Equivalent Fractions Anybody?

I'm looking for some different ideas for teaching equivalent fractions to my fourth graders. What would you suggest?

I'm not sure what you've been doing to teach equivalent fractions. My favorite resources are Marilyn Burns fraction units.
I have a class set of plastic fractions bars (35) and we use them to play some Marilyn Burns games. Games like "Cover" and "Uncover" have really helped my students see and understand fractions.

I've been working on a PowerPoint to use with my kids. I haven't tried it with them yet. You will need one Hershey candy bar per two kids. I will try to attach it. I took out the Hershey graphics because I got them off the internet and am not sure if it was okay to keep them in a ppt I was posting. I am thinking of adding some tasks where kids have to divide their half into a different amount of equal parts than their partner does.

I haven't tried attaching anything before, so I hope this works!

My file is a .pptx. Not sure why there is an x at the end unless it's the version of ppt that I have. It looks like I can only post if it is a ppt. Let me know what I'm doing wrong of the .pptx is not the problem. Sorry!!!

Love these games, which are mentioned above. The more that students play with concrete materials the better. You make a whole bar and than fractions for whatever you want of that whole. Its great for discussion around adding and subtracting, equivalent fractions, even multiplying and dividing fractions.

Do you have to buy the Marilyn Burns things?

The resources are a great to buy and have. However, the games are easy.

What you need is different construction paper (all different colours) cut in strips. Depending on how many fractions you want in your kit then that is as many colours as you need. I normally do, whole, 1/2, 1/4, 1/8, 1/16 (for fours), and I add 1/3, 1/6, 1/9 for fives.

Cover-up: students have to roll a dice (I assign fractions to the dice number) students take the fraction they rolled and put it on the whole. They have to roll exactly the number needed to cover up the whole.

Un-Cover: Students start with their whole piece and cover it with two wholes. They then roll the dice and can do three things:

1) nothing

2) uncover the piece they rolled

3) trade in the fractions they have on the whole for equivalent

an interesting discussion that we have after this is if I rolled a 1/2 can I also take off two 1/4 pieces? or really any equivalent parts

Another game that I like to do for mini-lessons is how many more do I need to get to 1/2 or a whole. Great discussion and you have addition and subtraction of fractions.

I use fraction strips for all of my lessons they help students in so many ways.
Anyways hope you enjoy.

I shared these with my kiddos....they liked doing it. I like using fraction bars too, it's a nice visual aid for students.

Strips of equal sized paper folded with 1/2, 1/4, 1/8, 1/16, 1/32. This is an easy and yet manipulative way for the child to see how they are equal.

a few weeks ago and someone gave me this website :

I did the first lesson for an observation and my AP raved about the level of student involvement and thinking I was able to achieve.
