In this understanding the y-intercept worksheet, students solve 13 various problems defining the y-intercept of a line using data tables. They complete the table that illustrates the relationship between the number of sides of a polygon and the number of diagonals that can be drawn from one vertex to its interior. Then, students draw a graph the best represents this information and define trend line.
Get your pupils out of their seats by having them create a cheer complete with arm movements that demonstrate various angles. Working in small groups either during class or recess, young geometers are tasked with having to create a cheer that models right, obtuse, acute, and straight angles. Tip: This lesson can be extended to have multiple learners create other geometric constructs such as parallel or perpendicular lines, vertical angles, and complementary or supplementary angles.
In this graphing special lines instructional activity, students solve 18 short answer and graphing problems. Students graph lines given two points. Students find the slope of a line given two points. Students determine if two lines area parallel, perpendicular, the same line, or none of the above.
A Jeopardy-style math presentation awaits your class. This engaging PowerPoint presents nine slides on geometry. The categories are: Triangles, Quadrilaterals, and Lines and Angles. Players should gain increased understanding of geometric terms from completing this game.
In this geometry lesson, young scholars collect and analyze data as they investigate relationships between the pre-image and the image of a triangle. They investigate angle measures, side lengths, and the dilation factor. The dynamic nature of Cabri Jr. allows students to form and verify conjectures regarding dilations.
