Partial Differences Subtraction helps students learn and practice the partial differences subtraction method step by step.
The app gives students a visual way to subtract numbers by working with each place value separately. The partial differences are then combined to find the final answer.
Students can solve randomly generated problems or enter their own subtraction problems. The number of digits can be adjusted for different skill levels.
The Partial Differences Method:
In the partial differences method, each place value is subtracted separately from left to right. For example, in 936 − 580, the partial differences are 400, −50, and 6. These are then combined to get the final answer: 356.
Teacher endorsement:
“The math apps by Esa Helttula allow students to practice and reinforce the specific computation strategies taught in class, with as much or as little scaffolding as necessary. They also provide individualized feedback to each student, with an immediacy that is not always possible through pencil and paper practice.”
— R. Zeni, Ecole Sandy Hill Elementary, Abbotsford, BC, Canada
Easy to Use:
The numbers are aligned automatically so students can focus on solving each column. After the student solves the operation for each column, the correct answer moves into the right place. If the student presses the wrong button, the answer appears above the keyboard but does not move.
Features:
- Step-by-step partial differences subtraction practice
- Each number can have 2–3 digits
- Randomly generated or manually entered problems
- Current operation for each column can be hidden
- Operands of the current operation can be highlighted
- Customizable interface colors
- Adjustable animation speed
