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

 * calculate speed from measured distance and time
 * solve multiplication problems using doubling and halving strategies
 * use know multiplication facts to solve multiplication problems

__30.03.2011__ estimation 15 km per hour

I can run 1km in 4.00 minutes and 15 km km per hour so I estimated right

media type="custom" key="8902920"

media type="custom" key="8902930" 16 seconds =20 km per hour =6.3 meters per hour

what speed can a student travel by bike Estimate: 20 km Actual: 18.8

how many meters per second can a student travel by bike Estimate 10 mps Actual: 5 mps

Reflection:

I know how to work out how many meters per second I can run and how nicholas many meters per seconds can bike. I found the book work hard
