Lesson

5th Grade Math – Decimal Place Value

Clip 4/29: Day 1 Pre-Lesson Part D

Overview

Erika Isomura and Mia Buljan summarize what Erika’s students understood about fractions and decimals prior to the two documented lessons.

Erika notes that her students understood the relationship between fractions and decimals, but did not yet understand the patterns of factors of 10 within decimals. She tested her students’ understanding by having them divide a 3 instead of a 1.

Mia and Erika describe the dilemmas of helping students understand and articulate degrees of smallness.
