Number lines are like visual rulers that help us understand numbers and how they relate to each other. When we solve word problems using number lines, we're drawing a picture of the problem! We can use jumps forward to add and jumps backward to subtract. Always start at the first number mentioned in the problem and then jump the correct number of spaces in the right direction. Practice makes perfect! 🤩
