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 tow 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 7km per hour

After the test I discovered that I can run 13.9km per hour

Time Taken for 100m = 15 seconds

1. I ran 2.4 meters per second 2. My speed was 25km per hour

1. What speed can a student travel by bike?

Estimation: 3:00 Actual: 3:05 Speed: 17 km per hour

2. How many meters per second can a student travel by bike?

Estimation: 3.50m Actual: 5.3 mps


 * Today's Lesson:**

I now know that when working out how fast the speed is, you have to divide the speed you were travlling at by 60 seen there are 60 minutes in an hour.

I still need help with how many meters per second.

The F.I.O activity was a bit harder then the usual math books we get. I got up to number 3.A and struggled on that question.
