Students linearize data to determine if an exponential model is suitable. In this linearizing data to determine if an exponential model is suitable lesson plan, students graph the residuals of sets of data that appear to have an...

Seventh graders gather data to determine the relationships between the base and height of rectangles with fixed perimeters and express the relationships using words and symbols. Students build rectangles with pipe cleaners. They create...

In this food web instructional activity, students create a food web matrix and answer short answer questions about the food chain according to the matrix. Students complete 7 short answer questions.

Introduces your class to random processes in networks with an activity that uses information about disease spread using the susceptible, infectious, resistant (SIR) model. Participants determine whether a susceptible person becomes...

Do you know how the population has grown of your community? Can you predict the population over the next half century? Can we find an algebraic model that matches our data? These along with many more questions can be researched by...

Solve problems using integration and derivatives. By using calculus, learners will analyze graphs to find the extrema and change in behavior. They then will identify the end behavior using the derivatives. Activities and handouts are...

How can you see a number in nature? Here, learners discover both Fibonacci numbers and the golden ratio by exploring a number of different resources.  Note: Some of the resources are older and may be missing some of the links, but...

Fifth graders work in groups to investigate the proper use of a graph during a schoolyard ecology project. The challenge of the project is for students to choose the proper form of a graph. They gather data and conduct analysis with the...

Upper elementary and middle schoolers work with the concept of probability. They are introduced to the concept of chaos. Learners graph and analyze using a line plot, work with mean, and are introduced to the concept of variance.

There are a number of activities here that look at representing data in different ways. One activity, has young data analysts conduct a class survey regarding a new radio station, summarize a data set, and use central tendencies to...

Students identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.

Students investigate ways to enhance an object's flying ability.  In this model construction lesson, students construct two paper airplanes, one of which is twice as big as the first.  Students compare and contrast the two...

Kindergartners are introduced to basic shapes. Learners spend 45 minutes a day in geometry centers carrying out the activities outlined in this ambitious plan. There are games, hands-on activities, interactive websites, art projects,...

In this second grade lesson your class will practice telling time. The goal is to tell time to five minutes using an analog clock. Your young students count by 5 minute intervals and discuss elapsed time. 

Help your young mathematicians completely master 10 by practicing one-to-one correspondence, number recognition, and recording numbers displayed. They make 10 with groups of two-different colored cubes and color in 10-frames to show how...

If you are looking for a simple way to review equivalent fractions, this is a great resource. Using a visual means and a series of examples, learners review this skill. There is a worksheet provided and a prompt to encourage pupils to...

Most young mathematicians are aware that the planets don’t orbit the sun in a circle but rather as an ellipse, but have never studied this interesting feature. This resource looks at the planetary orbits in more detail and helps learners...

Students practice plotting functions on the Cartesian coordinate plane while participating in a discussion about the Possible Or Not worksheet/activity. Students also use the Impossible Graphs worksheet to practice reading a graph,...

Use this series of activities to introduce learners to graphing functions. They graph both linear and quadratic equations by hand and with a Graph Sketcher Tool. Several imbedded links and handouts are included in the lesson.

Help your kindergarteners discover new number-sense concepts and to compose and decompose numbers. Though the resource contains no procedural details, the assessment tool (which you can find in the "printer friendly version") has...

Use algebra to solve real world problems. Mathematicians practice use of graphs, tables, and linear functions to solve a problem regarding mp3 purchase plans. They work in groups to solve the problem and present their findings and...

Students differentiate between exponential growth and decay. In this algebra activity, students solve exponential equations using properties of exponents. They use the Ti calculator to graph and analyze their functions.

Use this worksheet to write equations in both point-slope form and slope-intercept form. Start by writing equations given one point and the slope and finish by writing equations given two points and a few real-world applications. The...

This basic handout would be good for skills practice or a review of parallel and perpendicular lines. Review the definitions, then practice writing equations of lines that pass through a specific point and are either parallel or...
