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.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.2:
Number And Operations - Fractions
Extend Understanding Of Fraction Equivalence And Ordering.
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 <, and justify the conclusions, e.g., by using a visual fraction model.
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.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.)
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
