Measurement

Exploring the concept of speed. Students will realise that speed is made up of two measurements, one of distance travelled, and one of time taken. These two measurements can be used to calculate speed, which can be converted to different units.

L.I. Students will be able to 1. use appropriate scales, devices & metric units for length, area, volume & capacity, weight (mass), temperature, angle and time. 2. convert between metric units, using whole numbers and commonly used decimals. 3. use a range of multiplicative strategies when operating on whole numbers.

S.C. We will (nzmaths.co.nz)
 * calculate speed from measured distance and time
 * solve multiplication problems using doubling and halving strategies
 * use know multiplication facts to solve multiplication problems

My estimation for running km per hour. 14 kmp. After the test I have discovered that I can run 14 kmp.

Time taken over 100m 16 secs 15.1 kmph 6.6 mps

31.3.11 1. What speed can a student travel by bike. estimation 14km real 18.75kmph 2. What speed can a student travel per second. estimation 7mps real 5.2mps

I now know how to measure speeds in km and mps.
