Ladder and Watermelon Problem Solving

Natalie Rhodes presents a fifth-grade math lesson focused on dividing decimals by whole numbers. The lesson includes solving two main problems: dividing a watermelon into equal parts and determining the spacing of ladder steps. Students are encouraged to use visual models and base 10 blocks to understand the division process. The lesson emphasizes the importance of place value and mathematical strategies in solving division problems.
