All about Number Lines
A number line is a straight line marked with numbers in order. Numbers get bigger as you move to the right and smaller as you move to the left. Number lines help you see how numbers compare and how far apart they are.
To solve 4 + 3, start at 4 and move 3 steps to the right to reach 7.
