5th Grade Math – Decimal Place Value

Clip 3/29: Day 1: Decimal Pre-Lesson Part C


Erika Isomura evaluates her students’ understandings in moving from place values in multiplication to using various models to understand decimals.

Some students are moving from fractions to decimal notations. Erika describes her number talks as “priming the well” for subsequent learning. She presents several days’ worth of anchor charts to show how some of her students were starting to make the conceptual shift from fractions to decimals. Erika and Mia Buljan discuss how the students’ thinking connects to a “mentor problem” about cutting up cake.
