A.   Sort, classify and order objects by size, number and other           properties and describe the attributes used.

B.   Extend sequences of sounds and shapes or simple number   patterns and create and record similar patterns.

1.   Extend simple number patterns (both repeating and growing     patterns), and create similar patterns using different objects,    such as using physical materials or shapes to represent       numerical patterns.

  

C.   Create and extend patterns and describe the rule in words.

1.   Use patterns to make generalizations and predictions; e.g.,            determine a missing element in a pattern.

2.   Create new patterns with consistent rules or       plans, and

      describe the rule or general plan of existing patterns.

  

D.   Model problem situations using objects, pictures, numbers,

      and other symbols.

1.   Use objects, pictures, numbers and other symbols to

      represent a problem situation.

  

E.   Solve open sentences and explain strategies.

1.   Recognize equivalence and extend the concept to situations      involving symbols; e.g., 4+5=9 and 9=4+5 and 4+5=3+6=…

  

F.   Represent an unknown quantity as a variable using a symbol.

1.   Use symbols to represent unknown quantities and identify        values for symbols in an expression or equation using

      addition and subtraction; e.g., _ + 1 = 10, _ -2 = 4.

  

G.  Describe and compare qualitative and quantitative change.

1.   Describe qualitative and quantitative changes, especially

      those involving addition and subtraction; e.g., a student

      growing taller versus a student growing two inches in one year.
