Mathematics
This Grade 7 mathematics worksheet builds fluency with representing and subtracting integers. Students first rewrite subtraction equations as equivalent addition equations, including equations with negative values such as x − 14 = −20. They then solve 10 integer-subtraction problems involving positive and negative numbers, with number lines suggested as a support, and finish by identifying that subtracting is the same as adding the opposite. All 13 items use a multiple-choice format, making the worksheet useful for guided practice, independent review, or a quick formative check. The worksheet is designed for Grade 7 students learning how signs affect integer subtraction, especially when subtracting a negative number. Reviewing the answer choices can help teachers identify whether students understand the operation or are selecting a result based only on magnitude. This free printable worksheet includes a complete answer key for efficient checking and instructional follow-up.

This Grade 7 worksheet focuses on rewriting subtraction equations as equivalent addition equations and solving subtraction problems with positive and negative integers. Its 13 multiple-choice items move from representations such as a − 5 = 11 to calculations such as 5 − (−12), with number-line use suggested for support. The final true-or-false item reinforces the rule that subtracting is the same as adding the opposite.
Begin by modeling how a subtraction equation can be rewritten as addition of the opposite, then use the first two equation-representation items to have students explain why the terms change order. Next, solve selected integer-subtraction items on a number line, emphasizing the direction of movement when the subtracted number is negative. Use the final statement about adding the opposite as a class summary students can justify with one of the worksheet’s examples.
Watch for students reversing the terms incorrectly when rewriting equations, such as choosing an addition equation that does not isolate the original variable. In the calculation items, common errors include treating subtraction of a negative as subtraction of its magnitude, losing the negative sign in answers such as −5 − 12, or choosing a positive result because they compare absolute values only. Ask students to show the equivalent addition step or a number-line move when an answer is incorrect.
Assign the worksheet as a printable PDF or as a digital quiz on Wayground. It includes a complete answer key for checking the 13 multiple-choice responses, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable format also gives schools an option when they want to reduce screen use.
Use the worksheet’s Advanced Settings to adjust font spacing or increase the font size so the integer equations and answer choices are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language while keeping the multiple-choice practice focused on rewriting subtraction as addition and solving signed integer expressions.
