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 to 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

Estermation 2.5 km and after that test i could run 12km an hour

What speed can a student travel by bike kmph

Estermation 60km Actual18.75km

2. How many meters per seconds can a student travel by bike. Estimation: 10seconds Actual:5.46

this is how i woked it out the first question: I went 60÷3.05= 18.75

This how i woked out the second question: I went 1000÷3.05=327.8÷60=5.46

Reflectin I now know how to work out the how many km I can do in an hour. And I now now how to work out how many seconds per hour i am traveling.
