🧠 Use logic to quickly compare fractions

🤔 Relying on algorithms might get you to the right answer, but it robs you of a chance to use your reasoning abilities!

If you asked me two years ago to compare 3/7 and 7/12, I probably would have jumped straight to multiplying, but I love that there’s another way!

🌟 I’ll admit, benchmark fractions don’t always work. For example, try using them to compare 7/12 and 8/15. It fails miserably! We need a more sophisticated method to solve that problem, and our kids will learn about that in fifth grade (at least here in California). 

💡But learning to think about the general size of a fraction is a skill that will be useful to our kids throughout their lives!
