• NS.1.1 The student will
  • NS.1.1.a count forward orally by ones to 110, starting at any number between 0 and 110;
  • NS.1.1.b write the numerals 0 to 110 in sequence and out-of-sequence;
  • NS.1.1.c count backward orally by ones when given any number between 1 and 30; and
  • NS.1.1.d count forward orally by ones, twos, fives, and tens to determine the total number of objects to 110.
• NS.1.2 The student, given up to 110 objects, will
  • NS.1.2.a group a collection into tens and ones and write the corresponding numeral;
  • NS.1.2.b compare two numbers between 0 and 110 represented pictorially or with concrete objects, using the words greater than, less than or equal to; and
  • NS.1.2.c order three or fewer sets from least to greatest and greatest to least.
• NS.1.3 The student, given an ordered set of ten objects and/or pictures, will indicate the ordinal position of each object, first through tenth
