This activity builds students’ awareness of the role played by a unit’s scale or size when working with fractions.
About the Lesson
In this TI-Nspire™ lesson, students investigate how the size of a fraction can vary with the scale used to define the unit fraction. The concept of the whole is critical to developing an understanding of fractions (e.g., foot is larger than inch but smaller than meter). The lesson builds students’ awareness of the role played by a unit’s scale or size when working with fractions. This final lesson of the Fractions series, leads into the concept of ratios and equivalent ratios, but might be used earlier to develop the concept of different sized unit fractions depending on the original scale.
This is Lesson 15 out of 15 in the Building Concepts in Mathematics: Fractions Series.
