Comparing Lengths & Heights
Compare two objects directly by length or height and describe the difference using language such as long, short, tall, longer, shorter, taller, double, half
What a learner can do afterwards
- Stand two children back-to-back and say who is taller/shorter
- Directly compare the heights of two towers and describe one as taller
- Use 'longer' and 'shorter' to compare two ribbons placed side by side
