Compare Fractions with the Same Denominator

How the lesson starts: Compare Fractions with the Same Denominator

1. Robot charging station

   Hi friend! Welcome to the robot factory! Robots Bolt and Zip are charging up. Bolt's battery is 3/8 full. Zip's battery is 5/8 full. Who has more power?

2. Same size parts

   Both batteries have 8 equal parts, so the parts are the same size. Bolt has 3 parts. Zip has 5 parts. 5 parts is more than 3 parts, so 5/8 is greater!

3. Let's compare 2/6 and 5/6

   Which is greater: 2/6 or 5/6? Both batteries are the same size. Both have 6 on the bottom, so the parts are the same size. 5 parts is more than 2 parts. So 5/6 is greater!
