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 biking 1 km is 3 min (17.1 kmph) Actual : 3.05 min 19.67 kmph

My estimation for biking 1k is 3 min ( 10 mps ) Actual : 3.05 min ( 5.4 mps )


 * Reflection on maths**
 * Measurement**

I now know how to find out the average speed of something. I can also find out the mps and kmph. I am still unsure how to work out kmph and mps with very large numbers. I still need helpful reminding of how to do convert things and figure out the average speed. The F.I.o activity was challenging but I got the hang of it. I really like the book because it really makes my brain think hard and I like when maths is hard like that.
