2. Objectives 1. The student will learn the order of operations. 2. The student will solve for equations. 3. The student will review perimeter, area and circumference.

3. Powers A power is a way of writing repeated multiplication. An exponent tells you how many times to multiply the base number Solve: 2^3

4. Order of Operations Please Excuse My Dear Aunt Sally Solve: 2(3+5)

5. Equations An equation is a mathematical sentence formed by setting two expressions equal. The solution of an equation is a number that you can substitute for the variable to make the equation true.

6. Equations You can use mental math to solve some equations….for example: a+20=25 we know that a must be 5 to make this equation true Check your answer 5+20=25…is this a correct equation?

7. Equations Solving word problems A green sea turtle can swim at a speed of 20 miles per hour. How long would it take a green sea turtle to swim 80 miles? Distance = rt (rate x time) 80=20t 80=20 x 4 It would take 4 hours to swim 80 miles

8. Perimeter and Area Perimeter Rectangle: 2 l+2w Square: 4s 8in 4in 3in

9. Circumfrence Pi=3.14 pi x diameter pi x radius Ll Radius Diameter 3in 6in

10. Conclusion After viewing this presentation, the student will be able to solve problems of equations, perimeters, and circumferences.
