Monday, February 3, 2014  Finding Area of Trapezoids
Bell Work  Week 11 from Holt textbook p. GA14.
3rd and 4th Period
Classwork  Completed Milliken p.26 "Area of Trapezoids" in group.
Homework  p.30 "Area of Parallelograms, Triangles, and Trapezoids" #110. Show organized work.

5th and 6th Period
Classwork  Graded work from Friday, guided practice ppt #110, was returned, reviewed and completed. Students shared different ways for finding the area of trapezoids. Students then worked in group to complete p.26 "Area of Trapezoids."
Homework: p.26 "Area of Trapezoids" 5th Period  Answers for #13 were given. Student work should demonstrate how to get these solutions. 6th Period  Complete #19. Show organized work.

Below are examples from some amazing students on how to find the area of trapezoids using "Area of Trapezoids Notes."
Problem 7. There are multiple ways to find the area of a trapezoid so long as you have the necessary information.
On the left, Jack found the area of the trapezoid by dividing the polygon into two triangles.
On the right, Daja demonstrates how to find the area by using the formula, area equals the sum of the area of the first triangle and the area of the second triangle. Using the distributive property, the common factors, 1/2 and the height of the triangles, are pulled in front of the parenthesis to be multiplied with the sum of the two bases. Definition of the Distributive Property: The sum of two addends multiplied by a number is the sum of the product of each addend and the number.
In the middle, Beatriz and Jackson show how to find the area by dividing the trapezoid into two triangles and a square.
