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 (www.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

What speed can a student travel by bike km per hour? Time: 3.20 Estimation: 13.5 km p/h Actual: 18.75 km per hour. (60 ÷ 3.20)

How many meters per second can a student travel by bike km per second? Time: 3.20 Estimation: Actual: 5.20 m per second. (1000÷192)

Now I know how to work in km p/h and working the out the speed of something. Today the book work was hard and I did not do much of it cause I did not understand it at all!!!
