Sharon's Problem Solving

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 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 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.

This activity gives students the opportunity to create simplified expressions. They will use the distributive property to find the expression that fully describes a specific polygon. It can be used as a warm-up activity, formative assessment, or homework assignment. Topics and skills used in this activity.: Using the distributive propertyIdentifying common attributes of a polygonSimplifying algebraic expressions
