Discover how to solve systems of inequalities by graphing. An informative video shows pupils how to determine the solution set after graphing each inequality of a system. To finish, a worksheet gives them a chance to practice this skill.

Starting with questions about the tilt of the Earth and apparent motion of the sun, a worksheet provides instructions on how to figure the paths of the Sun on certain dates. Learners answer three more questions, complete with...

Investigate how rounding affects values. Individuals watch a video about how to find the highest and lowest possible numbers that result in a given value when rounded to a certain place value. They finish by completing a worksheet of...

A dimensional resource teaches viewers to recognize 2-D views of 3-D objects and how to match nets with their 3-D figures. Individuals draw different views of three-dimensional objects including views from the front, side...

Viewers learn how to apply proportional reasoning to find area of sectors and arc lengths with a video that starts off explaining how to find the areas of circle sectors and the lengths of arcs. Scholars then practice solving problems...

Upper graders use the properties of right angle trignonmetry to measure objects such as the school flagpole. They solve real world problems using these properties.

Students examine a sample budget and categorize the entries as a group. Then in small groups they convert budget category totals to percents and degrees to make a circle graph related to a sample budget.

What a wonderful resource! Learners create two-dimensional shapes according to the instructions stated, use the squares to make a triangular prism, a cube, and a pyramid, and identify features of plane shapes, among a myriad of other...

Have you ever tried to light ice on fire? With methane hydrate, you can do exactly that. The ice forms with methane inside so it looks like ice, but is able to burn. The lesson uses group research and a hands-on activity to help scholars...

Who knew that a possible answer to Earth's energy resource problems was lurking deep beneath the ocean's surface? Part four of a six-part series introduces Earth Science pupils to methane hydrate, a waste product of methanogens. After...

What's similar about congruent and similar polygons? Young mathematicians first measure the side lengths and angles of given figures. They use these measurements to determine relationships between side lengths and angles of congruent and...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Learners discover how to find missing sides and angles using trigonometry. Scholars first watch a video covering the Law of Sines and Cosines, as well as the area formula for a triangle. To test their knowledge, they complete a activity...

Students investigate how to read a topographical map and triangulate with just a map. They convert a compass measurement to a protractor measurement, reverse a bearing direction, and using a worksheet take a bearing of certain landmarks...

Students explore symmetry.  In this geometry and scientific inquiry instructional activity, students design paper airplanes with middle line symmetry, as well as right, obtuse, and acute angles.  Students measure the plane's...

In this latitude and longitude worksheet, students complete 4 activities to demonstrate understanding. Kids use a protractor to measure angles on a map of the earth. Students fill out a latitude and longitude chart after studying a map...

Students make a circle graph. In this graphing lesson, the teacher conducts a class survey, then demonstrates how to make a pie graph. When students are comfortable with the material, they use a worksheet to create their own graph.

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.

Put the better archer in a box. The performance task has pupils compare the performance of two archers using box-and-whisker plots. The resource includes sample responses that are useful in comparing individuals' work to others.

Designers in Prague are not diagonally challenged. The mini-assessment provides a complex pattern made from blocks. Individuals use the pattern to find the area and perimeter of the design. To find the perimeter, they use the Pythagorean...

After watching a video on making conversions, young mathematicians solve 16 math problems that involve making conversions of fractions to decimals and percents, decimals to fractions and percents, and percents to fractions and...

Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.

Which deal is best? Learners determine which of two companies has the best deal for a particular number of shirts. They begin by creating a table and equations containing each company's pricing structure....

Students participate in finding the slope of a sand pile and then other materials. In this geology lesson, students describe what happens to the piles of materials when they are poured through a funnel. Students measure the slope using a...
