Kindergarten Fall Math — Counting to 100, Subitizing, Cardinality, Shapes, and Pattern
Math · AT K math.gK.f.at.patterns_extend

Recognize, extend, and create repeating patterns (AB, AAB, ABB)

Identify the unit of repetition in a repeating pattern (red-blue-red-blue → unit is 'red-blue'). Extend a given pattern by adding 2-4 more terms. Create an original repeating pattern. Translate a pattern across modalities (red-blue beads = clap-stomp body pattern = circle-square shapes).

Common misconceptions
  • Extends pattern by adding only ONE element (red-blue-red-blue, then adds one red — does not see the unit).
  • Treats AAB as ABA (loses repeated-element awareness).
  • Cannot translate a color pattern into a body-movement pattern (does not generalize the unit-of-repetition concept across modality).
  • Adds random elements not matching the unit.

3 Create your own ABB pattern using 3 colors of crayons in your math journal. Draw at least 9 elements (3 full repetitions of the unit). create ABB with crayons
