Middle schoolers build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by...

In this indirect Euclidean proof worksheet, learners write statements supporting the reasons for a given proof. This one-page worksheet contains ten problems.

In this math vocabulary activity, students complete 15 multiple choice problems, choosing the correct definition for a set of math terms. A reference web site is included for additional activities. 

In this math vocabulary worksheet, students complete multiple choice problems where they match the correct math vocabulary word to its definition. Students complete 15 questions.

Learners explore different types of quadrilaterals. Students define the terminology used with quadrilaterals. They create particular quadrilaterals based on specific characteristics of the quadrilaterals using an online tool.

Fourth graders build an explorer vehicle which they program through an obstacle course to enter the tomb or temple to discover artifacts.

Students use their understanding of 3D on 2D to make a representation of a 4D form on paper.

In this rounding learning exercise, students solve 40 problems in which whole numbers are rounded to the nearest 10. 100 or 1000. Students also round to the nearest dollar.

Fifth graders work with polygons.

Students explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Students identify different geometric shapes in the...

Fourth graders investigate regular polygons. In this regular polygon lesson, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.

This study guide on angles and transversals covers key terms, angle types formed by transversals, postulates and theorems about transversals, and how to prove if lines are parallel or perpendicular. It is available for download with free...

Explore lines and angles, and the relationship between the two.

Angles, parallel lines, and transversals are explained through examples and a video lesson. [1:01]

Explains angles and parallel lines through examples and a video lesson.

Explains the basic concept of intersecting lines and angles with step-by-step instructions and methods for solving specific problems on your own relating to this topic.

Explains the terms and symbols used to discuss line angles, what an angle is, and the types of angles. Includes short video lesson demonstrating how to use a protractor to measure an angle. [0:57]

2 OF 2 FOR ADDITIONAL TOPICS IN MATH. Students will use the coordinate plane and equations of lines and circles to describe figures; create the equation of a circle given the figure or use the structure of a given equation to determine a...

A list of geometry definitions and a matching activity.

A comprehensive guide for learning all about angles with definitions, examples, and practice questions.

This fourth-grade geometry lesson teaches the definitions for a line, ray, angle, acute angle, right angle, and obtuse angle. We also study how the size of the angle is ONLY determined by how much it has "opened" as compared to the whole...

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to find angles on and inside a circle created by chords and tangent lines.

[Free Registration/Login may be required to access all resource tools.] Use same side interior angles to determine supplementary angles and the presence of parallel lines.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students about corresponding angles, and how to use them to determine whether or not lines are parallel. Students examine guided notes, review...
