**QUESTION OFTEN ASKED BY PARENTS:**What was wrong with how we used to do fraction division or long division?**ANSWER:**Memorizing a method (called a standard algorithm) wasn't learning or understanding. Kids forget the method quickly, get lost in a long series of steps, and cannot judge the reasonableness of their answers because they never understood what was going on in the first place.**IN THIS UNIT, STUDENTS WILL BE EXPECTED TO:**

- 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.

- Convert a rational number to a decimal using long division.

- Identify terminating or repeating decimal representations of rational numbers.

- Solve real-world and mathematical problems involving the four operations with rational numbers.

- Use and apply order of operations to solve problems involving rational numbers.

- 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 greatest common factor and the least common multiple to solve problems.

- 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 the quotients of fractions.

- Solve word problems involving division of fractions by fractions using visual fraction models and equations to represent

the problem.
