8th grade · The Number System
Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.
5 interactive, auto-graded activities for 8th grade students practising 8.NS.A.1. Mini Labs put the standard to work in a real scenario; Skill Practice builds fluency on the standard alone. Every one is randomized per student, so each learner gets their own numbers.
Explore rational and irrational numbers through an interactive decimal slider! Students reveal digits, spot repeating or terminating patterns, and classify numbers. A hands-on way to understand decimal behavior and the difference between rational and irrational numbers.
Challenge your students to classify decimals as rational or irrational! In this interactive worksheet, students examine non-terminating decimals—some repeating, some not—to decide which can be written as fractions. A hands-on way to strengthen understanding of decimal patterns and rationality.
Step into the Smoothie Shop and simplify real-world recipe ratios! Students practice reducing fractions to lowest terms using the greatest common factor (GCF). Perfect for introducing or reviewing simplifying fractions through a fun, food-based context.
Practice converting fractions and decimals with this interactive 8th-grade math worksheet. Students convert fractions to decimals and decimals to fractions, identify terminating and repeating decimals, and receive instant feedback. Includes randomization so each student gets unique values, plus a fun pixel-art reveal to boost engagement.
Engage students in adding and subtracting fractions and mixed numbers with this interactive Grade 7–8 math worksheet. Students work with like and unlike denominators, including positive and negative values, and enter answers as simplified fractions only. Built-in randomization gives each student unique problems, and a fun pixel-art reveal boosts motivation.
