Mathematical Problem Solving

This lesson covers test-taking strategies in math and science, focusing on calculator-active questions. It includes a practical example of calculating the area of a poster without a heading. The lesson then transitions to using tables and double number lines to understand equivalent ratios and solve distance over time problems. An example involving the International Space Station is used to illustrate these concepts. The importance of labeling and understanding distance over time is emphasized throughout.
