2 - Watch and Notice ~9 mins

Watch as the teacher shows each start and finish pair on the board. We count on from the start hand to the finish hand to see how much time has passed.

Some finish times land on a whole hour, and some land on a half past or a quarter past. Notice how far the minute hand has moved on each one.

👇 Mark your steps as done as you complete them.

Key point

Today we count on from the start hand to the finish hand and say how long has passed.

4 o'clock → 5 o'clock
2 o'clock → half past 2
9 o'clock → quarter past 9
12 o'clock → half past 12

Count on from start to finish
