Florida B.E.S.T. MA.5.NSO.2

MA.5.NSO.2 is a B.E.S.T. standard. These are the benchmarks under it.

• MA.5.NSO.2.1

  Multiply multi-digit whole numbers including using a standard algorithm with procedural fluency.

• MA.5.NSO.2.2

  Divide multi-digit whole numbers, up to five digits by two digits, including using a standard algorithm with procedural fluency. Represent remainders as fractio...

• MA.5.NSO.2.3

  Add and subtract multi-digit numbers with decimals to the thousandths, including using a standard algorithm with procedural fluency.

• MA.5.NSO.2.4

  Explore the multiplication and division of multi-digit numbers with decimals to the hundredths using estimation, rounding and place value.

• MA.5.NSO.2.5

  Multiply and divide a multi-digit number with decimals to the tenths by one-tenth and one-hundredth with procedural reliability.

01

What Students Need to Do

Students add, subtract, multiply, and divide multi-digit whole numbers and decimals using place value and reliable written methods. They estimate, interpret remainders, and check whether answers make sense.

02

What Mastery Looks Like

A student computes accurately with whole numbers and decimals, showing regrouping, partial products, and quotient steps clearly. They estimate first and use inverse operations to check their work.

03

Common Misconceptions

Students often line up digits instead of decimal points when adding or subtracting. In multiplication, they may misalign partial products. In division, they may place quotient digits incorrectly or leave a remainder larger than the divisor.

How to Assess It

Give this exit ticket: solve 48.306 + 7.958, 60.000 − 27.684, 326 × 47, and 8,736 ÷ 24. Circle one answer and show how you checked it.

1. 01

   Use place-value disks to model 2,346 + 1,785 and 4,002 − 1,678, then connect each trade to the written algorithm.

2. 02

   Ask students to solve 3,216 ÷ 24, then write why multiplying the quotient by 24 checks the result.

3. 03

   Run a card sort where students match multi-digit computation cards with estimates, exact answers, and explanations of errors.

4. 04

   Give students a school-supply budget, item quantities, and prices, then have them calculate total costs, change, and equal shares.

• MA.7.NSO.2

  Add, subtract, multiply and divide rational numbers.

• MA.3.NSO.2

  Add and subtract multi-digit whole numbers. Build an understanding of multiplication and division operations.

• MA.2.NSO.2

  Add and subtract two- and three-digit whole numbers.

• MA.6.NSO.2

  Add, subtract, multiply and divide positive rational numbers.
