This online number bond tool makes practicing addition easy. A number bond shows the addends of a simple sum. For example, the number bonds for 4 are 3 + 1 , 2 + 2 , and 0 + 4. Number bonds also reflect subtraction facts, as the sum minus either addend equals the other addend.
To use this online number bond tool, drag the numerals you want to use onto the bond. Or, use the pencil tool to write the numbers manually. Use the eraser tool to erase drawings and the trash can tool to clear the canvas.
