Students investigate geometric relationship using conjecture about linear pairs and vertical angles. In this geometry lesson, students apply their theorems and previous geometry knowledge to solve for and find angles of linear...

Students measure angles using a plane table kit. In this geometry lesson, students use trigonometric identities to find the values of the length of a football field.

Using the TI-Nspire calculator, statisicians identify outliers and their effect on the least-squares regression line. In finding the line of best fit, they determine what points will affect the least squares regressions and what points...

A four-page resource walks learners through the basics of multiplying fractions. The handout is very visual with many diagrams in various colors. By the end of the lesson, learners are given an opportunity to multiply whole numbers with...

Learners use the Frayer model during problem solving. In this problem solving lesson, they examine multiple methods of data collection to solve real world problems. Resources are provided.

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...

You hit the jackpot with a fun lesson! Peak your pupils' interest with a lesson calculating the probability of poker hands. A video shows the different types of possible hands when given a specific hand and one card to draw. 

Work with the class to investigate the concept of dividing decimals. They will use a variety of problem-solving skills in order to practice the operation of division. The teacher can use the dialogue to guide learners through the various...

High schoolers find the volume of pyramids and cones. In this volume of pyramids and cones lesson, learners explore the relationship between the volumes of prisms and pyramids. They investigate the relationship between pyramids and cones.

An interactive lesson helps individuals learn to graph inequalities in two variables. Scholars can adjust the interactive to present the inequalities in standard or slope-intercept form.

Students study the scientific evidence about carbon dioxide emissions. They learn to calculate the amount of energy used by different appliances. They complete a worksheet which analyzes the amount of energy that their home uses.

There are a number of activities here where learners collect and record data, as well as, activities where the likelihood of an event happening is calculated given the experimental probability. Young statisticians organize information...

In this algebra worksheet, students calculate the maximum and minimum of a shaded region. They identify the boundaries and their vertices's. There are 2 problems.

Calculate the answers to problems that are multiples of ten to help your class discern patterns in the zeros and learn to sequence. Each person receives a 10,000 chart, but s/he must discover that on their own through estimation and...

Ready to study inequalities with your class? Use this worksheet to solve multi-step inequalities and graph the solutions. The document would be great to use as a study guide as you present the material, or could easily be modified and...

Here is a lesson that starts with having geometers translate points using compass directions into an accurate picture of the problem. Then they must use their knowledge of the Pythagorean theorem or similar triangles to solve. This makes...
