This investigation uses Cabri Jr. and a cleaver rotation of a triangle to "prove" that the angles in a triangle add up to 180. This could be used to reinforce triangles and paralled lines as well as introduce the concept of rotating an object.
Find out how angles and symmetry come into play in the game of pool in this video adapted from Annenberg Learner’s Learning Math: Measurement.
In this activity, students will investigate properties of angles and arcs formed when chords, secants, and tangents intersect and intercept arcs in a circle. They discover several important theorems concerning circles and arc sizes. They make use of the Central Angle theorem, which ensures that the measure of a central angle of a circle is equal to the measure of its intercepted arc.
Looks at parallel lines and intersecting lines (transversals), and the angles they form. [7:08]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
Students are introduced to the classification of animals and animal interactions. Students also learn why engineers need to know about animals and how they use that knowledge to design technologies that help other animals and/or humans. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

In this problem students are comparing a very small quantity with a very large quantity using the metric system. The metric system is especially convenient when comparing measurements using scientific notations since different units within the system are related by powers of ten.
Students will read and observer ants to discover how ants are the same and different than people.
This task requires students to work with very large and small values expressed both in scientific notation and in decimal notation (standard form). In addition, students need to convert units of mass.
Create customized decimal division worksheets. Choose from single-digit divisors into three-digit dividends up to three-digit divisors into five-digit dividends. The size of problem set can be selected, as well as whether the format will be standard or horizontal. An answer key can also be generated.
Explore how relationships such as distance and time, velocity and time, etc. can be expressed with function notation. Assess learning with a quiz. [1:52]
This video lesson provides a real-world application of function notation. Students can check their understanding with an assessment. [3:11]
Explore how to write function notation using real-world examples. Assess learning with a quiz. [2:58]
This short video and interactive assessment activity is designed to teach fifth graders about adding and subtracting lengths (metric units).
