You are purchasing an editable set of the Google Slides used to make the video - 5 Steps to Subtract Rational Numbers in Fraction Form | Grade 7 Math | 7.NS.A.1 . All slides are animated as seen in the video lesson. You may use these slides as a guided lesson, scaffolded class notes, print or share student practice slides as task cards, and/or adapt using Pear Deck for whole class instruction.
In this math video we will learn 5 steps to subtract rational numbers in fraction form. Step 1: If necessary, write mixed numbers as improper fractions. Step 2: If necessary, rewrite fractions to have a common denominator. Step 3: If necessary, rewrite subtraction as addition. Keep the first number the same, change the subtraction sign to addition, and change the sign of the second number to its opposite. Step 4: Add the numerators using integer rules and keep the denominator. The integer rules for adding are : Same Signs Rule - Find the absolute value of the numerators. Add. Then, use the common sign from the original numerators. Different Signs Rule - Find the absolute value of the numerators. Subtract the smaller from the larger. Use the sign of the numerator that has the larger absolute value. Step 5: If necessary, simplify the fraction. A graphic organizer will be used and modeled along with the procedural checklist. Four practice problems, two with same signs and two with different signs, will be presented and modeled with explanations.
