It's probably a good idea to use the unit. Young mathematicians learn about conditional probability using Venn diagrams, tree diagrams, and two-way tables. They also take into consideration independence and the addition rules.

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Consider the relationship between side length and area as an input-output function. Scholars create input-output tables for the area of squares to determine an equation in the first installment of a three-part unit. Ditto for the area of...

Wrap up the unit in one final design. Pairs use their knowledge of aviation to design new flying machines and record how their designs take into consideration the forces that act upon airplanes. The pupils determine whether their designs...

Help your learners examine triangles. Pupils explore the different sizes and measurements of triangles. They discover triangles can be isosceles or scalene, and examine the attributes of triangles. Here is the website where you can...

Math scholars study conics and how they are used today. In this mathematical lesson, pupils construct and slice cones after viewing a demonstration. 

Middle and high schoolers research the life of Pythagoras and the Pythagorean theorem. They write a short biography of Pythagoras and learn to apply the theorem in their study of right triangles.

In the activity on this webpage, learners use interactive graphing technology to investigate transformations of graphs. In the first part of the task, they look at the graph of a quadratic function with coordinates of a few points...

What does similarity have to do with the Pythagorean Theorem? The activity steps through the proof of the Pythagorean Theorem by using similar triangles. Next, the teacher leads a discussion of the proof and follows it by an animated...

Prove the Pythagorean Theorem using multiple informal proofs. Scholars first develop an understanding of the origins of the Pythagorean Theorem through proofs. They round out the lesson by using the theorem to find missing side lengths...

Is it a right triangle or not? Introduce scholars to the converse of the Pythagorean Theorem with a lesson that also provides a proof by contradiction of the converse. Pupils use the converse to determine whether triangles with given...

Examine the application of the Pythagorean Theorem in problem-solving questions. Pupils apply the theorem to find lengths when given different scenarios. They finish the 17th installment in an 18-part series by applying the theorem...

In this algebra worksheet, 10th graders apply inductive reasoning as they figure out the next number in the sequence or pattern. There are 53 problems.

In this volume and surface area worksheet, students find the volume and surface area of different solid figures. Students complete 8 problems.

In this circumference and area worksheet, students find each for a set of 12 given circles; either diameter or radius are given. A website reference for additional resources and answers are provided.

In this circumference and area of circles worksheet, learners find each to 1 decimal place of 12 given circles. A website reference for additional resources and answer key are given.

Have your class learn about buoyancy using this simple lesson plan. First, they bring in condiment packets and see what happens when they place it in a glass of water. Then, they use one of the packets to illustrate the concept of a...

In this Algebra II worksheet, 11th graders solve problems involving the laws of exponents, including fractional exponents, solve radical equations, and graph radical functions.  The ten page worksheet contains fifty-seven...

Young scholars explore patterns and sequences. Given an example of each, they discuss their observations. In groups, students participate in an "Around the World" activity where they rotate to different stations in the classroom to...

Seventh graders examine the process of constructing a site plan map at archaeological sites. They discuss the process of mapping techniques and calculation of percentages, create a plan site map of a cellar at Jamestown, and calculate...

Young scholars discover that four special segments have a common intersection point. They identify the position of the intersection point in triangles. They produce conjectures about areas of the divided triangles.

Test your knowledge of coordinate geometry by taking this twenty question multiple-choice practice test. Use a graphing calculator to help with any graphing problems and check your answers at any given time throughout the test.

Half-length practice test for the tenth grade Ohio Graduation Test (OGT). The test includes 16 multiple-choice and 3 open-response questions dealing with topics such as number sense, algebra, geometry, data analysis, and measurement. A...

Full-length practice test for the tenth grade Ohio Graduation Test (OGT). The test includes 32 multiple-choice and 6 open-response questions dealing with topics such as number sense, algebra, geometry, data analysis, and measurement. A...
