Application: Long Multiplication
What it is: With the Long Multiplication app, students can solve random and user inputted multiplication problems using the column multiplication method. Just like the Long Division app, when students enter the correct answer it “flies” to the right place. If the student enters the wrong number the answer will not move. Students can practice long multiplication with up to 5 digits in the upper number, 1 or 2 digits in the lower number, enter a custom problem, hide the current operation for each column, highlight the operands for the current operation, choose from three different color schemes, and change the speed of the animations. Students can choose the position of the regrouping (either above or below the equation) based on the method they are using in your classroom.
How Long Multiplication can enrich learning: What makes the Long Multiplication app so great is the immediate feedback it gives to students. They don’t work through an entire problem before realizing their mistake, but instead can take a closer look and re-solve as they go to come up with the correct answer. The app is very easy to use and has some nice customization options that will appeal to students using it to study. The step by step animation and guidance will help students get the column method of multiplication down in no time. The ability to enter their own numbers means that students can input problems from a math curriculum or text-book and work through the step by step process with any problem. Your reluctant math students will love this app, it will act as their own personal tutor sitting with them and encouraging them on!
