Everything on Quadratics
Use this activity to help your students discover and practice Quadratics. It covers graphing, quadratic formula, factoring, zeroes, roots, solutions, x-intercepts, axis of symmetry, min/max, increasing/decreasing intervals, and the vertex. Everything is on one page, so students learn that there are multiple ways to find the zeroes of a quadratic. Their knowledge allows them to pick the best method. This pack includes 2 versions, 16 total problems, all problems worked out in the included key.

Modeling the Business Cycle with Trig Functions: Activity and Data Set
In this lab, students analyze GDP data from five fictional countries. To complete the activity, students: -- create scatterplots of their data using desmos.com/calculator (or other graphing utility) -- use their data sets to compute the parameters of underlying sinusoidal functions and use Desmos to compare their estimates to the data sets -- interpret the parameters of their equations in context by describing how the economies of each country compare and contrast to each other. -- are challenge

Linear and quadratic functions - performance task
This is a media-based performance task. It requires that students watch a YouTube video which will engage them in answering the questions in the handout. More importantly, students will increase their understanding of linear vs. quadratic functions by evaluating functions for various points. They will also make a connection about how the degree of the function determines the shape of its graph.

Target Toss Regression Lab: Linear/Exponential/Power Models (AP Stats/Precalc)
Aim - Toss - Model: Target Toss Lab for Linear, Exponential & Power (AP Precalculus, Algebra 2, AP Statistics)Bring regression to life in AP Statistics and Precalculus with this target toss lab! Students collect real data, then compare linear, exponential, and power models using log transformations, residuals, and r². It's a hands-on, data-rich investigation. In this safe “candy toss” lab, students collect data at increasing distances, compute success rates as proportions, and use log transfo

Scatterplots: Linear Regression Line of Best Fit:Forearms and Height (Editable)
After teaching my students about scatterplots, correlation, and the line of best fit, I take a day for them to do a hands-on lab, in which they measure their height (in inches) and their forearm length (from the tip of their elbow, to the bony point on their wrist), and we plot the class data, write the equation of the line of best fit, and then use the equation generated both forwards and backwards. They will need 45 minutes to an hour to do this in class.
Some years, the data have very littl

Math Lab:Exponential Functions and Seed Overproduction vs Time/DISTANCE LEARNING
My students totally enjoy doing the following math lab! They invariably find it to be both fun to do as well as informative. They readily relate to discussions within.
* Students work with a partner
* Students begin by a brief discussion about seed overproduction
* Students are provided with assumptions used to complete the lab
* Students work collaboratively to determine the number of seeds in a bell pepper
* Students find the average number of seeds in a bell pepper using the totals

AP Precalculus Exponential Modeling Lab | FRQ 2 Style Cooling Performance Task
Make AP Precalculus exponential modeling feel meaningful, hands-on, and worth the class time with this Holiday Café Cooling Lab! In this Unit 2 performance task, students collect real cooling data from hot water, transform the data by subtracting room temperature, build a vertically shifted exponential decay model, and interpret the model in context.This activity is designed to support AP Precalculus FRQ 2-style non-periodic modeling skills. Students solve for parameters (a) and (b), interpret a

Coulomb's Law Inquiry Lab with Magnets
Coulomb's law requires expensive and delicate equipment. This chape and easy version is a clever and innovative inquiry lab that is appropriate for on-level, pre-AP, honors, and AP physics.
Students work in groups of 4 to determine the effect of distance on the repulsive force between two similar magnets. Disk magnets are best, neodymium disk magnets even better, but any small magnets will work.
Student express surprise at feeling the force of repulsion between the magnets. This is measured

Algebra Research Project
In this bivariate data analysis project, students will develop their own correlation-based study, design a data collection method, and calculate and present on their results. Students will need to have an understanding of data collection, research methods, scatterplots, line of best fit, regression, and correlation analysis to complete this project. In-class work time should minimum be 2 days, max 4, and presentations should take about 2 class days. Since grading happens during presentations, th
