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 __**


 * 7.5 km per hour**


 * After the test, I have discovered that I can run 14.2 km per hour.**

1. What speed can a student travel by bike> Estimation = 15 km per hour Actual = 19.67 km per hour

2. How many metres per second can a student travel by bike? Estimation = 10 m per second Actual = 5.46 m per second

This is how I worked out the first answer: I went 60 ÷ 3.05 = 19.67 km per hour. (I used a calculator)

This is how I worked out the second answer: I went 1000 ÷ 3.05 = 327.8 ÷ 60 = 5.46 m per second. (I used a calculator)

__Reflection __ I now know how to work out the speed of the km using time and length as Mrs stock has gone through lessons helping us learn it. I am still unsure about working out how to find out the metres in a second, but I still can work it out. I still need help with figuring out if I should use times or divide to figure out the number. The FIO activity was quite challenging but I did start to get the hang of it after a while. Harrison, Morgan and I did well trying to solve the answers to the questions but sometimes we did have to use a calculator to make sure that we were right.
