Subject: Geometry / Monday / Tuesday / Wednesday / Thursday / Friday
ACCRS: / [G-CO11] Prove theorems
about parallelograms.
Theorems include: opposite
sides are congruent, opposite angles are congruent, the diagonals of a parallelogram bisect each other, and conversely, rectangles are parallelograms with congruent diagonals. / CCRS 34.) Determine areas and perimeters of regular polygons, including inscribed or circumscribed polygons, given the coordinates of vertices or other characteristics. / CCRS 21.) Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems. / CCRS 21.) Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems. / CCRS 34.) Determine areas and perimeters of regular polygons, including inscribed or circumscribed polygons, given the coordinates of vertices or other characteristics.
Before: / Unit 6 Test / Students will learn to solve areas of parallelograms. / Quiz on Areas of Parallelograms and triangles / Students will solve areas of parallelograms.
During: / Quadrilaterals Test / Area of Parallelograms and Triangles / Students will use the Pythagorean theorem to derive a formula for what happens when you have 45-45-90 and 30-60-90 triangles / Solving 45-45-90 and 30-60-90 triangles around the room. / Area of Trapezoid, Rhombus, Kites
After: / Quadrilaterals Test / “Areas of Parallelograms & Triangles” Worksheet / 45-45-90 and 30-60-90 Triangles examples / Quiz: 30-60-90 and 45-45-90 / Worksheet over finding areas of traps, rhombi, kites
Desired Outcome: / Students will show a mastery of skills that they have learned with quadrilaterals. / Students will be able to determine the area of parallelograms and triangles. / Students will be able to solve 45-45-90 and 30-60-90 triangles. / Students will be able to solve 45-45-90 and 30-60-90 triangles. / Students will be able to determine the area of all quadrilaterals.
Formative/Summative / Quadrilaterals Test / Quiz: 30-60-90 and 45-45-90
