Standard #: MAFS.4.MD.3.5 (Archived Standard)

Students are given two angles with the same angle measure but with sides of different lengths and asked to explain which component of an angle determines its measure.

Students are asked determine angle measures based on how many one-degree turns are made.

Students are asked to analyze two angles and explain how their measures are determined.

Students are asked to circle figures that show angles from a set of figures and then describe the defining attributes of angles.

This set of geometry challenges focuses on creating circles and calculating area/circumference as students problem solve and think as they learn to code using block coding software.  Student will need to use their knowledge of the attributes of polygons and mathematical principals of geometry to accomplish the given challenges. The challenges start out fairly simple and move to more complex situations in which students can explore at their own pace or work as a team. Computer Science standards are seamlessly intertwined with the math standards while providing “Step it up!” and “Jump it up!” opportunities to increase rigor

This lesson will provide students with the opportunity to see angles all around them. Students will be able to see how and where geometry exist in the real world.  Please note that this lesson focuses on identifying acute, obtuse, right, straight and reflex angles.

In this lesson students will make snowflakes, promoting creativity and self-expression, and use them to identify geometric terms. It also gives them an opportunity to follow a sequenced set of instructions for a given outcome.

This is a lesson that introduces right, acute, obtuse, reflex, straight angles in a fun and challenging way.

In this lesson, students work to identify points, lines, line segments, rays, angles and perpendicular and parallel lines. Students create webs of yarn and analyze the web for geometric properties listed above. A teacher can select which vocabulary terms are appropriate for the class.

In this lesson students will be introduced to the protractor and benchmark angles, practice reading angles properly, make estimates on angle degrees, measure angles precisely, and participate in a small group activity using their new skills.

Students will use small paper airplanes to model rotations required to turn onto a runway. Students will rotate planes 45, 90, 180, 270, and 360 degrees. Students will identify and describe the results of rotations using benchmark angles.

Discover what an angle is by helping to program a robot through an obstacle course in this interactive tutorial.

The purpose of this task is to give students a problem involving an unknown quantity that has a clear visual representation. Students must understand that the four interior angles of a rectangle are all right angles and that right angles have a measure of 90° and that angle measure is additive.

in this tutorial, students will learn about central angles and arcs of a circle.

This Khan Academy tutorial video identifies acute, right, and obtuse angles and justifies each identification. 

This Khan Academy tutorial video demonstrates the relationship between the measurement of an angle and the arc of a circle.

This Khan Academy tutorial video presents how an angle is formed and labeled.
