## Add, Subtract, Multiply, Divide Decimals

MCC6.NS.3: Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.Dividing: http://www.khanacademy.org/math/arithmetic/decimals/dividing_decimals/v/dividing-decimalMultiplying: https://www.khanacademy.org/math/arithmetic/decimals/multiplying_decimals/v/multiplying-decimals Adding and Subtracting: https://www.khanacademy.org/math/arithmetic/decimals/adding_decimals/v/adding-decimals

## Divide fractions with models and keep switch flip

MCC6.NS.1: Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. For example, create a story context for (2/3) ÷ (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In general, (a/b) ÷ (c/d) = ad/bc.) How much chocolate will each person get if 3 people share 1/2.b of chocolate equally? How many 3/4-cup servings are in 2/3 of a cup of yogurt? How wide is a rectangular strip of land with length 3/4 mi and area 1/2 square mi? THE FOLLOWING IS A VIDEO TO HELP YOU UNDERSTAND THIS BETTER:http://learnzillion.com/student/lessons/1251

## GFC and LCM and distributive property

MCC6.NS.4: Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1-100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4(9+2). lcm: http://www.khanacademy.org/math/arithmetic/factors-multiples/least_common_multiple/v/least-common-multiple
