The Common Core State Standards teach students the algorithm for multi-digit addition and subtraction in 4th grade. But some experts say it should be taught sooner.

Math can’t catch a break. These days, people on both ends of the political spectrum are lining up to deride the Common Core standards, a set of guidelines for K-12 education in reading and ...

Consider the standard algorithm for multidigit addition and subtraction, which makes its appearance in Grade 4 of the Common Core math standards.

Thus, our execution of the standard algorithm to compute 25 × 63 requires four small multiplications and some additions. What about the distributive approach? 25 × 63 = 25 × (60 + 3) = 25 × 60 + 25 × ...

This study analyzed children's use of mental computation strategies and the standard algorithm on multi-digit subtractions. Fifty-eight Flemish 4th graders of varying mathematical achievement level ...

The following are three examples of calculation strategies students might discover on their own if they were taught standard algorithms first and allowed to master them before moving on. Common Core ...

The Common Core math standards are a topic of hot controversy, especially on the right. The Daily Signal, a news and commentary site started by the Heritage Foundation, recently featured this ...
