Students derive the six trigonometric identities. In this trigonometry lesson, students find the ratios of sine, cosine and tangent using the right triangle. They use properties of the Pythagorean Theorem to find the trig identities.

Students consider perimeter and circumference. In this lesson plan on perimeter, students will determine relationships between perimeter and circumference using real life examples.

Students calculate the shortest distance of various scenarios. For this algebra lesson, students interpret graphs of optimization problems. They use a graphing calculator to assist them in graphing and making predictions.

Students investigate points and angle bisectors. In this geometry lesson, students define angles, bisectors and perpendicular bisectors. They analyze angles and bisectors using Cabri software.

Students find the different ratios of a triangle. In this geometry lesson, students use the Pythagorean Theorem to solve for missing sides and angles on a right triangle. They use a robot to create a right triangle.

Students find the area of polygons.  In this area of polygons lesson, students find the area of parallelograms, rectangles, squares, and other polygons.  They identify each given figure and determine the appropriate formula...

Pupils find the mean, median and mode. In hs statistics instructional activity, students collect, plot and analyze data. The identify the effect the central tendency have on the data and line.

Young scholars collect data on a robot and relate the behavior to prove there is an infinite minute set of numbers. In this algebra lesson plan, students verify that there is always a number between two numbers. They analyze and...

Students practice making and interpreting pie graphs so they are better able to decide if a pie chart is the appropriate form of display. Students examine included overheads of different pie charts, and directions on how to make pie...

In this exploring projective geometry worksheet, students use computer software for instruction, then answer 9 questions about 3D drawings.

Students explore the definitions of segment and distance. They perform hands-on activities to form a segment and examine distance. Following teacher guidance, they construct congruent line segments. Independently, they find the...

Seventh graders explore surface area. They study the difference between two and three-dimensional objects. The teacher leads a discussion about finding the surface area of different size cubes. In pairs, 7th graders use graph paper to...

Students explore geometry by participating in a class card game. For this triangle lesson, students utilize playing cards with shapes on them which they group up and discard, similar to "Old Maid." Students complete a worksheet and...

Students identify the properties of chords. In this geometry lesson, students multiply chord segments to find the solution to their problem. They construct two chords that cross on  a circles.

Learners use the point slope formula to calculate the slope and equation of a line. In this algebra lesson, students identify point on a coordinate plane using a robot. They differentiate between the different quadrants a they follow the...

Students derive the six trigonometric identities. In this trigonometry lesson, students review the parts of a right triangle and use the Pythagorean theorem as a guide to find the trig identities. They find sine, cosine and tangent ratios.

Learners are introduced to the concept of ratios. In groups, they convert sets of numbers into a ratio. After practicing, they use the ratios and proportions to solve story problems. They also calculate map distances and discover map...

Students solve problems using estimation and exact calculations. In this algebra instructional activity, students use gum balls and thread to create hands on manipulatives to solve problems. They calculate the average of their total...

Students create a map to scale using technology. In this algebra lesson, students navigate through a shipwreck to perform rescues. They use he CEENBoT program to perform the different tasks.

Students investigate the use of multiplication and division of whole numbers to solve problems including equivalent ratios and rates.

Pupils complete a worksheet using M & M's to calculate percentages. They are given demonstrations by the teacher to know how to complete the activity.

Students investigate the concept of using box and whisker plots. They demonstrate how to use them to compute median, mode, and range. Students compare and contrast the complete and systematic processes use to solve problems. This is done...

Seventh graders explore the skill of finding the increase and decrease of a quantity. Calculating the increase and decrease is covered by a percent. The proporition for finding a percent is also part of the lesson.

Students find the percent of increase or percent of decrease. Through a teacher demonstration, they examine the methods of calculating percentages. Students solve real life problems.
