Lesson Planet: Curated OER

#### Geometry Unit 11: Circles

The five resources in the Geometry Unit 11: Circles Unit Module are designed for the flipped classroom. Pupils watch videos that show how to apply concepts about circles, tangents, congruent chords and arcs, and intercepting arcs....

Lesson Planet: Curated OER

#### Exploring Space Through Math: Geometry

Young mathematicians use their knowledge of geometry and precalculus to study the movement of the robotic arm on the International Space Station (ISS) and the flight pattern of NASA’s C-9 jet. In addition, they use spherical coordinates...

Lesson Planet: Curated OER

#### Exploring Space Through Math: Geometry

The Exploring Space Through Math series offers six geometry lessons that use NASA resources to teach learners how to use the mathematics of deductive and spatial reasoning. They use geometry to compare the dimensions of the NBL pool, the...

Lesson Planet: Curated OER

#### Exploring Space Through Math: Algebra II

The three lessons in the Algebra II series Exploring Space Through Math expand learners’ knowledge of algebraic thinking and symbolic reasoning and encourage them to connect algebra and geometry. Activities include calculating the number...

Lesson Planet: Curated OER

#### Circles

Don't circle around the topic, but get right to the center with tons of practice regarding circles in geometry. The note-incorporated activity provides guided practice through many topics such as central angles, inscribed polygons and...

Lesson Planet: Curated OER

#### Task: Grain Storage

Farming is full of mathematics, and it provides numerous real-world examples for young mathematicians to study. Here, we look at a cylinder-shaped storage silo that has one flat side. Given certain dimensions, students need to determine...

Lesson Planet: Curated OER

#### Secants and Tangents

Put the vertex in, put the vertex out. Pupils explore theorems about the relationships of lengths of segments and angles of line segments that intersect inside or outside the circle. Learners use the theorems to solve problems involving...

Lesson Planet: Curated OER

#### Intercepted Arcs

Intercept the class's learning on circles. Pupils learn the relationship between intercepted arcs and inscribed angles. The scholars use that information to find the relationship of angles in an inscribed quadrilateral and an angle...

Lesson Planet: Curated OER

#### Chords and Arcs

Congruence breeds congruence. Pupils learn three more circle theorems dealing with congruent chords and arcs. Learners use the theorems to find the measures of chords and arcs in circles by applying previously learned concepts in the...

Lesson Planet: Curated OER

#### Tangents to Circles

Touch a circle once. Individuals watch a video and learn two theorems related to tangents and circles. The pupils then apply the theorems to find missing angle measures and lengths in figures. At the end, they practice their skills on...

Lesson Planet: Curated OER

#### Where Should We Sit?

Where's the best seat in the house? Given a diagram of a movie theater, pupils determine the best seats based on the viewing angle. They use inscribed angles to justify their choices.

Lesson Planet: Curated OER

#### Shooting Arrows through a Hoop

The slope makes a difference. Given an equation of a circle and point, scholars determine the relationship of the slope of a line through the point and the number of intersections with the circle. After graphing the relationship, pupils...

Lesson Planet: Curated OER

#### Outward Bound

Just how far can I see? The short assessment question uses the Pythagorean Theorem to find the distance to the horizon from a given altitude. Scholars use the relationship of a tangent segment and the radius of a circle to find the...

Lesson Planet: Curated OER

#### Angles in the Same Segment – Proof

If angles intercept the same arc, the angles must be the same size. The quick video talks through the proof of showing the reason two inscribed angles that intersect the same arc have the same measurement. Pupils then create their own...

Lesson Planet: Curated OER

#### Orthogonal Circles

Here's some very interesting circles for your very interested pupils. A performance task requires scholars to sketch a pair of orthogonal circles so the centers are the endpoints of one side of a triangle. They draw an additional circle...

Lesson Planet: Curated OER

#### Circle Theorems (Examples)

No math lesson would be complete without examples. A short video works through examples highlighting circle theorems. This includes problems where individuals must take multiple theorems into account to determine the solution.

Lesson Planet: Curated OER

#### Module 5: Circles A Geometric Perspective

Circles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...

Lesson Planet: Curated OER

#### Alternate Segment Theorem – Proof

Scholars observe a video explaining the alternate segment theorem proof. Then, they apply the theorem to additional practice problems from the text and complete a worksheet.

Lesson Planet: Curated OER

#### Angles at the Centre and Circumference – Proof

Scholars ponder the proof relating the center angle and circumference using a demonstrative video. Additional worksheets and textbook practice helps them demonstrate their intellect.

Lesson Planet: Curated OER

#### Spinning an Old Record

Take a trip back in time to examine angular velocity. Using the revolutions per minute, learners calculate the speed of a point on a 33 record. They compare the speed of a point on the edge of the record to the speed of a point closer to...

Lesson Planet: Curated OER

#### Bicycle Chain

Model a bicycle chain with circles and tangent lines. Given the dimensions of the sprocket wheels, young scholars calculate the length of the chain that surrounds them. A second task has learners write a function for the length of a...

Lesson Planet: Curated OER

#### Module 1: Transformations and Symmetry

No need to change anything about the resource. The first of eight modules in the MVP Geometry unit focuses on transformations in the coordinate plane. It connects translations, rotations, and reflections to congruence, symmetry, and...

Lesson Planet: Curated OER

#### Always, Sometimes, Never

Do your learners always, sometimes, or never remember the properties of the segments in triangles? Get that number closer to always with a creative lesson analyzing all four segments. Scholars consider a statement about one of the...

Lesson Planet: Curated OER

#### Suitcase Circle

Analyze patterns in a circular arrangement. After using a geometric construction to complete a circle, learners use proportional reasoning to make predictions. By determining the length of an arc built from suitcases, they estimate the...
