How do I help students learn about fractions?
Both parents and teachers write to Teacher2Teacher asking for help in teaching about fractions. One writer put it like this:
"I need as much help as you can give me on fractions. My niece needs help -- big time -- and her parents won't help so Uncle is going to try and help. It's been a long time since I graduated in 1970, so I would love everything you can give me to help. She is a good kid and having a real hard time with this."
Teacher2Teacher Associates and contributors in the Teachers' Lounge discussions have responded to these many letters suggesting a variety of methods. Somewhere in the suggestions will be ideas to help your student learn about fractions.
