by Esa Helttula
Apps for traditional algorithms: Long Division, Long Multiplication, Column Addition and Column Subtraction. See Details...
Apps That Use the Algorithms in the Everyday Math Curriculum
|
The Partial Sums Addition app lets the user to solve random addition problems using the partial sums addition method.
In the Everyday Mathematics curriculum the partial sums method is the focus algorithm for addition. |
|
The Everyday Column-Addition app can be used to teach and study the column-addition method.
In the Everyday Mathematics curriculum the column-addition method is one of the algorithms for addition. This is not the same algorithm than the standard column addition.
|
|
The Partial Differences Subtraction app lets the user to solve random subtraction problems using the partial differences subtraction method.
In the Everyday Mathematics curriculum the partial differences method is one of the algorithms for subtraction. |
|
The partial quotients division app helps to teach and study the partial quotients division method with custom and random problems. |
|
The Trade-First Subtraction app lets the user to solve random subtraction problems using the trade-first subtraction method.
In the Everyday Mathematics curriculum the trade-first method is the focus algorithm for subtraction. |
|
Lattice multiplication is algorithmically equivalent to long multiplication. A lattice (a grid) guides the calculation. All the multiplications are done first and then the additions. The method was introduced to Europe in 1202 in Fibonacci's Liber Abaci. |
|
The Partial Products app lets the user to solve random multiplication problems using the partial products method.
In the Everyday Mathematics curriculum the partial products method is the focus algorithm for multiplication. |
|
The Column Division app lets the user to solve random division problems using the column divison method.
In the Everyday Mathematics curriculum the column division method is one of the algorithms for division. |

"The Math apps by idevbooks allow students to practice and reinforce the specific computation strategies taught in class, with as much or as little scaffolding as necessary."
Zachariah R. Prowell:
5th Grade Discovery Teacher / Patrol Leader
Highlands Elementary:
"There are students who see my examples who still need some guidance, and after using your app have said, "Now I get it."
I really look forward to using the other apps you have to offer such as the division and fraction apps. Thank you for recognizing this need and making Everyday Math easier to understand and more fun."
