Computation

 

Grades K-2 Benchmark: Add and subtract with 2-digit numbers with and without regrouping.

 

Grade 1:  By the end of grade 1, students will develop strategies for addition and subtraction that will lead to future algorithms.  (See Grade Level Indicators No. 16 & 17 of Number, Number Sense, and Operations Standard in the Ohio Department of Education Academic Content Standards for K-12 Mathematics for more details on these strategies.)

 

Grade 2:  By the end of grade 2, students will add and subtract using 2-digit numbers with and without regrouping.

 

Grades 3-4 Benchmark: Analyze and solve multi-step problems involving addition, subtraction, multiplication, and division using whole numbers.

 

Grade 3:  By the end of grade 3, students will add and subtract using 2 or more numbers with and without regrouping; and multiply and divide 2- and 3- digit numbers with a 1-digit factor/divisor.

 

Grade 4:  By the end of grade 4, students will demonstrate fluency with adding and subtracting of whole numbers.

 

  By the end of grade 4, students will multiply and divide whole numbers by 1-and 2-digit divisors and multiples of 10.

 

Grades 5-6 Benchmark: Use and analyze the steps in standard and non-standard algorithmsfor computing with fractions, decimals, and integers; Use a variety of strategies to estimate, compute, solve, and explain solutions to problems involving integers, fractions, decimals, and percents. 

 

Grade 5:  By the end of grade 5, students will estimate the results of computation involving whole numbers, fractions, and decimals using a variety of strategies.

 

Grade 6:  By the end of grade 6, students will develop and analyze algorithms for computing decimals and fractions and demonstrate fluency in their use.  Students must be able to perform fraction and decimal computations and justify their solutions.  Students need to be able to find percents of a number and to compare, order and convert among fractions, decimals, and percents.
