Adding and Subtracting Integers Numberline is a Grade 9 mathematics worksheet that builds number-line fluency for integer addition and subtraction. Students answer 10 multiple-choice questions about where to start, which direction to move, and how to evaluate expressions such as -4 + 3, -3 - 2, 5 - 8, and -4 + (-5). The items connect number-line movement to the signs and values in each expression, including adding positive and negative integers and subtracting across zero. This free printable worksheet is useful for introducing or reinforcing the process of solving integer operations visually before students move to less-supported computation. It helps teachers check whether students can identify the starting number, distinguish addition from subtraction movement, and select the resulting integer from plausible answer choices. A complete answer key is included for efficient review, independent practice, or formative assessment.

This Grade 9 worksheet uses 10 multiple-choice questions to teach students how to add and subtract integers on a number line. Students identify the starting number, choose the correct movement direction, and solve expressions such as -4 + 3, -3 - 2, 5 - 8, and -4 + (-5).
Begin by modeling how the first number determines the starting point and how the operation and second number determine the movement. Then use the direction questions in this worksheet to establish that addition moves right for positive values and subtraction moves left, before having students apply the process to the signed expressions. Ask students to explain the movement they used for items such as -4 + (-5), not just select an answer.
Watch for students starting at the second number instead of the first, especially in items such as 8 - 3 and 18 + 6. Students may also reverse the direction for addition and subtraction, ignore the negative sign in expressions such as -3 - 2, or choose a positive result when movement crosses zero, as in 5 - 8 and -4 + (-5).
The worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key. You can grade printable submissions by scanning student work with the Wayground for Teachers app. The printable format also supports schools that want to reduce screen time while preserving structured practice.
Use the worksheet’s Advanced Settings to adjust font spacing and font size so the number-line directions and multiple-choice options are easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language, depending on your students’ needs.
