In this third of a twelve-part series, the focus moves from using matrices to solving systems of equations with substitution and elimination, including more than two dimensions and variables in equations, and analyzing statistical data....

Students cut yarn into several different lengths and fold paper in half, using skills for measuring and fractions. Then they use unconventional items (yarn) as tools to create mirror-image art and experience first-hand the math idea of...

Take your drafting and design projects on the go with with this mobile computer-aided design program. Allowing users to view, edit, and share their work with others, this is a great resource for developing the technical drawing...

Students use the correct tool to measure distances. For this geometry lesson, students use an odometer and ruler correctly as they study maps. They describe how far way something is.

Young scholars explore measurement and estimation with non-standard units. In this measurement lesson, students discuss items that could be used to measure; they use tooth picks to measure specific items around the classroom, both...

Second graders estimate and measure various classroom objects using an apple as their tool for measuring, and record their measurement results on a data worksheet.

How do degrees relate to radians? The interactive allows pupils to manipulate the size of an angle in a unit circle to help see that relationship. Users determine the radian measure for given degree measures of angles, realizing the...

A six-question interactive tasks mathematicians to solve addition and subtraction problems using front-end estimation. Question types consist of multiple-choice and true or false. A set of wooden beams that can be measured using moveable...

Forget hours, divide the day into radians instead. Class members convert the angles in a pie chart of daily activities into radian measures. They add angle measures for multiple activities then determine a relationship between the radian...

Assist your class with each angle of geometry as they use exterior angles to form linear pairs with adjacent interior angles. They cover multiple vocabulary terms and work practice problems, complete with justifications, before...

With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.

What time is it when the arc length is pi? An interactive displays the measure of the angle created between the hour and minute hand of a clock. Pupils can set the clock to different hours and calculate the arc length based upon the radius.

How are arc lengths and radians related? An interactive resource demonstrates the relationship as pupils create arc lengths in a unit circle and compare them to the angle measurements. Questions ask individuals to build upon this...

Commutive and associative properties are the focus of a five-question interactive. Dealing with decimal multiplication and addition, mathematicians solve multiple-choice and true or false questions using a model that moves balloons along...

Five questions make up an interactive designed to boosts knowledge of area and volume of solid figures. Question types include multiple-choice, true or false, and fill-in-the-blank. A scale model changes measurement to provide a visual...

Tests mathematicians' knowledge of decimals, place value, and rounding with a five-question interactive. A tool with movable parts assists scholars in answering questions—multiple-choice and true or false.  A discussion question...

Young scholars create tasty faces. In this food lesson, students use rice cakes to make a funny face. Young scholars follow directions and use creativity for this activity. Students make a list of things they need from the grocery store...

Students investigate radioactivity as a tool for measuring geologic time and how geologists use this information to determine the absolute age of rocks or minerals.

Students practice measurement using real world objects. In this scavenger hunt for lengths lesson, students collaborate to measure with rulers, yardsticks, trundle wheels, and tape measures.  Students must estimate the length then...

Students become familiar with how to get information from the Internet. In this math and technology lesson plan, students measure objects on a measurement sheet found on a web site. They practice using a standard unit of measurement...

When measuring the circumference of a tree, does it matter how high you place the measuring tape? Most scholars have never considered this question, but scientists know that measurement techniques must be standardized. The 13th...

Students understand the concept of how to use different measurement tools for specific purposes. Students take pictures of various objects that can be measured using a digital camera and then making a power point presentation.

Is that a right triangle or a wrong triangle? Young mathematicians look at eleven different shapes and use a measuring tool of their choice to determine which triangles have right angles. Consider cutting out sets of the shapes to...

Can people really measure time just by using the sun? Scholars venture outside on a nice, sunny day to build sundials and learn how people measured time 600 years ago. The class builds two different sundials while gaining practice with...
