After a warm up of buzz, I used the abacus to revisit 10 and...... (teen facts) as the teacher had explained that the children were quite confident with these facts. We then compared some teen numbers and ty numbers and what they look like on the abacus ie 12 & 20, 13 &30, 14 & 40, 15 & 50.

Jets making connections between finger patterns and sets of objects
10 fingers is the same as 10 bears
7 fingers is the same as 7 beans
3 fingers is the same as 3 dice

Then moving onto
8 fingers is the same as 8 bears is the same as 8 counters on a tens frame
