This resource is designed to help students master decimal operations and place value understanding, focusing on performing calculations accurately to the hundredths. It spans five days of structured learning activities, beginning with visualizing decimals using base-ten models, including various representations like flats, rods, and small cubes. Students will engage with strategies for estimation and reasonableness, comparing decimal addition to whole number addition. Error analysis is emphasized through activities like 'The Bug Hunt', where students identify mistakes in decimal calculations, and reinforce concepts with practice problems. The resource culminates in a self-reflection exercise to evaluate their confidence and understanding of decimal skills.
