Lesson 3 -
Fraction and Whole Number Multiplication
Lesson 4 - Investigate - Multiply Fractions
2/3 x 1/4
1. shade 2/3 going horizontally
2. shade 1/4 going vertically
3. total rectangles made is 12 (this becomes the denominator)
4. count the number of squares that are both yellow and colored over by the black (this becomes the numerator)
answer is 2/12 and simplified is 1/6
Lesson 5 - Compare Fraction Factors and Products
Fraction times one will always be that fraction.
The product of a fraction times a whole number will always be greater than the fraction.
The product of a fraction times a fraction will always be less than either of the fractions.
Lesson 6 -

Lesson 7 - Investigate - Area and Mixed Numbers
Lesson 8 - Compare Mixed Number Factors and Products
The product of a mixed number times one will always be that original mixed number.
The product of a mixed number times another mixed number will always be greater than the original mixed numbers.
The product of a mixed number times a fraction (less than one) will always be less than the original mixed number.

Standards
The following are the standards that we will be addressing in Chapter 7. Please let me know if you or your child has trouble with any of the assignments.
Common Core Standards
All mathematical practices will be addressed throughout the chapter.
Lesson 7.1, 7.2, 7.3, 7.4, 7.6, 7.7, 7.10
5.NF.4 Apply and extend previous understanding of multiplication to multiply a fraction or whole number by a fraction.
Interpret the products (a/b) x q as a part of a partition of q into b equal parts; equivalently, as the result of a sequence of operations a x q ÷ b.
Find the area of a rectangle with fractional side lengths by tiling it with unit squares of the appropriate unit fraction side lengths, and show that the area is the same as would be found by multiplying the side lights. Multiply fractional side lengths to find area of rectangles, and represent fraction products as rectangular areas.
Lesson 7.5, 7.6, 7.8
5.NF.5 Interpret multiplication as scaling (resizing) by:
Comparing the size of a product of the size one factor on the basis of the size of the other factor, without performing the indicated multiplication.
Explaining why multiplying a given number by a fraction greater than 1 results in a product greater than the given number (recognizing multiplication by whole numbers greater than 1 as a familiar case); explaining why multiplying a given number by a fraction less than 1 results in a product smaller than the given number; and relating the principle of fraction equivalence a/b =(nxa)/(nxb) to the effect of multiplying a/b by 1.
Lesson 7.9, 7.10
5.NF.6. Solve real world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fractions models or equations to represent the problem.
