When do we operate with fractions? I can think of several scenarios, but the one that I use quite often would be converting recipes to suit the amount of people I want to serve. I used the Kraft Canada website to find some recipes I knew would be great. I needed simple recipes that would appeal to this age group, and also ones that had not too many ingredients, as I wanted to make a QR Code so they could check their answers. (I wrote about how to create QR Codes here.) This site was great for that, and I highly recommend checking it out! (I also used the Hunter Angler Gardener Cook website for a goose jerky recipe, as I thought that may appeal to some students who weren't completely sold on baking.)
So, when the students go to this station, they take a worksheet and convert the ingredients from serving 12 people to serving 8 (for example). Once they have their answers on the worksheet, they use the i-nigma app (it's free!) on the iPad to scan the QR code at the left so they can self-correct. That's it. Independent practice time using a skill they are currently working on, and no extra marking for the teacher. That's what Guided Math is all about - freeing up some teacher time so s/he can work with small groups and differentiate a little more easily. I wrote about Guided Math here if you are interested in reading more about this management option for your Numeracy classroom. I do plan to continue to add more worksheets to this unit, so if you like them, check back again later to grab some more freebies.
