Students explore the concept of the corner problem. In this corner problem instructional activity, students use the TI-NSpire to determine the maximum length a rod can be and still pass horizontally around a corner. Students use similar...

Students identify the ratios of trig functions. For this trigonometry lesson, students construct triangles and use it to derive the values of sine, cosine and tangent. They use Cabri software to create the visual of the identities.

Learners explore the application of Hinge Theorem. In this geometry activity, students write inequalities, given two sides of a triangle. They solve problems with triangular inequalities using the proper theorem.

Students perform reflections and translations of polygons. In this geometry lesson, students perform reflection in two parallel lines. They use Cabri to observe the transformation and rotations of each shape.

Students compare and order numbers. In this geometry instructional activity, students write equations for inequalities. They differentiate and apply concepts of triangular properties to solve problems.

In this powers worksheet, students multiply and divide expressions containing variables and exponents. They convert numbers from scientific notation to standard notation. This two-page worksheet contains 5 multi-step problems.

Learners examine two plants that make skateboards. They practice converting fractions to percents in real life applications.

Students solve problems using the law of sines.  In this sines lesson, students work in groups and individually to solve problems using the law of sines.  They identify real life problems that require the use of the law of...

A hands-on lesson created students use beans as manipulatives to solve addition number sentences. Requires the book, Mission Addition by Loreen Leedy.

Fourth graders investigate the effects of temperature on Native American lifestyle and culture. In small groups they conduct research on cultural practices showing a connection to the climate and create a poster displaying their...

Students listen as the teacher tells the story of Sisyphus rolling the stone up the mountain. Students prepare two batches of jello, one with fresh pineapple, and one with canned pineapple. While the jello is setting, students work on...

Seventh graders develop an examineing of absolute value through real world situations. They develop an examineing of when absolute value can be used in a given situation.

Sixth graders identify and draw two-dimensional representations of a three-dimensional object. Students investigate the views of an object and determine that three views are required (front, one side and the top). Students use these...

The investigation of exponential equation in the context of increasing college tuition costs is explored through this lessib.  Students write exponential equations based on the percent of change of college tuition and use their...

Students accurately measure several common objects for thickness using micrometer calipers. They work individually to analyze whether given objects would meet the correct specifications required for a particular manufactured product.

Fourth graders identify and label different types of polygons in real life situations. Using a digital camera, they take pictures of polygons on the school grounds, tally the number of shapes found, and answer discussion questions.
