All triangles have some things in common. Using these properties of triangles, learners find missing angle measures. Scholars use the Angle Sum Property and properties of special triangles throughout the lesson.

The shortest distance between two points is a straight line. Learners use the Pythagorean Theorem to develop a formula to find that distance. They then find the midpoint using an average formula. 

Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

Lateral area and surface area are simple concepts, but calculating them is not as easy! Using formulas, learners calculate lateral area and surface area for the same three-dimensional figures. The resource discusses the formula variables...

Pie isn't just for eating! Scholars learn to create pie charts and circle graphs to represent data. Given raw data, learners determine the percent of the whole for each category and then figure out the degree of the circle that percent...

The middle of the data is important, but what about the rest of it? The lesson shows learners the importance of the range, quartiles, and extreme values. Pupils practice finding each of these values from given data sets.

Some say that you can make statistics say whatever you want. It is important for learners to recognize these biases. Pupils learn about sample bias and the different types of samples.

Circles, and triangles, and tangents, oh my! In the assessment task, learners first answer questions leading to the radius of an inscribed circle for a given right triangle. They then use the result to independently determine the...

Sugar rush! For this assessment task, learners interpret points on a scatter plot representing price versus weight for bags of sugar. They then determine the bag that represents the best value.

So many different kinds of equations and inequalities! Learners solve equations and inequalities with quadratics and other higher-order polynomials. They then classify the equations based on the number of solutions.

Could you carry a million dollars in $1 bills? As a middle school assessment task, learners investigate different questions regarding a million dollars. They then determine how long it would take to make a million dollars, how...

It's a small world after all. In the middle school assessment task, learners use data that imagines there are only 100 people in the world to answer questions about population demographics. Young mathematicians use ratio and proportional...

Learners first create designs for greeting cards by applying transformations of shapes on a coordinate plane, and then determine a sequence of transformations that produces a given design.

As a middle school assessment task, learners first two write equations representing their purchase of chips and candy bars. They then solve the system of equations to find the price of each item.

"Ordinary" bicycles are not so ordinary. Learners use given information to determine the circumference of wheels for a historic Ordinary or Penny Farthing bicycle. Pupils then determine the number of times each wheel turns when the...

Have some fun with functions with a short activity that asks learners to first sort scatter plot in terms of their correlation. They then sort graphs of different types of functions in terms of key features, such as slope.

Learners first determine the slope-intercept and standard forms of inequalities given graphs, and then determine key features of the graphs.

Life isn't fair ... like inequalities. After first reviewing inequality symbols and how to read inequality statements, learners discover how to solve one-step inequalities and graph their solution sets.

As a middle school assessment task, learners first examine line graphs of monthly temperatures for two locations, and then match box plots to each line plot.

Parallel parking might be difficult, but finding parallel lines is fairly simple. In this lesson plan, learners first complete an assessment task involving parallel and perpendicular lines in the coordinate plane. Individuals then take...

Practice adding and subtracting positive and negative numbers with a forty-problem integers worksheet.

Learners conduct an experiment to develop a cooling curve for pizza. They consider how this affects pizza delivery in terms of packing material, distance, and delivery routes.

Mississippi has both the highest obesity and poverty rate in the US. Does the rest of the data show a correlation between the poverty and obesity rate in a state? Learners tackle this question as they practice their skills of regression....

The more you text, the less you study. Have classes test this hypothesis or another question related to text messages. Using real data, learners use technology to create a scatter plot and calculate a regression line. They create a dot...
