Counting and Cardinality Foundations

Object matching and count meaning become symbols, sequence, count-on strategies, skip-counting, and part-whole readiness.

01One-to-one entry

Match one count word to one visible object.

One to One to 10
02Count meaning to 20

Use the final count as the total and hold quantity across simple representations.

Cardinality to 20One to One to 20Ten Frame Fill and Read
03Symbols and sequence

Connect counted sets with numerals, positions, and the number word sequence.

Read Write Numerals to 20Ordinal Position BasicSequence to 100
04Counting strategies

Start from a known number and move forward or backward without recounting from one.

Count On from NumberCount Back from Number
05Part-whole readiness

Break and rebuild totals before formal addition and subtraction.

Compose Decompose to 10
06Skip-count readiness

Use equal steps as the bridge into repeated addition, multiplication, division, and parity.
