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

1. What speed can a student travel by bike? Estimation - 15km per hour Actual - 19.6km

2. How many metres per second can a student travel by bike? Estimation - 5m per second Actual - 5.4

Reflection I now know who to find out the meters per seconds when walking, biking or running. The F.L.O activity was really tricky and it took quite a long time to figure out. I got a few answers but I don't think they are right.
