This is our next unit that we began working on last week. For sixth graders the expected fluencies are multi-digit whole number division and multi-digit decimal operations. Procedural fluency is defined by the Common Core as “skill in carrying out procedures flexibly, accurately, efficiently and appropriately”. Last week we concentrated on multi-digit whole number division. This week we will practice with the decimal operations - adding, subtracting, multiplying, and dividing- and practice dividing fractions! Students have TenMarks lessons loaded for these two skills. If a student does not achieve a score of 80% or above, I have reloaded the skill on TenMarks for more practice. Email me if your student does not remember his/her login information. In this unit students will: **Find the greatest common factor of two whole numbers less than or equal to 100 **Find 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. **Interpret and compute quotients of fractions **Solve word problems involving division of fractions by fractions using visual fraction models and equations to represent the problem. **Fluently divide multi-digit numbers using the standard algorithm **Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. Standards and I CAN statements MCC6.NS.1 - Interpret quotients of fractions, and solve word problems involving division of fractions by fractions. I can solve word problems involving division of fractions by fractions. I can represent the context of a fraction word problem using a variety of models. MCC6.NS.2 - Fluently divide multi-digit numbers using the standard algorithm. I can fluently divide multi-digit numbers. MCC6.NS.3 - Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. I can fluently add, subtract, multiply, and divide multi-digit decimals. 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. I can find the greatest common factors of two whole numbers (up to 100). I can find the least common multiple of two whole numbers (less than or equal to 12). I can use the distributive property to express a sum of two whole numbers. Vocabulary Algorithm: a step-by-step solution to a problem. Difference: The amount left after one number is subtracted from another number. Distributive Property: The sum of two addends multiplied by a number is the sum of the product of each addend and the number. Dividend: A number that is divided by another number. Divisor: A number by which another number is to be divided. Factor: When two or more integers are multiplied, each number is a factor of the product. "To factor" means to write the number or term as a product of its factors. Greatest Common Factor: The largest factor that two or more numbers have in common. Least Common Multiple: The smallest multiple (other than zero) that two or more numbers have in common. Minuend: The number that is to be subtracted from. Multiple: The product of a given whole number and an integer. Quotient: A number that is the result of division. Reciprocal: Two numbers whose product is 1. Sum: The number you get by adding two or more numbers together Subtrahend: The number that is to be subtracted. Product: A number that is the result of multiplication.
