Math K-7 IRP Appendix A is divided into 9 sections:

Number (Number Concepts)

Students use numbers to describe quantities. They represent numbers in multiple ways.

It is expected that students will:

Grades K to 1 Grades 2 to 3 Grade 4
Recognize, describe, and use numbers from 0 to 100 in a variety of familiar settings

Develop a number sense for whole numbers from 0 to 1000 and common fractions to tenths

Demonstrate a number sense for whole numbers from 0 to 10 000 and for proper fractions



  • count orally by 1s, 2s, 5s, and 10s to 100

  • estimate and count objects in a set (0 to 50) and compare estimates to the actual number

  • recognize, build, compare, and order sets of objects (0 to 50) using both comparative and numerical terms

  • read number words up to 10

  • explore, represent, and describe numbers up to 50 in a variety of ways

  • use a calculator or computer to explore and represent numbers up to 100

  • demonstrate and explain orally an understanding of "half" as part of a whole


  • estimate and then count an increased number of objects in a set, and compare the estimate with the actual number

  • skip count forward and backward by 2s, 5s, 10s, 25s, and 100s to 1000, using starting points that are multiples; and skip count forward using random starting points

  • recognize, build, compare, and order sets that contain 0 to 1000 elements

  • round numbers to nearest 10 and 100

  • read and write number words to 100 and numerals to 1000

  • use ordinal numbers to 100

  • explore, represent, and describe numbers to 1000 in a variety of ways, including the use of calculators and computers

  • demonstrate place-value concepts concretely and pictorially to give meaning to numbers 0 to 1000

  • demonstrate whether a number is even or odd

  • recognize and explain whether a number is divisible by 2, 5, or 10

  • demonstrate and explain in a variety of ways an understanding of halves, thirds, fourths, fifths, and tenths as part of a region or a set


  • estimate and then count the number of objects in a set (0 to 1000), and compare the estimate with the actual number

  • use skip counting (both forward and backward) to support their understanding of pattern in multiplication and division

  • compare and order numbers up to 10 000

  • read and write number words to 1000

  • round numbers to the nearest 10, 100, and 1000

  • represent and describe numbers to 10 000 in a variety of ways

  • demonstrate concretely, pictorially, and symbolically place-value concepts to give meaning to numbers up to 10 000

  • sort numbers into categories using one or more attributes

  • demonstrate an understanding of hundredths as part of a region or set

  • connect proper fractions to decimal fractions (tenths and hundredths) using manipulatives, diagrams, and symbols


It is expected that students will:

Grade 5 Grade 6 Grade 7
Demonstrate a number sense for whole numbers, from 0 to 100 000, and will explore proper fractions and decimal fractions

Develop a number sense for common fractions and explore number sense for whole numbers

Demonstrate a number sense for decimal fractions and integers (including whole numbers)



  • demonstrate concretely and pictorially an understanding of place value from hundredths

  • read and write numerals to a million

  • read and write number words to 100 000

  • use estimation strategies for quantities up to 100 000

  • recognize, model, and describe multiples, factors, composites, and primes

  • compare and/or order whole numbers

  • represent and describe proper fractions concretely, pictorially, and symbolically

  • demonstrate and describe equivalent fractions

  • compare and order proper and decimal fractions to hundredths


  • read and write numerals greater than a million

  • use estimation strategies for quantities up to a million

  • distinguish relationships among multiples, factors, composites, and primes

  • represent positive powers of numbers concretely, pictorially, and symbolically

  • use power, base, and exponent to represent repeated multiplication

  • explain the meaning of integers by extending their counting to numbers less than 0

  • identify practical applications of integers

  • read and write numbers to thousandths

  • demonstrate and explain the meaning of improper fractions and mixed numbers (positive) concretely and pictorially

  • demonstrate and describe equivalent mixed numbers and improper fractions concretely and pictorially

  • compare and order improper fractions, mixed numbers, and decimal fractions to thousandths

  • demonstrate and explain the meaning of ratio concretely and pictorially

  • demonstrate and explain the meaning of percentage concretely and pictorially


  • recognize, model, identify, and describe common multiples, common factors, least common multiples, greatest common factors, and prime factorization

  • write whole numbers as expanded numerals using powers of 10 and in scientific notation

  • use divisibility rules to determine whether a number is divisible by 2, 3, 4, 5, 6, 8, 9, 10, or 11

  • read and write numbers to any number of decimal places

  • recognize and illustrate that all fractions and mixed numbers can be represented in decimal form (including terminating and repeating decimal fractions)

  • convert from terminating decimal fractions to common fractions and from single-digit repeating decimal numbers to common fractions using patterns

  • demonstrate concretely and pictorially that the sum of opposite integers is 0

  • represent integers in a variety of concrete, pictorial, and symbolic ways

  • compare and order integers
