High schoolers discover the scientific method. In this science lesson plan, students explore the steps of the scientific method as they participate in a classroom activity.

In this system of linear inequalities activity, students solve 5 problems with the graphing method and are given 2 examples with multiple steps to follow.

Middle schoolers imagine they are a detective who has been asked to solve the theft of cookies from a jar in the student cafeteria. Students practice using the steps of the scientific method to solve the crime. Finally, middle schoolers...

Students solve systems of equations. For this algebra lesson, students use elimination and substitution to solve for the point of intersection. They use graphing to see where the two lines intersect.

Middle schoolers research the conditions in which molds thrive. They apply the scientific method to develop a hypothesis, conduct research and test results.

Students explore the concept of linear regression. In this linear regression lesson plan, students do a Barbie bungee activity where they collect linear data. Students plot their data using a scatter plot. Students determine a line of...

Students assemble snow goggle models and discuss how snow goggles change the amount of light shining in their eyes.

In this assessment task, learners determine whether a crown with given information is composed of pure gold. The task expects algebraic and numerical solution methods, so unlike Archimedes, no bathtub is necessary.

Youngsters study multiplication facts by manipulating food in order to problem solve. They will use healthy snack items as manipulatives to solve various multiplication equations. Charts, tables, physical models, and so much more are...

This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...

Pupils analyze a pattern of conference tables to determine the number of tables needed and the number of people that can be seated for a given size. Individuals develop general formulas for the two growing number patterns and...

Use inverse trigonometric functions to work with ramps, rabbits, and Talladega. The class models real-world situations with trigonometric functions and solves them using inverses in the 15th installment of a 16-part series. Pupils solve...

Pupils individually determine what they need to know about osteoporosis and how they will find that information. They share their thoughts with a partner before moving on to share with the class. The class arrives at a list of a set of...

Tell the story of the math. Given a graph of a linear system, learners write a story that models the graph before crafting the corresponding functions. Graphs intersect at an estimated point, allowing for different variations in the...

Patterns in math emerge from seemingly random places. Learners explore the patterns for factoring the sum and differences of perfect roots. Analyzing these patterns helps young mathematicians develop the polynomial identities.

It's all about lines when going around. Pupils graph the relationship between the length of a side of a square and its perimeter. Class members explain the origin in context of the side length and perimeter. They compare the graph to the...

In a simple but unique activity, youngsters learn about the history of voting systems. They then collaborate in groups to develop a new honest and consistent voting method. A class-wide poll is taken, evaluating the designs of other...

Scholars first investigate relationships in the side lengths of 30°-60°-90° triangles and 45°-45°-90° triangles. This knowledge then helps them solve problems later in the lesson about special right triangles.

Investigate the application of vector transformations applied to linear systems. Individuals use vectors to transform a linear system translating the solution to the origin. They apply their understanding of vectors, matrices,...

Play a game of capture the points. Young scholars receive a number line with specific points graphed and must write an inequality that captures all the points. The second task of the algebra project is to write an inequality with...

Pupils determine the theoretical probability of winning a game of marbles. Individuals compare the theoretical probability to experimental probability for the same game. They continue on to compare two different probability games.

Class members solve problems to find the whole when given a percent. They  use double line numbers and factors of hundred to help break the 100 percent into equal segments. 

In the first installment of a 21-part module, scholars build on previous understandings of probability to develop the multiplication rule for independent and dependent events. They use the rule to solve contextual problems.

Communication is the key. A dozen sample items require scholars to communicate their reasoning involved in arriving at a solution. The PowerPoint from the Gr. 8 Claim 2 - 4 Item Slide Shows series uses a variety of content to...
