UNIT PLAN Grade Level: Unit #: Unit Name: 3 3 Part 1 Geometry-Polygons Big Idea/Theme: The physical world can be described by understanding the connection between the identification of basic attributes and the classification of two-dimensional shapes. Culminating Assessment: Create a picture that includes at least one example of each of the following polygons: Triangles (isosceles, scalene, equilateral, obtuse, acute, right). Quadrilaterals. Pentagons. Hexagons. Octagons. Unit Understanding(s) Students will understand that… Polygons can be classified as triangles, quadrilaterals, pentagons, hexagons, or octagons according to the number of their sides. Triangles can be classified by the length of their sides as scalene, isosceles, or equilateral. Triangles can be classified by the sizes of their angles as acute, obtuse, or right. Unit Essential Question(s): How are polygons classified? How are triangles classified as scalene, isosceles, or equilateral? How are triangles classified as acute, obtuse, or right? Students will know… / Students will be able to… • Explain that an equilateral triangle is a triangle with three equal sides and three equal angles. • Recognize that an isosceles triangle has two equal sides and opposite angles are equal. • Identify a scalene triangle as having no equal sides and no equal angles. • Recall that an acute angle is smaller than a right angle. • Recall that a right angle measures 90º and can be shaped like an L. • Recall that an obtuse angle is larger than a right angle. • Classify triangles by the length of their sides as scalene, isosceles, or equilateral according and by the sizes of their angles as acute, right, or obtuse. • Classify triangles by the length of their sides as scalene, isosceles, or equilateral according to the sizes of their angles as acute, right, or obtuse to solve increasingly more sophisticated problems. South Carolina Academic Standards: 3-4.2 Classify polygons as either triangles, quadrilaterals, pentagons, hexagons or octagons according to the number of their sides. 3-4.5 Classify triangles by the length of their sides as scalene, isosceles, or equilateral according and by the sizes of their angles as acute, right, or obtuse.
