Quiz You buy a present for your math teacher. You only have enough paper to wrap the front of the rectangular box. A piece of rectangular wrapping paper is 2 feet by 8 inches. How many square inches will the wrapping paper cover?

What is the area the paper will cover? To find the amount of square inches, I had to convert the feet to inches. I know there are 12 inches in a foot, so there will be 24 inches in 2 ft. To find the square inches, I found the area of the rectangle. You buy a present for your math teacher. You only have enough paper to wrap the front of the rectangular box. A piece of rectangular wrapping paper is 2 feet by 8 inches. How many square inches will the wrapping paper cover? The paper will cover 192 square inches. 2ft x 8in Rectangle Square Inches

Math Sing-A-Long Project due Monday, January 10 (one week after Christmas break)

Class Work Pythagorean Theorem in the World We are going to walk around the school and find examples of Pythagorean Theorem. Once you find an example, you will take a picture of it. You will use the picture later in a Pythagorean Theorem project.

Class Work Pythagorean Theorem Problems You need a sheet of paper. We will work 4 problems together, and you will work 6 problems on your own.

Pythagorean Theorem 5 c 12 Theorem: a 2 + b 2 = c = c = c = c 2 c = 13 13

Pythagorean Theorem 5 12 b Theorem: a 2 + b 2 = c b 2 = b 2 = b 2 = 119 b = Guess & Check!

Pythagorean Theorem 4 7 b Theorem: a 2 + b 2 = c b 2 = b 2 = b 2 = 33 b = Guess & Check!

Pythagorean Theorem If a 2 + b 2 = c 2, then the triangle is a right triangle. a=4, b=5, c= = = = 64 Not a Right triangle Is a triangle with sides: a = 4, b = 5, c = 8 a right triangle?

Class Work 1 – 3: Solve for the missing side – 6: Determine if the triangles are right triangles. 4. a = 6, b = 8, c = a = 1, b = 3, c = c b a
