4.NBT.4:
Number And Operations In Base Ten
Use Place Value Understanding And Properties Of Operations To Perform Multi-Digit Arithmetic.
Fluently add and subtract multi-digit whole numbers using the standard algorithm.
4.NF.1:
Number And Operations - Fractions
Extend Understanding Of Fraction Equivalence And Ordering.
Explain why a fraction a/b is equivalent to a fraction (n x a)/(n x 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.
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.MD.2:
Measurement And Data
Solve Problems Involving Measurement And Conversion Of Measurements From A Larger Unit To A Smaller Unit.
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.
