  • create a table or chart from a pattern shown concretely
  • use information in a problem to create a table or chart
  • create a pattern concretely from a table or chart
  • explain why the same pattern exists whether it is shown concretely, in a table, or in a chart
  • use patterns in tables or charts to solve problems
  • use diagrams (Carroll diagrams and Venn diagrams) to sort and organize information and to solve problems
  • describe the patterns and relationships shown in a given Carroll diagram or Venn diagram
  • use a symbol to represent the unknown number in an addition, subtraction, multiplication, or division problem (e.g., 24 ÷ 6 =? 24 = 6 × ? or 24 = 6 × ◊)
  • write an equation with an unknown to represent a given story problem
  • create a story problem for a given equation having one unknown

  • read and write time from a 12-hour analog clock, a 24-hour analog clock, and a 24-hour digital clock
  • describe time as “minutes to” or “minutes after” the hour
  • describe time as a.m. or p.m. and identify activities that occur during the a.m. and/or during the p.m.
  • read and write dates in a variety of forms (e.g., March 21, 2015; 2015/03/21; 21/03/2015; or 21/03/15)
