This week in Mathematics we started learning about Measurement
Skills we covered: units of measure, starting point, units, true measure, metre ruler and problem solving through team work.
Learning experience: This week one Ninja shared that Kiwi free-diver William Trubridge broke his own free diving world record in the Bahamas. William Trubridge set a new wor;d record free diving to a depth of 124 metres.
In order to put into perspective the length Trubridge dived, students worked in groups using a metre ruler to measure 124 metres.
Students discussed in their group how they were going to work out the length using the metre ruler.
Students then tried measuring 122 metres using the metre ruler
After their task they got back into their groups to discuss what they found worked well, what they found challenging and what they could do better next time.
- They needed a better plan next time before they start
- Team members were good/helpful
- Some team members did not participate fully
- Team work makes work easier
- They could have used something to mark the ground with using a team members finger to mark where the ruler stopped didn't work as when the member moved they loose the mark and had to start again. Some teams restarted 3 times.
- To get a true measure they needed to measure in a straight line
- They were amazed at how long 124 metres measured
- Two groups came close and only got a rough estimation of 124metres because they did not measure in a straight line, deeming it not a true measure.
- Trubridge performed this feat by holding his breath for four minutes and 34 seconds - so we tried holding our breath for this length of time but did not come close to 30 seconds
