Segment Addition Postulate Exploration! Geometry practice for grades 8-12. Promote student analytical thinking through an inductive approach to the segment addition postulate! Segment Addition Postulate Exploration is a great introduction to the segment addition postulate and can help in scaffolding this concept for students who need concrete, hands-on examples. Each student will take one piece of uncooked spaghetti and will follow the instructions on the activity sheet with a ruler and penc

Geometric Mean in Right Triangles is for grades 8-12 Many students struggle with finding the geometric mean in a right triangle. They struggle with seeing the relationships between the similar right triangles formed by the altitude and the largest right triangle. These manipulatives allow students to not only see how the right triangles are really similar triangles, but they also help students to solve using the Geometric Mean. Included are: *Printable double-sided manipulatives (so students

Everything Angles Bingo is an activity for grades 5-12. Students practice identifying different angles and angle pair relationships in parallel lines intersected by a transversal line by playing bingo. This activity is excellent for reinforcing the vocabulary through auditory, visual, and game based learning. After the game, the bingo board can be used as a graphic organizer! How the game works: The teacher pulls a strip with the name of the type of angle or angle pair written on it and the

Triangle Inequality Theorem Investigation! Geometry practice for grades 8-12. Promote student analytical thinking through an inductive approach to the triangle inequality theorem! Triangle Inequality Theorem Investigation is a great introduction to the triangle inequality theorem and can help in scaffolding this concept for students who need concrete, hands-on examples. Each student will take three pieces of uncooked spaghetti and will follow the instructions on the activity sheet with a rul

Differentiate and add versatility to helping students practice using the area of a sector and arc length formulas. Students will draw three slips; one radius slip, one arc measure slip, and one Find the... slip. Students will use the slip to find either the area, circumference, area of a sector, or arc length depending on what the slips direct them to do. Students will then return the slips to the cups and draw again. This activity includes: Teacher instructions, student worksheet, radius,

This logic statements activity is for students in grades 8-12. Students practice applying various types of logic statements including conditional, converse, inverse, contrapositive, biconditional, and laws of detachment and syllogism in the context of a story. Conditional statements are written in bold and students are prompted to fill in blank spaces using the indicated logic statement. In addition students can write their own logic stories by inserting conditional, converse, inverse, cont

Points, Lines, Planes, and Segments in the Classroom! Geometry practice for grades 8-12. Promote student analytical thinking through identifying basic Geometric figures in the world around them! Points, Lines, Planes, and Segments in the Classroom is an excellent formative assessment for students learning new Geometry vocabulary. This activity can be completed individually or in pairs. You can also extend the activity through small group discussions where students share and explain their choic
