Graph – True or False

SUGGESTIONS
  individually or in pairs
  time limit
  target number of correct answers
  ask for further sentences but give a focus, eg ‘Write a sentence that is true’,
‘Write one of each and swap with a different pair’
 challenge pupils – who can write the most mathematical sentence about the
graph (works well if this is a starter for a related topic, and pupils can return to
the graph for the plenary to make their ‘mathematical’ sentence even more
complicated)
 give some information, eg ‘There are 3 True sentences’

SOLUTIONS

Goliath and Titan are the same height.                          True

Oblivion is 109 feet high.                                      False 190

The Ultimate is the longest coaster.                            Not Sure not enough info in graph – was true in 2005, longest in the world!

Millenium Force is nearest to 100 yards high.                   True 100 yards = 300 feet

Top Thrill Dragster has the biggest drop, 400 feet.             False 400 not 4000

Steel Dragon is 10 metres higher than Millenium Force.          False 10 feet, not metres

Titan is 50 feet shorter than Steel Dragon.                     True 52 is nearer

Top Thrill Dragster is twice as tall as Oblivion.               False but a good approximation as 400 @ 2 × 190
