Ten frame recognition
Ten frame: 1-5 (standard fill)
\[ \text{Top row fill} \]
Work out how many counters are on a ten frame (up to 5).
Ten frame: 1-5 (scattered fill)
\[ \text{Random spots} \]
Work out how many counters when not in usual positions.
Ten frame: 6-10 (standard fill)

Conceptual subitising
Two-group dots: 5 + n
\[ \bullet \bullet \bullet \bullet \bullet \quad \bullet \bullet \]
