1. SOS Tutoring Grade Nine Math MPM1D

2. What’s SOS? • Students Offering Support • University student run charity • Raising money to build a school/community centre in Haiti

3. Who Are We? • Jessye Nielsen, second year neuroscience and psychology student at U of T • Phillip Ko

4. MATH! What is it GOOD for? • When/where will I ever have to use this again?! ANYTIME AND EVERYWHERE!

5. Major questions? What are you most worried about for your exam?

6. Number Sense and Algebra Topics • Evaluating algebraic expressions • Exponent rules • Simplification of expressions with rational numbers and integers • Operations using polynomials with two variables • Multiplying polynomials by monomials • Expanding polynomials and simplifying • First degree equation solving with fractional coefficients • Problem-solving!

7. Exponent Rules • Addition • Multiplication • Division • Power of a Power Practice Questions

8. Simplification • Basic simplification • With rational numbers and integers

9. Polynomials! • Two variable equations • (Polynomial) x (monomial) • Expansion and simplification

10. Fractional Coefficients • Simplification • Problem solving

11. Any questions?

12. Linear Relations Topics • Understanding data (inferences, trends etc.) • Tables of Values • Graphing • Properties of linear relationships • y=mx+b

13. Data • What does it mean? • Patterning • Describing data

14. Table of values • Pattern finding • Slope and intercepts

15. Graphing • From raw data • From a table of values Types of Graphs • Scatterplots • Bar graphs

16. Y=MX+B • M= slope • B= y-intercept • (X,Y) is a point on the line

17. Slope and Y-Intercept Slope • Rise/run=M • (Y2-Y1)/(X2-X1)=M Requires two points on the line Y-Intercept • The value of y when x=0 Practice Questions!

18. ANY QUESTIONS?

19. Applications with Lines • Different equations of a line • Rates of Change • Problem-solving • What does it all mean?

20. Different Equations of a Line • Ax+By+C=0 • X=A • Y=B

21. Rates of Change • How do we describe changes in the line? -speed -size etc. • Therefore a rate of change is equal to the ________!

22. Other Applications • Distances Practice questions 

23. Any QUESTIONS?

24. Geometry • Pythagorean theorem • Maximum areas • Minimum perimeters • Surface areas • Volumes • Angles

25. Pythagorean Theorem • A^2+B^2=C^2 • Applications

26. Maximum Areas • Perimeter is given • Method: Constructing rectangles

27. Minimum Perimeter • Area is given • Method: Constructing rectangles

28. Surface Area • Cubes • Prisms • Spheres • Cones

29. Volumes • Cubes • Prisms • Spheres • Cones

30. Angles • Triangles -Isosceles -Equilateral -Acute • Quadrilaterals • Other polygons

31. SOHCAHTOA • SOH • CAH • TOA

32. ANY QUESTIONS?

33. Exam Tips • Do SLEEP. • Don’t cram hours and hours the night before. • Do EAT. • Don’t panic. • Do take your time. • Don’t waste time at the beginning struggling with questions. Do the ones you know first.

34. GOOD LUCK!!
