During a discussion of data representations, ask students to describe the data without using numbers. This should bring out students’ use of comparative words, such as lighter, thinner, etc.
TEACHER NOTES:
“From a very early age, children recognize examples of change in their environment and describe change in qualitative terms, such as getting taller, colder, darker, or heavier. By measuring and comparing quantities, such as when keeping track of variations in temperature or growth of a classroom plant or pet, children also learn to describe change quantitatively.“12
“In prekindergarten through grade 2, students can, at first, describe qualitative change (‘I grew taller over the summer’) and then quantitative change (‘I grew two inches in the last year’).”13
