Fifth graders use tan to solve problems involving right-angled triangles. They solve equations of the form tan(8) =a, for a between 180 degrees and 360 degrees. They state the value of tan (8) in special cases.

Learners solve problems with percents, decimals and fractions. In this algebra lesson, students convert between fractions, percents and decimals. They estimate their answers and calculate their answer.

Fifth graders discover in hands-on activities the relationships between the measures. They work in groups to create conversion tables using familiar measuring tools. Students solve problems requiring conversions.

All 20 of the problems on the learning exercise involve the computation of cubic volume or density. As long as your young scientists can apply the appropriate mathematical formulas, they will succeed in solving these problems. They are...

Students explore the long distances and timescales involved in space travel. They track the progress of the New Horizons spacecraft and access the New Horizons website to discover the distance of the spacecraft from the Sun, and then...

Second graders create a thermometer.  In this Celsius or Fahrenheit instructional activity, 2nd graders create an individual thermometer to use for measuring the temperature.  Students convert the outside temperature. 

In this factoring worksheet, students express numbers as a 3 significant digit number in scientific notation. Students practice converting mass, volume, and length. This worksheet has 3 problems to solve.

In this measurements worksheet, students review how metric conversions work and the prefixes associated with the conversions. Then students complete 27 problems, 1 short answer, 14 matching, and 7 fill in the blank questions.

Students determine how to convert measurement. In this English Measurement lesson, students discover interesting facts about the history of measurement. Students study formulas and practice using them.

In this exploring cities from space instructional activity, students use a satellite image from the QuickBird Satellite to determine the image scale. They use the image scale to calculate the length of the Bellagio Hotel in Las Vegas,...

Fourth graders visit a real pond. They mark the pond's curvilinear perimeter using string. They measure the string to find the actual perimeter of the pond.

In this water on Mars worksheet, students use a diagram to answer four questions about the structures in the image. They find the dimensions of the image, the width of the streams half-way down their flow channels, the smallest feature...

Students investigate the growth rate of a man named Bob Wadlow.  In this growth rate of a man lesson, students determine if the growth rate of this particular man was normal or abnormal.  Students bring in data of their height...

In this Mars Rover Landing worksheet, students are given an image of Mars near the Bonneville Crater. Students determine the image scale in the diagram and use it to find the diameter of the Bonneville Crater, the width of the Rover's...

In this geometry activity, 10th graders build a swimming pool using math to calculate all of the different dimensions. The pool is rectangular in shape and is measured in yards or meters. Students must convert to different units to solve...

Young scholars investigate the Metric System. They discuss the history of the Metric System, convert various units of measurement into the Metric System, and solve problems on a spreadsheet.

Students explore weight. In this math lesson, students predict which item weighs more and discuss how they arrived at their decision. Students weigh several items to determine which weighs more.

Students construct using Cabri software. In this geometry lesson, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the desired measurements.

Students build and apply concepts of geometry. In this geometry lesson plan, students create a building using proportions and scale drawings. They use Cabri technology to create a virtual drawing first.

Students convert angle measures between degrees and radians. They are given a copy of the task sheet with a graphic to help describe the situation. Pupils review the angle and arc relationship in a circle related to length of the...

Students build knowledge about the number relationships between decimals and percents as it relates to converting decimals into percents. In this decimal and percent lesson, students recognize equivalent forms of fractions,...

This unit covers the basic trigonometry including understanding radians, how to convert between radians and degrees, the area of a circle subtended by an angle, basic properties and graphs of sine, cosine, tangent, and solving...

In this metrics activity, students read information about the metric system. Students review the concepts of prefixes, conversion ratios, and the decimal system. This activity has 17 matching, 31 fill in the blank, and 8 word problems.

In this SI prefixes and mass worksheet, students are given measurements of mass and they covert to the given measurement by moving the decimal the proper number of places to the left or right.
