Florida B.E.S.T. MA.6.NSO.4

MA.6.NSO.4 is a B.E.S.T. standard. These are the benchmarks under it.

• MA.6.NSO.4.1

  Apply and extend previous understandings of operations with whole numbers to add and subtract integers with procedural fluency.

• MA.6.NSO.4.2

  Apply and extend previous understandings of operations with whole numbers to multiply and divide integers with procedural fluency.

01

What Students Need to Do

Students calculate with positive and negative whole numbers using all four operations. They explain how signs affect results and connect equations to number lines, counters, or real situations.

02

What Mastery Looks Like

Students accurately add, subtract, multiply, and divide positive and negative integers. They use number lines, counters, or operation rules to explain signs and check whether answers are reasonable.

03

Common Misconceptions

Students may add absolute values and attach a negative sign whenever one number is negative. They may also confuse subtracting a negative with subtracting a positive or apply multiplication sign rules to addition.

04

How to Assess It

Give an exit ticket with three problems: −7 + 12, 4 − (−9), and (−6)(−3). Ask students to solve and explain one answer with a model or rule.

1. 01

   Give pairs red and yellow counters to model zero pairs, then solve integer addition and subtraction problems.

2. 02

   Ask students to explain why 5 − (−3) equals 8 using a number line and a written rule.

3. 03

   Play integer operation bingo using teacher-called expressions and student boards filled with possible answers.

4. 04

   Use gains and losses from a mock bank account to calculate balances after several deposits, purchases, and fees.

• MA.4.NSO.2

  Build an understanding of operations with multi-digit numbers including decimals.

• MA.6.AR.1.4

  Apply the properties of operations to generate equivalent algebraic expressions with integer coefficients.
