Description
Absolute Value and Opposites of Rational Numbers (Grade 6–7) Help students make sense of absolute value as distance and opposites (additive inverses) with a mixed set of engaging questions on fractions and decimals. Students compute, compare, order, interpret distance on a number line, and reason about when absolute-value equations do and do not have solutions. What’s inside 1. 30 self-checking multiple-choice cards 2. Compute ∣𝑥∣ for decimals & fractions 3. Identify opposites and “opposite of the opposite” 4. Distance on the number line (right/left language, real-world: temperature, elevation, bank balance) 5. Order/compare by absolute value vs. actual value 6. One-step absolute-value equations like ∣𝑥−4∣=1.5 7. Concept checks (e.g., why ∣x∣=−3 has no solution) 8. Spiral difficulty: from quick wins to deeper reasoning 9. Auto-grading with immediate feedback; randomized answer options Skills & Big Ideas 1. Absolute value as distance from 0 2. Opposites/additive inverses (a and −a) 3. Interpreting “to the right/left” as add/subtract on the number line 4. Distinguishing ∣a∣ from a (sign vs. magnitude) 5. Decimals & fractions in context (temperature, elevation, money) How to use 1. Warm-up, independent practice, stations, exit tickets, or homework 2. Great for reteach/enrichment; turn the concept checks into quick discussions Standards alignment CCSS: 6.NS.C.5, 6.NS.C.6, 6.NS.C.7; links to 7.NS.A.1 (distance/absolute value in additive contexts)
