Students measure using tools they have made. In this algebra lesson, students measure the height and distance using non-traditional measuring methods. They apply their findings to algebra and trigonometry properties of measurements.

Students explore Earth science by participating in a weather identification activity. In this scientific instrument lesson plan, students identify several weather related tools such as the weather vane, thermometer and rain gauge....

First graders practice measuring. In this measuring lesson, 1st graders read the story How Big Is a Foot? by Rolf Myller. They measure a partner using standard (ruler) and nonstandard (feet) units.

Third graders explore measurement. In this estimation and measurement lesson, 3rd graders examine visual examples using standard units to measure length. Students also practice solving problems that their instructors model.

Learners learn how tools help us accomplish things. In this tool discovery lesson, students review the function of tools. They then make a class chart and categorize different types of tools found in the classroom. Finally, they create a...

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.  

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Students create metallic Bas-relief scultures using basic art supplies and the technique of "tooling" in this Art lesson with croos-curricular connections in Social Studies and Math. A scoring rubric is included for assessment and...

Groups of students rotate through five classroom stations to estimate, measure, and record volume, length, weight, mass, and area using both customary and metric measure. They evaluate their data to determine how close their estimates...

Students measure angles using a plane table kit. In this geometry lesson, students use trigonometric identities to find the values of the length of a football field.

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging students to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

 In this geometry instructional activity, learners read The Greedy Triangle and use geoboards to construct geometric shapes. They identify the number of sides and angles each shape has.

Upper graders solve ten multiple choice problems about angles and measuring angles.

Use a clock face to develop angles representing standard position angles. The interactive allows pupils to create angles using the hands of a clock. Scholars discover that there is a difference in the angle formed using a clock face and...

Young geometers investigate and apply properties of quadrilaterals.  After a review and discussion of key terms, learners use a computer applet to explore four-sided figures and classify them according to their attributes. The...

Serve up a slice of math for Pi Day! A combination of fun, hands-on lessons and helpful worksheets encourage learners to practice finding the radius, diameter, and circumference of different circles.

A five-question interactive test scholars' knowledge of adding and subtracting decimals. A tool aids in problem-solving with movable parts that reveal addends and sums. Question types include one discussion, fill and in the blank, and...

Blend art, adolescent snacking habits, and math to create new cereal boxes. Secondary learners review scale drawings. They use this information to construct cereal boxes to scale and will compare their creation to the original product to...

Observe the change in the trigonometric ratios as angles vary. An interactive provides the values of trigonometric ratios for both acute angles in a right triangle. Pupils create a right triangle to match given criteria and find the...

When is the trigonometric value of a negative angle the same as the positive angle? Pupils compare the values of trigonometric functions for different angles and their negatives. The interactive resource provides a visual display to make...

Acute or obtuse? Seems right to me! As scholars explore the simulation, they investigate angle measures. Questions ask them to classify the angles using correct naming conventions.

There's more to a quilt than just a pretty pattern—there's geometry! Explore angle classification using an artistic approach to show your class that quilt designs are really just intricate geometric patterns. Here, scholars create a...

Find the perfect amount of water for lemonade. Scholars solve the famous problem of measuring four liters of water using a three-liter container and a five-liter container. An interactive allows users to see each step of the solution.

Hyperbolas—practice thinking outside of the box. Pupils alter the end behavior box to create various graphs of hyperbolas. They determine formulas to find the distance from the origin to the foci. Using that information, scholars...
