Enroll in ACT Mathematics with Dolphin STEM Academy
The ACT Mathematics course was developed by aligning Plato Courseware with the
topics that are assessed on the 2016 ACT Test. Each unit aligns to one or more topics
within the test. This course focuses on the study of algebraic problem-solving skills and
concepts related to geometry, probability, and statistics. In this course, you will find a
variety of lessons and activities to improve your knowledge and skills in these areas.
By the end of this course, you will:
Use addition, subtraction, multiplication, and division to solve real-world problems.
Use fractions to solve real-world problems.
Add, subtract, multiply, and divide decimals using the standard algorithm.
Order rational numbers in real-world situations.
Study absolute values and recognize the difference between absolute value and
statements about order.
Explore common factors and multiples.
