We present a case study of teaching and learning fraction addition on number lines in one 6th-grade classroom that used the Connected Mathematics Project Bits and Pieces II materials. Our main ...

Many children never master fractions. When asked whether 12/13 + 7/8 was closest to 1, 2, 19, or 21, only 24% of a nationally representative sample of more than 20,000 US 8th graders answered ...

Adding and subtracting algebraic fractions is a similar process to adding and subtracting normal fractions. The denominators of each fraction are different, \(3t\) and \(7t\), so a common denominator ...

Math teachers know that fractions can be hard for the average third-grader. Teachers at a public school in San Bruno, Calif., just south of San Francisco, are trying something new. They're teaching ...

Recent research finds that a solid grade school knowledge of fractions and long-form division accurately predicts later success in high school math. Christie Nicholson reports What part of math was ...

It is less straightforward to picture the answer to this addition because the denominators (bottom numbers) are different. You can only add and subtract fractions when the bottom numbers, or ...
