We’ve just added new resources to Lumio! In the “More or Less 100ths” learning pathway, students build on their knowledge of comparing decimals to comparing two decimals to hundredths. Learners use shapes models to create and represent decimals that are greater than (>) or less than (<) other decimals. They recognize that comparisons are only valid when they refer to the same whole. Using models and intuitive interaction, students are able to justify their conclusions.
As an extension for learners ready for more challenging problems, we recommend using Compare Decimals in 5th grade. Here learners will compare decimals without models, using their knowledge of place value.
