Solving addition word problems using number lines is a fantastic way to visualize and understand how numbers combine. A number line is simply a line with numbers placed at equal distances. To solve an addition problem, start at the first number on the number line and then 'jump' to the right the number of times indicated by the second number. The number you land on is the answer! This method makes addition feel more like a game and less like a chore. 😄
For example, if the problem is 3 + 2, start at 3 on the number line and make two jumps to the right. You'll land on 5, which is the answer.
