Understanding Decimals and Division

Natalie Rhodes presents a fifth-grade math lesson on dividing decimals by whole numbers. The lesson includes two main problems: dividing a watermelon into equal parts and determining the spacing of ladder steps. Students learn to convert decimals into tenths for easier division and apply division strategies using visual models.
