About this app
Addition Chalkboard helps students understand addition and memorize the sums of single-digit numbers. The focus is on learning. Addition Chalkboard does not include stressful elements like a countdown clock or high scores. Students can begin with the first column of the addition table, adding 1 to various numbers, and include more columns as they improve. Addition Chalkboard emphasizes drawing numbers correctly and legibly, and works well with the Apple Pencil or other touchscreen styluses. Covers 0 + 0 through 10 + 10.
