide 11 (maybe others): you may want to use the. Check Consider the two functions: Write the domain and range of the graph shown using inequalities. Also, don’t know if you’ve taught (or been explicit about) the relevance of a dashed line versus a solid line as the domain is shown. Slide 9: the domain doesn’t adjust in the graph if a bracket is used. Slide 2 (and 16) is a beautiful animation, but could be extremely confusing for students. It jumps a lot if the graph isn’t fully visible in the screen. Furthermore, Desmos categorizes all of their activities into four buckets: Introduction, Practice, Development, and Application to help determine which activities would fit best in your unit.I think you should direct students in the first slide to adjust the zoom so that the whole graph is shown. In this activity, describe in words the domain and range of. This was just a small snippet of all of the activities that Desmos has to offer. It assumes your students have encountered these terms, and gives them interesting cases to consider. Transformation Shapes – Specifically for middle school or geometry students, use this activity to have students internalize transformation vocabulary: slide, rotate, reflect, etc. One plan increases by $100 each day, while another grows by doubling the previous day’s payment.” 9. “In this twist on a classic activity, students compare linear and exponential growth in the context of daily payments. Exponential FunctionsĪvi and Benita’s Repair Shop – This is an engaging way to introduce exponential growth to students. Match My Parabola – “In this activity, students work through a series of scaffolded quadratic graphing challenges to develop their proficiency with standard, vertex, factored, and other quadratic function forms.” 8. This is a quick self-check or error analysis built into several of these activities. Side note: One of my favorite features is the “Share With Class” feature that allows students to see 2-3 responses from other students on their screen. Use this to review the unit or for the rest of the class when you are pulling a small group. Solutions to Systems of Equations – This activity hits on everything students need to know about solving systems of equations graphically, with substitution, or with elimination. Students will also interpret the parameters of their equation in context. Lego Prices – I love this activity! In this activity, students use sliders to explore the relationship between price and number of pieces for various Star Wars LEGO sets and to make several predictions based on that model. Marble Slide Activity – This game allows students to explore the changes to a line when the slope and the y-intercept are altered. Use curly braces at the end of an expression to add a domain or range restriction in seconds. They begin with an informal exploration of domain and range using a graph, and build up to representing the domain and range of piecewise functions using inequalities.” 4. Furthermore, students are asked to defend their answers and create their own examples of functions.ĭomain and Range Introduction Activity – “In this introduction to domain and range, students practice finding the domain and range of piecewise functions. Properties of Functionsįunction Card Sort Practice – In this activity, students would differentiate between graphs, stories, and equations that are functions or not functions. Then they’ll use those numerical expressions to help them write an expression with variables.” 3. Pool Border Problem – “In this exploration activity, students will first construct expressions with numbers to determine the number of tiles that border a pool.
