My students are currently wrapping up a unit on adding and subtracting fractions with like and unlike denominators. It is essential that fifth graders have a working conceptual understanding of fractions, as well as an ability to practically solve problems that involve operations. By this point, they should be able to extend their ability to model into their ability to solve using algorithm. This week, we will be spending some time working in Thinking Blocks. Thinking Blocks has recently moved to Math Playground, but they also have newly developed apps for fractions, multiplication, division, addition, and subtraction. It integrates modeling, algorithm, and word problems. I am hoping it goes well with my kiddos this week. I’ll let you know.
What other sites do you use for an integrated approach to teaching operations with fractions?
