Measurement

__Tuesday 29 March 2011__

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

L.I. We are learning to use appropriate scales, devices and metric units for length of time.

My estimation for running km per hour was 15km per hour.

After the test I have discovered that I can run 15km per hour. Which was what I estimation was correct.

L.I. We are learning to use appropriate scales, devices and metric units for length of time.

1 How many km per hour I can run. 27km per hour. Way you work it out. 14x10=140÷60=2.20. 2.20÷60=27km per hour

2. How many meters per second can I run.=7.1 meters per second Way you work it out. 100÷14=7.1 meters per second.

1. What speed can a student travel by bike km per hour? Estimation: 32km per hour. Actual: 19.67km per hour.

2. How many meters per second can a student travel by bike Estimation: 11 meters per second. Actual: 5.4 meters per second.

1. The way I worked it out was 60÷3.05=19.67km per hour. 2. The way I worked it out was we worked out how many second in 3.05 which is 185 seconds, then you go 185÷1000=5.4 meters per second.
