Mathematics — Comparing Measurements Beanstalk height-ordering puzzle

Learning objectives

Identify taller and shorter examples
Explain why a common base/reference makes height comparisons fair

Concepts and principles

Height is a vertical distance measured in a consistent unit.
Comparisons can be misleading if pictures are tilted or use different baselines.

Examples and worked solutions

Separate teaching example (not verified as a native game question): Which is taller: a 130 cm stalk or a 1.4 m stalk?: Worked solution: 1.4 m = 140 cm, so the second stalk is 10 cm taller.

Guided practice

Look for any displayed scale marks before dragging a stalk
Compare heights from the same baseline and arrange in the required direction
Check the answer and identify adjacent pairs that were reversed

Expected observations and explanations

Ordering needs a common measurement reference; apparent size alone can mislead.

Assessment questions and answers

What is ascending order for 80 cm, 120 cm and 100 cm?: Answer: 80 cm, 100 cm, 120 cm.
How many centimetres are in 1 metre?: Answer: 100 cm.
