Which activity would be appropriate for integrating multiplication into a second-grade science curriculum?

• A. Calculating how much food the class pet will need for the week
• B. Measuring the length of the pet's cage
• C. Recording weather data for the week
• D. Building a model of the solar system

Answer: (A)

Using multiplication to find totals over time in a science context. This activity shows how multiplying a daily amount by the number of days helps you plan for a week, turning a real-world scenario into a math problem. For example, if the class pet eats 2 cups of food each day, 2 × 7 equals 14 cups for the week. This makes the usefulness of multiplication clear and concrete in a science setting. Measuring the length of the pet's cage focuses on units and measurement techniques, not on combining equal groups. Recording weather data for the week centers on collecting information and looking for patterns, rather than calculating a total using repeated addition. Building a model of the solar system involves modeling and spatial reasoning, with multiplication not being the primary skill needed.
