This book is a "flexed" version of CK-12's Basic Geometry that aligns with College Access Geometry and contains embedded literacy supports. It covers the essentials of geometry for the high school student.

CK-12 Foundation's Geometry FlexBook is a clear presentation of the essentials of geometry for the high school student. Topics include: Proof, Congruent Triangles, Quadrilaterals, Similarity, Perimeter & Area, Volume, and Transformations.

In this lesson, students complete several activities that involve coordinates and graph paper given the following invitation to learn: "Suppose you are having a birthday party and a friend you have invited has asked you for directions from the school to your house. You tell them it is five blocks away. Is this enough information for them to find your house?"

Simple machines are devices with few or no moving parts that make work easier, and which people have used to provide mechanical advantage for thousands of years. Students learn about the wedge, wheel and axle, lever, inclined plane, screw and pulley in the context of the construction of a pyramid, gaining insights into tools that have been used since ancient times and are still important today. Through numerous hands-on activities, students imagine themselves as ancient engineers building a pyramid. Student teams evaluate and select a construction site, design a pyramid, perform materials calculations, test a variety of cutting wedges on different materials, design a small-scale cart/lever transport system to convey building materials, experiment with the angle of inclination and pull force on an inclined plane, see how a pulley can change the direction of force, and learn the differences between fixed, movable and combined pulleys. While learning the steps of the engineering design process, students practice teamwork, creativity and problem solving.

A structured geometry program teacher edition of daily lesson plans and teacher supports to accompany the College Access Reader: Geometry student edition.

This activity allows the user to plot points on the coordinate plane and to read the coordinates of a point plotted by the computer.

CK-12 Geometry Teacher's Edition covers tips, common errors, enrichment, differentiated instruction and problem solving for teaching CK-12 Geometry Student Edition. The solution and assessment guides are available upon request.

The purpose of this lesson is to teach students about the three dimensional Cartesian coordinate system. It is important for structural engineers to be confident graphing in 3D in order to be able to describe locations in space to fellow engineers.

After reading the story, The Silly Story of Goldilocks and the Three Squares, students identify and describe shapes in a variety of orientations.

In this lesson, students develop spatial sense by composing shapes to match their teacher's representation.

Having spatial sense means having a feel for the geometric aspects in the environment and how the different shapes can be combined to form different figures. Students do not "grow" this spatial reasoning without having rich experiences that involve shapes and spatial relationships.

This packet contains exit tickets for the Kindergarten, Cluster 4 geometry standards. Exit tickets are written responses to questions posed at the end of a lesson. They are brief assessments which allow the teacher to determine student understanding of the concepts and skills taught that day. At the Kindergarten level, a blank copy of the exit ticket should be displayed on the board and read aloud to students. As teacher reads, students work independently on their own copy of the exit ticket.

In this task, students identify shapes, describe attributes of shapes, and compare a two-dimensional and three-dimensional shape. This task may be used for instructional or assessment purposes.

The goal of this lesson is for students to understand that plane figures are different from solid figures. Students will identify and locate the face of a solid figure that matches a plane figure, such as the face of a cube is a square, the base of a triangular based pyramid is a triangle.

In this lesson, students will create and name given shapes. They will use precise mathematical vocabulary describe shapes to partner with enough details for the partner to recreate it accurately.

In this lesson, students create a "train" (or row) of shapes. Each shape in the row must have one attribute in common with the shapes on either side.

Students are asked to draw a set of two-dimensional shapes, and build three-dimensional shapes from clay. This task may be used for instructional or assessment purposes.
