TAKS Exit Review Math by Morrison 2012 © Math by Morrison 2011-12 Instructions After reading through the question, click the screen for helps and hints to appear. Find out why an answer is incorrect, and learn how the TAKS test will attempt to trick you. Pay careful attention, and you will have a practice quiz once you have finished the slide show. TAKS Exit Review Ready to Begin? Lesson 1-4 1. Joann can write 4 problems in 3 minutes. At this rate, about how long will it take her to write 8 sets of 5 problems? 8 x 5 = 40 Be careful….not all rate problems are set up to solve. Make sure you know exactly how many problems Joann is planning toHINTS write! CONTINUE CLICKING SCREEN FOR HELP AND Problems Minutes A B C D 30 minutes 6 minutes 39 minutes 53 minutes 4 3 40 x Correct Answer! Did not multiply: 8 x 5 = 40 problems Solve proportions by cross multiplication Proportion upside down 2. Which of the following is the front view of the 3-D object shown below? Make sure you carefully note where the FRONT of the object is located. Sketch a drawing if you need CONTINUE CLICKING SCREEN FOR HELP AND HINTS help. This is the top view Correct Answer! This is the left view F G H LEFT FRONT Not sure what this is… J 3. Which expression represents the perimeter of the isosceles triangle below, in terms of x? An isosceles triangle has 2 congruent sides and two congruent angles. x+5 x+5 x CONTINUE CLICKING SCREEN FOR HELP AND HINTS A B C D 2x + 5 3x + 5 ½(x2 + 5x) 3x + 10 To find perimeter, find the sum of all sides. Only combine like terms! Triangles have 3 sides… The missing side has a length of x + 5 This used the AREA formula Correct Answer! 4. Find the slope of the linear equation: 12x – 4y = 24 Slope is the rate of change, To find slope, m, from standard form and often called rise/run [ax + by = c], use the formula m = -a/b It might be easier to remember to say “opposite of x over y” CONTINUE CLICKING SCREEN FOR HELP AND HINTS In slope-intercept form [y = mx + b], the coefficient on the x is the slope! F G H J 12 -3 3 2 In standard form, the coefficient on the x is not the slope OPPOSITE of x over y: -12/-4 = 3 Correct Answer! When finding slope, the constant (24) should not be used 5. What is the ratio of faces to edges of a triangular pyramid? Anface A ratio edge isisis the a where comparison flat surface two of abetween faces 3-D meet object two in numbers a line Sketch out a triangular pyramid and then count faces and edges. CONTINUE CLICKING A triangular SCREEN pyramid FORhas HELP a AND HINTS trianglular base and all sides meet in a single point A B C D 1:1 2:3 3:2 3:4 Ratio of faces to vertices is 1:1 This is the ratio of edges to faces Correct Answer! Not sure where this came from Faces: 4 Edges: 6 Vertices: 4 TAKS Exit Review Math by Morrison 2012 This completes today’s slide show. It is now time for Quiz 1-4.
