Ideas for Progress: Range 13–15

ACT Explore/ACT Plan/The ACT Mathematics

Entries followed by a dagger (†) apply to the ACT Mathematics Test only.

To enhance their skills in each mathematics-related strand, students who score in the 13–15 score range may benefit from activities that encourage them to do the following:

Score Range 13–15
Basic Operations & Applications
  • investigate and build understanding of the concept of percentage as a comparison of a part to a whole
  • use multiple operations to solve multistep arithmetic problems
Probability, Statistics, & Data Analysis
  • solve real-world problems that involve measures of central tendency (e.g., mean, median, mode)
  • interpret data from a variety of displays (e.g., box-and-whisker plot) and use it along with additional information to solve real-world problems
  • conduct simple probability experiments and represent results using different formats
Numbers: Concepts & Properties
  • recognize and apply place value, rounding, and elementary number theory concepts
Expressions, Equations, & Inequalities
  • use mathematical symbols and variables to express a relationship between quantities (e.g., the number of 59¢ candy bars that you can buy for $5 must satisfy 59n ≤ 500)
  • evaluate algebraic expressions and solve simple equations using integers
Graphical Representations
  • locate and describe objects in terms of their position on the number line and on a grid
Properties of Plane Figures
  • describe, compare, and contrast plane and solid figures using their attributes
  • distinguish between area and perimeter, and find the area or perimeter when all relevant dimensions are given
  • recognize functions as mappings of an independent variable into a dependent variable†
