Teaching and Group Activities for Understanding
Day 1 Teaching
Show a large stop-clock or a clock with a second hand. This hand takes one minute to move round the clock. How many seconds are in a minute? Wait until the second hand is at the top and count as it moves. Repeat with the clock turned away. Discuss. Children try counting 15 and then 30 seconds in their heads. Then they estimate how many letters they can write in 30 seconds. They write the letters and compare the results to their estimates.
-- Gain an understanding of what can be achieved in 15 and 30 seconds.
Day 2 Teaching
Ask children to perform a physical action, each child in turn, like standing up and sitting down again. How long does it take, to the nearest minute?
Repeat - can it be done inside 1 minute? Remind children how many seconds are in a minute. Help them to get a sense of the length of a minute.
Time for 1 minute to find out how many times the children can do ‘head, shoulders, knees, toes’.
Use the in-depth problem-solving investigation ‘Order, Order!’ from NRICH as today’s group activity.
Or, use these activities:
-- Gain an understanding of what can be achieved in 1 minute.
