Measurement

__**29.03.2011**__

Exploring the concept of speed. Students will realize 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 • Calculate speed from measured distance and time • Solve multiplication problems using doubling and halving strategies • Use know multiplication facts to solve multiplication problems

Reflection-measurement

I still don't understand and have no idea about km per hour and seconds per minute and need quite a lot of help doing some of the answers about measurement. When we had to go out and do some running and biking and record the answers after, I had no idea how to record the answers, I had some help from other people but I still didn't get it. I also don't know how to do the book work ether.
