    Quarter 3 Math:

    Unit 5: Extend Understanding of Fractions

    4.NF.1- Explain why a fraction is equivalent to another fraction by using area and length fraction models, with attention to how the number and size of the parts differ, even though the two fractions themselves are the same size.

    4.NF.2-Compare two fractions with different numerators and different denominators, using the denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions by: 

    • Reasoning about their size and using area and length models 
    • Using benchmark fractions, 0 1/2 , and a whole 
    • Comparing common numerators or common denominators.

    Unit 6: Making Connections to Decimal Notation

    4.NF.6-Use decimal notation to represent fractions. 

    • Express, model and explain the equivalence between fractions with denominators of 10 and 100. 
    • Use equivalent fractions to add two fractions with denominators of 10 or 100. 
    • Represent tenths and hundredths with models, making connections between fraction and decimals.

    4.NF.7-Compare two decimals to hundredths by reasoning about their size using area and length models, and recording the results of comparisons with the symbols >, =, or <. Recognize that comparisons are valid only when the two decimals refer to the same whole.

    Unit 7: Understanding Operations of Fractions and Decimals

    4.NF.3-Understand and justify decompositions of fractions with denominators of 2, 3, 4, 5, 6, 8, 10, 12, and 100.

    • Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
    • Decompose a fraction into a sum of unit fractions and a sum of fractions with the same denominator in more than one way using area models, length models, and equations.
    • Add and subtract fractions, including mixed numbers with like denominators, by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.
    • Solve word problems involving addition and subtraction of fractions, including mixed numbers by writing equations from a visual representation of the problem.

    4.NF.4-Apply and extend previous understandings of multiplication to:

    • Model and explain how fractions can be represented by multiplying a whole number by a unit fraction, using this understanding to multiply a whole number by any fraction less than one.
    • Solve word problems involving multiplication of a fraction by a whole number.

    Quarter 3 Science:

    Unit 4: Energy, Forces, & Motion

    4.P.3-Recognize that energy takes various forms that may be grouped based on their interaction with matter.

    4.P.1-Explain how various forces affect an object.
