Thanks so much for joining in about ...Hi Juliette,<br /><br />Thanks so much for joining in about cooking! I completely left that out and it's such an important aspect of teaching fractions. We are constantly doubling or halving recipes. It prepares them for adding, subtracting, multiplying and dividing fractions. Plus it's good to teach ratios (and science!).<br /><br />Do your fraction circles have knobs? Our youngest has been using our big ones since she was about 1 or 2 yrs old and loves stacking them to make cakes (and sell them in her pretend store) and inevitably creates equivalent fractions. I like the knobbed ones like the Montessori fraction circles but then you can't stack them for equivalent fractions. Having both would be a luxury!<br /><br />I was bummed that our closest teacher store didn't have what I needed. <br /><br />Love your 'snafu' :)Bamboohttps://www.blogger.com/profile/15994594297936498029noreply@blogger.comtag:blogger.com,1999:blog-5588932453570504602.post-2511726025619518992011-02-02T20:17:52.311-08:002011-02-02T20:17:52.311-08:00Hi Beth, for the fractions, and converting etc, I ...Hi Beth, for the fractions, and converting etc, I head for the kitchen! I halve, double, or triple recipes on a regular basis, sometimes just to get my kids 'thinking in fractions'. I'm a big one for saying things like "the recipe calls for 1 1/3 c of flour, but we are doubling it, so we need....? hopefully they answer 'we need 2 2/3 cups of flour'...that's when I pull out the 'snafu' and say 'but I only have a 1/3 measuring cup clean. How many scoops will we need with the 1/3 cup to get 2 2/3 cups?"<br />For fractions without common denominators, I found wooden fraction circles that went up to 12ths and just let my kids play with them (sort of like the knobbed cylinders) and they naturally came up with relationships between the various fractions. Later, when we had to do a more abstract version, they just 'got it' ad if they had trouble, I just got out the fraction circles. If I can find the company I got them from, I will post it....Juliettehttps://www.blogger.com/profile/06444304193765916699noreply@blogger.comtag:blogger.com,1999:blog-5588932453570504602.post-21998513142089722212011-01-27T18:33:38.027-08:002011-01-27T18:33:38.027-08:00Hi Melissa,
Thanks for your comment and encourage...Hi Melissa,<br /><br />Thanks for your comment and encouragement! Just off the top of my head: I would make the whole number 2 using fraction circles of 1/3; so 2 circles made of thirds. Since I only have 1 set of fraction circles personally I would just print out some 1/3 circle fractions on colored paper or cardstock for the demo (matching my thirds if possible). Then next to it I would also form the 2/3 with the fraction circles. I would write 2-2/3 and then I would count out how many thirds and write 8/3. Does that make sense?<br /><br />A more abstract way (after the above) would be to look at the relationship between the 6, 2, and 3 of the six more you added, the 2 wholes, and the 3 pieces. What I'm getting at is that 3 pieces each times 2 wholes will give the number to add to the numerator.<br /><br />For the reverse it's just a matter of getting the pieces (8 thirds) and seeing how many wholes can be made with it and writing it as a mixed number.<br /><br />I'll try to look up the official R and D presentations in my manual and see if I'm even close, lol! That's what I would do, though.<br /><br />Here is a template to print on colored paper/cardstock:<br />http://www.mathatube.com/files/Fraction-Circles-Blank.pdfBamboohttps://www.blogger.com/profile/15994594297936498029noreply@blogger.comtag:blogger.com,1999:blog-5588932453570504602.post-47211041399736978812011-01-27T10:11:52.669-08:002011-01-27T10:11:52.669-08:00hi, I am really enjoying your blog!
I was wonderi...hi, I am really enjoying your blog!<br />I was wondering if you could give me a hand on explaining/showing the concept of turning 2 and 2/3s into a fraction (and vice versa) <br />as well as explaing how to add or subtract fractions that dont have common denomenators.<br />Id appreciate either a link or an explanation, thanks!<br />actually, I can take these questions to the list Playschool6 if you prefer!<br />thanks again,melissamelissahttps://www.blogger.com/profile/12301812362886134294noreply@blogger.com
