SCALE (Practise online)Practise online
Have a look at your model car Is it larger or smaller than the real thing? LARGERSMALLER
Sorry Try again BACK
Well done! Now look at your measurements. The scale is 1:18. If the real car is bigger, should you multiply or divide your measurements by 18? MULTIPLYDIVIDE
Sorry Try again BACK
That’s right! Your measurements are in centimetres (cm), but you must change them to millimetres (mm). How many millimetres are there in a centimetre? 10010
Sorry Try again BACK
Almost there! Since 1 cm is 10 mm, multiply your measurements by 10 to change them to mm. NEXT
Now it’s time to compare your measurements to the real thing. Pick your team PORSCHEMERCEDESTOYOTA
Measuring Length Changing centimetres to metres..
Which operation should be done first? x 2.
Metric Units of Length millimetres centimetres decimetres metres.
© T Madas. The metric unit of length is the metre [ m ] Smaller units are the: ( centimetre) cm ( millimetre ) mm ( micrometre ) μmμm ( nanometre ) nm.
Awesome Answer! Sorry. Try again.
RATIOS OF SCALE DRAWINGS. SCALE DRAWINGS SCALE DRAWINGS: A scale drawing is a drawing that represents a real object. The scale of the drawing is the ratio.
Mrs. Planavsky 4 th grade. You’ll be able to change large units of measure to small units of measure to compare the lengths of two items. Objective:
Measurements. Metric measurement is the tool used in science. Because of its ability to measure very small, microscopic samples, the metric units afford.
