Work it out — find the average time clients spend at a gym. Pupils use a table of random digits to collect a sample of times fitness buffs are working out. The scholars use their random sample to calculate an estimate of the mean of the...

Increase your sample and increase your accuracy! Scholars complete an activity that compares sample size to variability in results. Learners realize that the greater the sample size, the smaller the range in the distribution of sample...

How well does your garden grow? Model the growth of dahlias with nonlinear functions. In the lesson, scholars build on their understanding of mathematical models with nonlinear models. They look at dahlias growing in compost and...

A math model is a good model. A slide show presents 10 sample items on modeling and data analysis. Items from Smarter Balanced illustrate different ways that Claim 4 may be assessed on the 8th grade math assessment. The presentation is...

Two real-world activities to practice adding, subtracting and multiplying matrices to problem solve. Data from several Pro football quarterbacks is used in one activity to make some predictions based on their stats. Then the class takes...

Where does our garbage go? What is the difference between a recyclable and non-recyclable item? Pose these important, but often overlooked, questions to your class and invite them to consider the lasting and damaging effects of the...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

What linear equation will fit this data, and how close is it? Through discussion and partner work, young mathematicians learn the procedure to determine a regression line in order to make predictions from the data. 

Pupils figure out how to be resourceful when tasked with finding the area of a triangle knowing nothing but its endpoints. Beginning by exploring and decomposing a triangle, learners find the perimeter and area of a triangle. They...

Seventh graders solve and complete 12 different problems that include graphing and using multi-steps to solve. First, they solve each multi-step linear non-compound inequality with the given values. Then, pupils graph each solution given...

Students investigate linear programming using the TI. In this algebra lesson, students collaborate and graph linear inequalities on a TI. They analyze their data and present it to the class.

Students investigate geo-profiling.  In this secondary mathematics lesson, students use geo-profiling to determine the most probable location of a criminal.  Students find the centroid of a polygon where the vertices represent...

It may be tricky for a young mind to conceptualize that less than 1% of all water on earth is useable for humans to drink. Simulating the amount of fresh water available on earth by removing measured amounts of water from a five-gallon...

Students analyze the sliding of boxes along a warehouse floor. In this algebra lesson, students connect math and physics by calculating the friction created by the sliding of each box. They develop faster method to move the box, based on...

Students use graphs and plots to measure the basal area and stocking levels.  For this graphing instructional activity students work in the field the use their data to help them complete a lab activity. 

Young scholars investigate the concept of using quadratic data to plot coordinates on a plane. They also apply the quadratic formula for a variety of problems with the help of a graphing calculator to draw the parabola for given...

Pupils play a game and collect data for their graph. In this algebra instructional activity, students solve quadratic equations and identify properties of their graph. They describe the pattern created by the graph and the game.

Students use the Geometer's Sketchpad to illustrate possible answers to a parallelogram problem. As a class, they discuss the point-slope and linear equation forms. Individually, students solve their equations and check the results on...

Eighth graders investigate the input/output model for building function tables. From the data, 8th graders connect tables, graphs, function rules, and equations in one variable. They work backwards to determine function rules for given...

For this graphing systems of inequalities worksheet, students solve and graph 4 inequalities with the help of a computer. Students solve 2 more systems of inequalities using the calculator.

Students identify the basic transformations of parent functions. They use their graphing calculator to create a transformation booklet by folding a sheet of computer paper in half and stapling along the folded edge.

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

Students access prior knowledge of butterflies.  In this butterfly instructional activity, students create butterflies and compare and contrast their butterflies. Students describe the various body parts.
