  1. 1. Math 7 Tutoring April 17, 2011
  2. 2. Objectives <ul><li>1. The student will learn the order of operations. </li></ul><ul><li>2. The student will solve for equations. </li></ul><ul><li>3. The student will review perimeter, area and circumference. </li></ul>
  3. 3. Review of Lesson 1 <ul><li>Describing Patterns </li></ul><ul><li>2, 4, 6, 8, 10…… </li></ul><ul><li>100, 50, 25….. </li></ul><ul><li>19, 16, 13…… </li></ul>
  4. 4. Review of Lesson 2 <ul><li>Variables </li></ul><ul><li>A variable is a letter that is used to represent a number </li></ul><ul><li>A variable expression consists of numbers, variables and operations. 2+a=7 </li></ul><ul><li>To evaluate a variable expression substitute values for the variables and simplify your answer. </li></ul><ul><li>Solve: 20/n=10 </li></ul>
  5. 5. Powers and Exponents <ul><li>A power is a way of writing repeated multiplication. </li></ul><ul><li>An exponent tells you how many times to multiply the base number </li></ul><ul><li>Solve: 2^3 </li></ul>
  6. 6. Order of Operations <ul><li>PEMDAS </li></ul><ul><li>Please Excuse My Dear Aunt Sally </li></ul><ul><li>Solve: 2(3+5) </li></ul>
  7. 7. Equations <ul><li>An equation is a mathematical sentence formed by setting two expressions equal. </li></ul><ul><li>The solution of an equation is a number that you can substitute for the variable to make the equation true. </li></ul>
  8. 8. Equations <ul><li>You can use mental math to solve some equations….for example: </li></ul><ul><li>a+20=25 we know that a must be 5 to make this equation true </li></ul><ul><li>Check your answer </li></ul><ul><li>5+20=25…is this a correct equation? </li></ul>
  9. 9. Equations <ul><li>Solving word problems </li></ul><ul><li>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? </li></ul><ul><li>Distance = rt (rate x time) </li></ul><ul><li>80=20t </li></ul><ul><li>80=20 x 4 </li></ul><ul><li>It would take 4 hours to swim 80 miles </li></ul>
  10. 10. Perimeter and Area <ul><li>Perimeter </li></ul><ul><li>Rectangle: 2 l+2w Square: 4s </li></ul><ul><li>8in </li></ul><ul><li>4in </li></ul><ul><li>3in </li></ul>
  11. 11. Perimeter and Area <ul><li>Area: </li></ul><ul><li>Rectangle- A= lw Square: A= s^2 </li></ul><ul><li>Rectangle Length=12in Width=4in </li></ul><ul><li>Square side= 6m </li></ul>
  12. 12. Circumfrence <ul><li>Pi=3.14 pi x diameter </li></ul><ul><li>pi x radius </li></ul><ul><li>Ll Radius </li></ul><ul><li>Diameter </li></ul>3in 6in
  13. 13. Conclusion <ul><li>After viewing this presentation, the student will be able to solve problems of equations, perimeters, and circumferences. </li></ul>
