Force your way to a better understanding of vectors! Pairs of young scholars work together to apply the right amount of force to move an object along a straight line vector. They use calculations to determine the magnitude and direction...

Predict outcomes using linear models. Young mathematicians strengthen their understanding of slope and linear models using a hands-on activity. They monitor the dissolving rate of bouillon cubes, graph their data, and make predictions...

Create a linear versus exponential debate. An exploratory activity asks scholars to analyze population data and determine the best type of function to model the pattern. The data represents populations from five continents.

Tuition costs are always on the rise. Help your classes quantify this change using real tuition data. Future college scholars analyze data from 2012 and compare it to current tuition rates with a graphical analysis.

Explore linear inequalities in a contextual situation. Using data from the first lesson of the series, groups graph linear inequalities to predict future shooting percentages. Their work focuses on defining regions and relating their...

It's the one day your classes get to 'shoot' their trash into the can! Scholars collect data related to shooting percentages to analyze. As they move farther from the basket, their percentages change, and a linear model emerges.

Parallel lines and transversals work together to create unique angle pairs. An inquiry-based activity allows scholars to explore these relationships and give them each a name. Flashcards allow them to study the new vocabulary.

Take a functional view of appliances. Pairs revisit functions by looking at appliances and determining whether each is a function. Groups create definitions of function, range, and domain and use them to identify functions.
