Measurement

__ 29/03/2011 __

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

Estimate of how many km per hour in 1 KM: 10KM per hour.

After Test I have discovered that I can run 13.3Km witch was more than I thought.

__30.03.2011__

Time taken 100m= 1. Took me 16 seconds 2. 16 times 10=160 ÷ 60= 2.6 60÷ 2.6= 23KM per hour 60÷ 16= 3.75KM per second Voice thread: Speed media type="custom" key="8902458" How many KM per hour can I run media type="custom" key="8902470"

1. What speed can a student travel by bike Km per hour Our time was 3:05

Estimation __31 KM per hour__ Actual __19.672 KM per hour__ __I went 60÷3.05= 19.672 KM per hour__

2. How many meters per second can a student travel by bike? Our time was 3:05 Estimation __9.5 Meters per second__ Actual __5.405 meters per second__ __I went how many seconds are in 3:05 witch is 185 so I went 1000__ ÷ 185= 5.405 meters per second.

Reflection:

I really liked doing the Km measurement because doing the running and trying to work it out But I am now good at working it out it takes me a while to click, but I am getting there and progressing.
