3-5-2012 Grade 6 Factoring Flawless Fractions


Teching the Core Curriculum Content Standards
Math Standards: Grade 6 - The Number System
Standards: 6.NS.1

STRAND
STANDARD
CPI: SKILLS
RESOURCES
The Number System
The goal -
Student will apply and extend previous understandings of multiplication and division to divide fractions by fractions, multiply and divide multi-digit numbers and find common factors and multiples, and apply   and extend previous understandings of numbers to the system of rational numbers.
More specifically students use the meaning of fractions, the meanings of multiplication and division, and the relationship between multiplication and division to understand and explain why the procedures for dividing fractions make sense. Students use these operations to solve problems. Students extend their previous understandings of number and the ordering of numbers to the full system of rational numbers, which includes negative rational numbers, and in particular negative integers. They reason about the order and absolute value of rational numbers and about the location of points in all four quadrants of the coordinate plane.
Apply and extend   previous understandings of multiplication and division to divide fractions by fractions.
Math fact practice-multiplication: A+Plus Math

6.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) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (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 lb 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? Compute fluently with multi-digit numbers and find common factors and multiples.
