Kindergarten Fall Math — Counting to 100, Subitizing, Cardinality, Shapes, and Pattern

K
math.gK.f.ps.math_practices
Mathematical practices at K — explain thinking, use tools, model with math
Children develop the habit of explaining HOW they know (CCSS MP.3 at K level), choosing appropriate tools (MP.5: fingers, counters, ten-frame), and modeling real situations mathematically (MP.4: 'How many shoes are at the door if there are 4 children?'). This skill is woven across every lesson, not taught in isolation.

(not yet loaded)
Common misconceptions
- Cannot articulate strategy beyond 'I just knew' (the goal at K is to begin articulation, not master it).
- Reaches for the same tool every time (no flexible tool choice).
- Does not connect a real-world story to a mathematical action (e.g., does not realize 'gave 2 to friend' means subtract).
