## HMH Into Math Grade 3 Module 3 Answer Key Understand Multiplication Strategies

**Entrepreneur**

Entrepreneurs are people who start and run their own businesses. They often start a business to solve a problem. For example, a bike rider may see a need for a better bicycle helmet, which inspires the biker to make improvements to it. Then the biker may start a business to manufacture or sell the improved helmet. You can thank entrepreneurs for improvements to child car seats, umbrellas, and car safety features like air bags.

New businesses started by entrepreneurs are called startups. Did you know that three new startups launch globally every second?

**STEM Task:**

Work with a partner to brainstorm an improvement to an existing product or a new product that meets a need. Your idea could be an improved backpack or better safety equipment for sports. Together, make a list of ideas. Then select your best idea and describe to the class the problem it solves.

**Learning Mindset!**
