About this book
Each test checks one chapter, from scientific notation to two-way tables and relative frequency. Together they make a full review before high school.
Each test lists its time (45 minutes) and its total of 20 points on its first page, then mixes short questions and multi-part problems, like Dilate a figure in the Dilations and Similar Figures test. Part 2, from page 68, holds the answer keys: worked solutions and a scoring note for every question.
For an eighth grader preparing for high school math, a parent, or a tutor. Pair it with the Grade 8 Math Worksheets with Answers to go back to the lesson when a problem gets stuck.
