Unit: Fraction Cards and Decimal Squares (Unit 6 (Week 25, 7 Weeks)




Big Ideas

The students will understand that:


  • Fractions are equal parts, equivalent fractions have the same value, even though they may look different, and fractions can be combined with denominators that are the same as well as different

  • Decimals are an extension of the place-value system

Essential Questions

What is the meaning of fractions and decimals and how do they relate to my life?

How does comparing quantities describe the relationship between them?

What are ways to represent rational numbers when adding?

 

 



Common Core Standards and Indicators

CCLS:Mathematics, 4th Grade , Mathematical Practice

The Standards for Mathematical Practice describe varieties of expertise that mathematics educators at all levels should seek to develop in their students.



  •  2. Reason abstractly and quantitatively.

  •  3. Construct viable arguments and critique the reasoning of others.

  •  4. Model with mathematics.

  •  5. Use appropriate tools strategically.

  •  6. Attend to precision.

  •  7. Look for and make use of structure.

CCLS:Mathematics, 4th Grade , Number & Operations—Fractions

4.NF Extend understanding of fraction equivalence and ordering.


  •  1. Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.


  •  2. Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or

4.NF Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers.

  •  3. Understand a fraction a/b with a > 1 as a sum of fractions 1/b.

  •  3a. Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.

  •  3b. Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model.

  •  3d. Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem.

  •  4. Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.

  •  4c. Solve word problems involving multiplication of a fraction by a whole number, e.g., by using visual fraction models and equations to represent the problem.

4.NF Understand decimal notation for fractions, and compare decimal fractions.

  •  5. Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100.
  •  6. Use decimal notation for fractions with denominators 10 or 100


  •  7. Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or

CCLS:Mathematics, 4th Grade , Measurement & Data

4.MD Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit.



  •  2. Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.
