Pupils explore the concepts of graphs, correlations, line of best fit, and the dipstick problem. In this graph, correlation, line of best fit and dipstick problem lesson, students solve problems on the above mentioned topics. Pupils...

Students analyze data and identify the mean. In this probability lesson, students log data in the TI and construct scatter plots from the data. They identify properties of a scatterplot.

Young scholars identify the line of best fit. In this statistics lesson, students analyze graphs and plots to identify positive, negative or no correlation. They find the line of best fit for different scatter plots.

Pupils explore the law of reflection. Through experimentation and problem solving, they collect and analyze data pertaining to reflection. The data is plotted on a graph and formulas for calculating the x and y values are evaluated.

Students investigate the concentration level of solutions. In this math/science lesson, students identify three different ionic compounds. They predict the conductivity of each using their collected data.

You may be able to see patterns visually, but mathematics quantifies them. Here learners find correlation in scatterplots and write equations to represent that relationship. They fit a line to the data, find two points on the line, and...

Students explore how the population decreased in native cultures.

Using a data collection device to collect data regarding a bouncing ball, students use various features on graphing calculators to experiment with the parameters of the vertex form of the parabola and their effect on the shape of the...

High schoolers analyze the vertex form of a parabola and find an approximate fit of a model. They explain the quadratic parabola function and its properties by developing quadratic models. They use translation and dilation to change the...

High Schoolers explore the concept of exponential reflections. They use their Ti-Nspire to reflect the natural logarithm function over the line y=x. Learners repeat the process using different exponential functions using a slider.

Turn up the heat! Young mathematicians develop models to represent different climates and collect temperature data. They analyze the data with regression and residual applications. Using that information, they make conclusions about...

Find that slope! This video does an excellent job of demonstrating how to use the slope formula to find the slope of a line using two points. The instructor first reviews the definition of slope of a line, then works three problems using...

This highly scaffolded, summative assessment tasks learners to choose the model that represents the height of a bouncing basketball given the data in graph and table form. Learners then use the model to answer questions about the...

How can you safely model exponential growth and decay? A hands-on activity uses candies to model not only exponential decay, but also exponential growth. Exponential equations are fitted by hand and by use of a calculator...

Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to...

Learners explore the concept of logarithms.  In this logarithms instructional activity, students discuss the logarithm properties.  Learners use linear functions as a basis to develop the logarithm properites by substituting...

Student apply linear relationships to the real world. They use Ken and Barbie dolls and experiment to find the line of best fit. They collect data, analyze data, and make predictions from it. The students also use Microsoft Power Point...

Middle and high schoolers explore the concept of linear modelling.  In this linear modelling lesson, pupils find the line of best fit for life expectancy data of Canadians. They compare life expectancies of men and women, and find...

Is there a correlation between the number of coffee shops and the amount of crime in a given area? For this quick exercise, your class will examine the data, interpret the results, and discuss their conclusion. Concepts covered include...

What is the financial benefit for attending a community college for the first two years before transferring to a four-year college? The second part of the educational lesson asks young scholars to explore this question through data...

Learners explore reflection of polygons on a coordinate plane. They examine the relationships that exist between corresponding points and sides. 

High schoolers investigate linear, quadratic and exponential equations using the TI calculator. They identify relation and functions using ordered pairs, graph the data, analyze the data, and relate it to real-world situations.

Given the least squares regression line, interpret the slope and intercept in the context of the relationship between texting and GPA. Although this task is short and looks simple, some subtle points can be brought to light in a...
