4.NF.3:
Number And Operations - Fractions
Build Fractions From Unit Fractions By Applying And Extending Previous Understandings Of Operations On Whole Numbers.
Understand a fraction a/b with a > 1 as a sum of fractions 1/b. a.
4.NF.4:
Number And Operations - Fractions
Build Fractions From Unit Fractions By Applying And Extending Previous Understandings Of Operations On Whole Numbers.
Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.
4.MD.3:
Measurement And Data
Solve Problems Involving Measurement And Conversion Of Measurements From A Larger Unit To A Smaller Unit.
Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
5.NF.2:
Number And Operations - Fractions
Use Equivalent Fractions As A Strategy To Add And Subtract Fractions.
Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions
5.NF.1:
Number And Operations - Fractions
Use Equivalent Fractions As A Strategy To Add And Subtract Fractions.
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)
