The Tangram Linear Equations activity asks students to use coordinates, point-slope form, and slope-intercept form to find the equations of line segments. Students are also asked to identify parallel and perpendicular line segments based on equations. Topics addressed:Coordinate pointsPoint-slope formSlope-intercept formParallel linesPerpendicular linesA rubric and answer key are provided. Tangram Linear Equations can be used as a formative assessment or math center activity.

The Circle Property Scavenger Hunt asks students to slide the correct definition and image to each topic. Self-correcting slides are included. Topics included: TangentSecantChordSemicircleInscribed angleCentral angleCross SectionSectorArc This activity includes a ten question, self-grading, quiz which can be used as a formative assessment. I found this activity to be a good way to engage reluctant learners.

The Circle Problems Collection contains 5 challenging problems involving circles and their properties. Rubrics and answer keys are included. The collection can be used as a packet, formative assessment, review, or problem solving exercise. Topics included: CircumferenceAreaDiameterRadiusSquare rootsCircumscribed circlesInscribed circles

The Derive and Use the Sphere Formulas slides give students the opportunity to "build" the sphere formulas for surface area and volume. Students are asked to investigate the ratios of spheres to cylinders. Problem sets are self-correcting and include challenge problems. Topics included: Volume of sphereVolume of ConeVolume of cylinderSurface area of sphereSurface area of cylinderLateral surface area of cylinderThe slides are appropriate for a math center activity, homework assignment, or review.

The slides have 6 challenging volume of a sphere problems that are self-correcting. When students click on their choice they are brought to a slide that tells them that their answer is correct or to the process and correction allowing for immediate feedback. An additional problem with the same multiple choice format asks students to calculate the circumference of the Moon's orbit. The problems include detailed images that provide students with the information that is needed to calculate the vol

The Parallel and Perpendicular Line Puzzle, Matching and Tangram Activities provide students with two opportunities for practice. The puzzle asks students to follow a path of word problems to solve. The matching activity requires students to match the required equation. In the Tangram Activities, students must write and identify equations for parallel and perpendicular lines from a graph. All activities can be solved independently or cooperatively. They can be used as a formative assessment, ac

The Linear Topics Bundle contains an activity that asks students to take a closer look at the multiplication chart to find equations. Students are asked to graph, find patterns given the equation, and complete kinesthetic activities. There are challenge problems that ask students to maximize a solution, find direct variation equations, equations of parallel and perpendicular lines and in standard form. Students can also practice writing algebraic expressions and solving for avariable. Topics in

The Square Pyramid Roof Problem with step-by step solutions asks students to find the volume between a roof and the attic which are represented by a square pyramid and a cube respectively. Either Special Right Triangles or the Pythagorean Theorem can be used to solve this problem. An assessment and answer key are also included.

The Direct Variation Problems and Activities document asks students to investigate, calculate, plot, interpret, and actively engage with the concept. The rubrics can be used by the student and/or teacher. The document can be completed electronically using TpT Easel. The Direct Variation: Decode the Message Puzzle asks students to identify equations, graphs, and patterns that are direct variations. The activity can be used as a formative assessment. Topics Included: Direct Variation EquationsGrap

Students are asked to match the correct image with the name of the polygon. The activity is a good formative assessment and is available with TpT Easel. The activity also asks students to correctly name the additional images of the polygons that do not have a match. The answer key is included. Topics included: Parallel Lines Perpendicular Lines Octagon Hexagon Heptagon Pentagon Parallelogram Rhombus Trapezoid Equilateral Triangle Scalene Triangle Isosceles Triangle The activity is an excellent f

The circles bundle includes a circle properties and definitions activity made for use with Google Slides, circle word problems with rubrics and answer keys. There is also a circle property scavenger hunt that asks students to match a definition and image for each term. There is a pdf version which is included as a bonus. This version asks students to find an image, or make a sketch of an image. There are two Google slides for sphere activities that have self-correcting slides, guided investigati

The matching activity asks students to match the definition or formula with the geometry vocabulary word. The slides are self-correcting. Topics addressed: Area of a circle Circumference of a circle Radius Diameter Inscribed circle Circumscribed circle There is a ten question, self-grading quiz that is included which can be used as a formative assessment.

The Circle Property Scavenger Hunt asks students to take or capture photos (with attributes) of defined circle properties . Students have the option to sketch images. There is also a photo bank that can be cut and pasted into the table. The pdf version has 8 pages. The activity is formatted for use with TpT Easel with an answer key and 5 pages.
