This bundle includes a variety of tasks related to slope and graphing lines. Real-Life connections through analyzing the stock market, investigations of slope-intercept form on DESMOS, and quiz & multiple test options all included. Buying these items as a bundle results in a 25% savings over buying each individually.

This is a fun activity that your students can use to create forced perspective photos while connecting it to similar triangles. This can be done individually or as a group and can be connected to other subjects like Art or Drama as an IDU.

This task can be used as an in-class activity or a Criterion C/D assessment. Task-Specific Clarifications for Criterion D are included. In this activity, the students start by building a catapult out of popsicle sticks, rubber bands, and bottle caps. Then, the students will use their cell phones to slow-motion film launching something to collect x and y-coordinates. To assist with this, I hung meter sticks on the wall at given distances. You could also use the whiteboard to mark given distances.

This task can be used as an in-class task or a Criterion C/D summative assessment. This task comes with Task-Specific Clarifications for Criterion D. In this task, the student analyzes the 2014 Ebola outbreak and uses DESMOS to create 3 increasingly accurate models of the situation. Then, the student justifies the accuracy of the models against each other and the reasonableness of using these models to track a disease.

This task can be used as an in-class activity or as a Criterion D (potentially C as well but would need editing) assessment. In this task, students use printed maps along with the Google Maps distance feature (clear instructions provided) to cover a their country with triangles. With the help of the Laws of Sines and Cosines along with the Area formula, they then calculate an estimated area of the country. Once this is found they then find their percent error and reflect on their strategy. This
