Two Dimensional Shapes
We're doing polygons in geometry, and apparently I was supposed to learn this in elementary school. I seriously didn't learn anything in elementary school...this is new to me lol. But it's okay I'll learn :) Hold on...is this right? My geometry teacher seriously told us 11 sides was an elevenagon. Sigh.
Common Core Math Standard: 4.G.2: Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles. This book is an excellent resource for elementary school students because it integrates math and English Language Arts in an engaging way. The story is well written and helps students learn about two-dimensional shapes and properties.
A fun way to use K'nex in the classroom is during a geometry lesson on shapes and angles! This activity helps students make, understand and see the different shapes and angles. 4.G.1: Draw points, lines, line segments, rays, angles, and perpendicular and parallel lines. Identify these in two-dimensional figures. 4.G.2: Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size.
