Overview:

Take the court with retired NBA star and current basketball analyst Kendall Gill to learn about the science of the perfect shot. We use angles every day—to build ramps and slides, steer a car, shoot basketballs, throw baseballs, and kick soccer balls. In fact, the science of angles is in almost every sport we play and every movement we make, so go out and play a game with your kids.

Content Standard(s):
 Mathematics MA2019 (2019) Grade: 4 24. Identify an angle as a geometric shape formed wherever two rays share a common endpoint. Unpacked Content Evidence Of Student Attainment:Students: Describe an angle. Describe an angle's relationship to a circle.Teacher Vocabulary:Angle Ray Endpoint Geometric shape Vertex Line Point Line segmentKnowledge:Students know: Angles are geometric shapes formed when two rays share a common endpoint. How to draw points, lines, line segments, and raysSkills:Students are able to: Identify an angle as two rays with a common endpoint.Understanding:Students understand that: angles are geometric shapes made of two rays that are infinite in length and are measured with reference to a circle with its center at the common endpoint of the rays.Diverse Learning Needs: Essential Skills:Learning Objectives: M.4.24.1: Define degree, angle, ray, and vertices. M.4.24.2: Recognize and draw shapes having specified attributes such as a given number of angles or a given number of equal faces. M.4.24.3: Estimate angle measures using 45o, 90o, 180o, 270o, or 360o. M.4.24.4: Identify angle, ray, and vertices. M.4.24.5: Draw shapes to possess defining attributes. Prior Knowledge Skills:Build and draw shapes to possess defining attributes. Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles). Model partitioning circles and rectangles. Decompose pictures made of simple shapes. Identify squares, circles, triangles and rectangles. Explore shapes or figures that can be decomposed into smaller equal parts. Alabama Alternate Achievement Standards AAS Standard: M.AAS.4.24 Recognize and Identify angles in geometric shapes as larger or smaller.
