1 UNIT 1: Integers & Rational Numbers Total Number of Days: 4 weeks Grade/Course: 7A / General Math ESSENTIAL QUESTIONS ENDURING UNDERSTANDINGS How are integers and whole numbers alike and different? What do negative numbers represent? Integers are useful for noting relative changes or values. Every numerical operation has an inverse. Mathematical properties reveal multiple appropriate methods to compute. Rational numbers can be expressed in multiple ways. PACING CONTENT SKILLS STANDARDS (CCCS/MP) RESOURCES LEARNINGACTIVITIES/ ASSESSMENTS Holt Math Course2 OTHER (e.g., tech) Integers Compare and order integers Graph and order integers on a number line NSA.2a NSA.2b NSA.2c NSA.2d NSA.3 (See appendix for definition and sample problems) Pg. 72 – 75 Using a poster thermometer ask the students what the temperature might be on a hot sunny day? Ask them what it means for the temperature to be 10 degrees below zero. Next ask them where 15 degrees below zero is on the thermometer and whether it is hotter or colder than 10 degrees below zero. Explain that since 15 degrees below zero is colder (less temp) then 10, -15 < - 10. Turn the thermometer sideways so it becomes a number line.

Give each student an index card with an integer written on it. Without talking, students must line themselves up in order from smallest to largest. http://www.mathplayground.com/nu mberballs.html http://www.primaryresources.co.uk/online /negnumorder.swf http://www.ixl.com/math/grade- 7/absolute-value-and-opposite- integers Formative Assessment: Integer Operation
