Practice addition and subtraction with a large number keypad and a worksheet area. Supports a carryover scratch area for addition and an easy number cross out area for subtraction. Special features to accommodate challenges with inaccuracy in pressing keys due to hand movement and coordination challenges. Best user experience is on iPads due to larger display area compared iPhones.
Features:
-Adjustable key repetition delay to help prevent accidental number presses, especially for kids with ataxia or other medical conditions that affect the accuracy in pressing keys
-App designed to accommodate number presses that normally may not register due to key pressing anomalies from ataxia or other hand movement challenges
-Show/hide placement value labels (thousands, hundreds etc.)
-Show/hide thousands column
-Answer check button to verify answers
-Automatically advances the cursor to next cell while typing number to provide a natural typing experience
-Scratch area for addition carryovers and subtraction borrowing
-Cross out numbers in subtraction
-When a cell is selected, only applicable keys for that cell are enabled; other keys are grayed out to make it easier
This was made for my son who needed a large display area for numbers and at times has challenges with hand stability in pressing keys. You can turn off the hand stability accommodation in settings under key repeat if you wish. I hope others find it useful as well. Please send comments to MathMadeEZ@zoho.com
