3. What’s on the Test? Pre- and Elementary Algebra Pre-Algebra (23%). Questions in this content area are based on basic operations using whole numbers, decimals, fractions, and integers; place value; square roots and approximations; the concept of exponents; scientific notation; factors; ratio, proportion, and percent; linear equations in one variable; absolute value and ordering numbers by value; elementary counting techniques and simple probability; data collection, representation, and interpretation; and understanding simple descriptive statistics. Elementary Algebra (17%). Questions in this content area are based on properties of exponents and square roots, evaluation of algebraic expressions through substitution, using variables to express functional relationships, understanding algebraic operations, and the solution of quadratic equations by factoring.

4. What’s on the Test? Intermediate Algebra and Coordinate Geometry Intermediate Algebra (15%). Questions in this content area are based on an understanding of the quadratic formula, rational and radical expressions, absolute value equations and inequalities, sequences and patterns, systems of equations, quadratic inequalities, functions, modeling, matrices, roots of polynomials, and complex numbers. Coordinate Geometry (15%). Questions in this content area are based on graphing and the relations between equations and graphs, including points, lines, polynomials, circles, and other curves; graphing inequalities; slope; parallel and perpendicular lines; distance; midpoints; and conics.

5. What’s on the Test? Plane Geometry and Trigonometry Plane Geometry (23%). Questions in this content area are based on the properties and relations of plane figures, including angles and relations among perpendicular and parallel lines; properties of circles, triangles, rectangles, parallelograms, and trapezoids; transformations; the concept of proof and proof techniques; volume; and applications of geometry to three dimensions. Trigonometry (7%). Questions in this content area are based on understanding trigonometric relations in right triangles; values and properties of trigonometric functions; graphing trigonometric functions; modeling using trigonometric functions; use of trigonometric identities; and solving trigonometric equations.

6. Math Strategies Back-solving Calculate Wisely Encourage Your Inner Artist Target Practice

7. Math Strategies: Backsolving Backsolving is trying each answer option and seeing if it works. Although this may sound time-consuming, it comes in handy when trying to answer questions that have numbers as answer options. For instance, if you apply the number in option C to the problem and it is the answer, you’re golden! If not, you should have more of an idea of which way to go

8. How Does it Work? Daniel arranged 4 bags and put 40 marbles in the bags in such a way that each bag had 2 more marbles than the previous bag. How many marbles are there in the third bag? a.5 b.8 c.10 d.11 e.21 Apply the number in option C to the problem: If there are 10 marbles in the 3rd bag, there should be 8 in the 2nd, 6 in the 1 st and 12 in the 4 th. Hence: 6+8+10+12=36 C is NOT your answer

9. Math Strategies: Plug It In Use this strategy for critical thinking problems. For example: (change ex) √√√ a>0 and b<0 What would (a*b)/b yield? Your only options are either a positive or a negative number.

10. Math Strategies: Calculate Wisely Math questions on the ACT are designed to be answered within a minute, if that. They do not involve intense calculate. If you find yourself reaching for a calculator so you can figure out the square root of 934, you probably made a mistake somewhere. No calculation on the test should be THAT difficult. On the other hand, please don’t waste your time calculating information that you already know. If you can’t figure out 2+2 by this point in your life, then there may be some underlying issues.

11. Calculator Tips Don’t purchase a new calculator just for the ACT or the SAT. Use the calculator that you know and understand! Make sure your calculator has new batteries. You’d be in hot water if your calculator died during one of those assessments!

12. Math Strategies: Visualize Scribble space will be provided If you are having a hard time visualizing a shape in your head, draw it out. Don’t waste time making it perfect. No one will ever see your test booklet except you. Do what you need to get the answer right: no more, no less! Do your figuring here

13. A Visualization Example In order to find the length of a side, draw a picture Example: A ladder is leaning against a 12 foot wall, and is 5 ft away from the base of the wall. How long is the ladder? 12ft 5ft Use the Pythagorean Theorem to determine this answer… (a*a)+(b*b)=(c*c) (5*5)+(12*12)=(C*C) 25+144=(C*C) 169=(C*C) √169= √C 13=C The ladder is 13ft long

14. Math Strategies: Target Score If you are looking to score a 19-23 on the Math Test, there is no need to look for shortcuts because there is no need to race through the test. Focus on getting 32-39 questions right! If you are looking to score a 27 or higher on the Math Test, you shouldn’t be working out every question. Find quicker ways to answer questions because these faster methods will give you the time you need to make it to the last few classes.
