Understanding Fractions and Decimals

Mrs. Lamorn introduces fifth graders to unit five, focusing on place value patterns and decimal operations. The lesson explores the concept of thousandths, using tiles to estimate fractions and understand decimal representations. Students learn to represent fractions on number lines and grids, and how to write decimals for thousandths. The lesson concludes with a reflection on the learning objectives.
