Ready to explore number lines while adding and subtracting decimals? Start by finding the first number in each problem and mark it with a dot. Then check the second number to see how far to travel. Move forward for addition and backward for subtraction. Mark your destination with another dot and draw a dashed line to show your journey. For extra fun, two number lines have missing labels, and three are completely blank for you to fill in. Now, grab your pencil and let's dive in!
