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...

By using circles that they cut out and label themselves, learners literally "get a grip" on the angles they identify: supplementary, complementary, and vertical. They solve missing measurements based on properties of supplementary,...

After watching a brief video on addition and subtraction, young mathematicians are put to the test. Including 12 problems, individuals solve word problems to find the least number, total amount, and difference of numbers. 

Learners read a variety of word problems and find the mode, median, range, and mode from a given set of data. If calculators are not desirable, provide the class with notebook paper to work out the equations. 

Explore how to deal with fractional and negative exponents. Scholars watch a video reviewing fractional, zero, and negative exponents. After the video, they test their skills by completing a worksheet covering the concepts.

Students explore the concept of triangle inequalities.  In this triangle inequality lesson plan, students cut spaghetti noodles into given lengths.  Students use the noodles to complete a worksheet about triangle...

Young scholars find the altitude of the Sun at 10 A.M., at solar noon, and at 2 P.M. by measuring the height of the gnomon and the length of the shadow at each time. They record the measurements in their notebooks for later conversion.

Explore plants and flowers with this lesson. Learners talk about plants, conduct an experiment with suflowers, and track a plants growth. This is a motivating way to present this concept.

Here is a good lesson which invites learners to practice measurement using standard and nonstandard measuring tools. In this measurement lesson, learners work with length, width, height, and area. They use standard and nonstandard...

Second graders investigate how to slow the spread of germs from coughing and sneezing. In this illness prevention lesson, 2nd graders talk about why people cough and sneeze before telling about ways to prevent the spread of germs. They...

Students measure and calculate the angle of the sun. They compare the leaf types on the north and south to compare the effects of the sun on the type of vegetation. They complete the activities inside the classroom or on a trip to a...

Young scholars explore how to select among choices of variables and analyze the cost-benefit ratio of their short and long term planning in a team activity as they consider the planning and operation of a ski slope.

After being introduced to the basic trigonometry functions, students calculate the height of school landmarks. They experiment with different angles to find the correct height.

In this geometry worksheet, young mathematicians divide a parallelogram into four, by choosing points along a diagonal.  Students calculate the area of each parallelogram and look for any patterns that may emerge.  The one-page...

Students bisect angles and segments using a mira. They measure the original angles and segments and the angles and segments formed by bisecting to better see the relationship between them.

Students identify the six trigonometric ratios and properties. In this trig activity, students define basic trig functions as it relates to solving right triangles. They identify the equation for sine as o/h and cosine as a/h and tangent...

In this pie graph worksheet, students draw a pie graph for the zookeeper with the data he collected, choose a different color for each animal species and make a key to the graph.

Middle schoolers identify angles.  In this angles that pair lesson, students identify adjacent, vertical, complementary, and supplementary angles.  They use straws, pretzel sticks to demonstrate given types of angles. 

Eighth graders find missing angles of triangles, quadrilaterals and angles formed by parallel lines cut by a transversal. They use area formulas to find the area of a figure; find the complement and supplement of a given angle; and know...

For this triangulation worksheet, students solve and complete 11 steps of an experiment to determine the distance to a far away object using triangulation and trigonometry. First, they select a far away object and create a baseline far...

In this Aurora Borealis worksheet, students read about how early scientists used triangulation to measure the height of the Aurora Borealis. Students solve 3 problems using triangulation.

Students collect data to create different types of graphs-line, pie, and bar graphs. They use StarOffice 6.0 to create graphs.

Young scholars determine that two figures are similar or congruent by investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions, postulates, and...

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...
