Concepts: Need to know about (Nouns) • Rational numbers: Ratios, proper and improper fractions, mixed numbers, decimals, percents • Least Common Multiple, Greatest Common Factor • Equivalent Values • Scientific Notation • Absolute Value Skills: Be able to do (Verbs) • Compare and order rational numbers using =, ≠, <, ≤, >, ≥ • Convert fractions, decimals, percents • Order rational numbers with or without a number line • Write numbers in scientific notation and translate to standard form • Understand the concept of absolute value Identifying Big Ideas from Unwrapped Standards: 1. A rational number is a number that has a location on the real number line and can be written as a ratio, fraction, decimal, or percent. 2. Rational numbers are compared by converting among forms to find equivalent values. 3. Rational numbers are ordered from least to greatest on a real number line. 4. Scientific notation is a shorthand way of writing numbers using powers of 10. Essential Questions from Big Ideas to Guide Instruction and Assessment: 1. What is a rational number? 2. How do you compare rational numbers? 3. How are rational numbers ordered? 4. What is scientific notation?
