Manipulatives-Where Do You Put Them?

Algebra and Functions (Classification and Patterning Strand)

This strand concerns the development of algebraic thinking and reasoning. Included in this strand is the ability to sort, group, an classify objects by some attribute and to recognize, extend, and create patterns.

Understanding Sorting and Classifying In order to sort, we must be able to identify attributes.  Sorting requires deciding how things are alike and how they are different.  When we sort, we decide which things go together and why.  We can sort and resort one set of objects according to different attributes.  We label sets according to the property we used to sort. 
