4.OA.1:
Operations And Algebraic Thinking
Use The Four Operations With Whole Numbers To Solve Problems.
Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 x 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.
4.OA.3:
Operations And Algebraic Thinking
Use The Four Operations With Whole Numbers To Solve Problems.
Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
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.
5.NBT.7:
Number And Operations In Base Ten
Perform Operations With Multi-Digit Whole Numbers And With Decimals To Hundredths.
Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
5.NF.3:
Number And Operations - Fractions
Apply And Extend Previous Understandings Of Multiplication And Division To Multiply And Divide Fractions.
Interpret a fraction as division of the numerator by the denominator (a/b = a / b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem. For example, interpret 3/4 as the result of dividing 3 by 4, noting that 3/4 multiplied by 4 equals 3, and that when 3 wholes are shared equally among 4 people each person has a share of size 3/4. If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie?
5.NF.4:
Number And Operations - Fractions
Apply And Extend Previous Understandings Of Multiplication And Division To Multiply And Divide Fractions.
Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
