Adding Positive and Negative Numbers

10 questions

7th - 7th Grade

Mathematics

This Grade 7 mathematics worksheet helps students add positive and negative numbers in real-world and numerical contexts. Students identify situations with a net sum of zero, recognize additive inverses, and determine whether number sentences produce positive or negative results. The practice includes integers, decimals, and fractions, including examples such as -14 + (-23), 75 + (-14), and -4/5 + 1/5. The free printable worksheet contains 10 questions: 6 multiple-choice items and 4 multiple-select items. Students apply sign rules, distinguish when adding a negative number results in subtraction, and calculate sums with like and unlike signs. It is designed for Grade 7 pre-algebra instruction, independent practice, or a quick check of understanding, and it includes a complete answer key for efficient review and grading.

FAQs

What does the Adding Positive and Negative Numbers worksheet cover?

This Grade 7 worksheet uses 6 multiple-choice and 4 multiple-select questions to develop fluency with sums involving positive and negative integers, decimals, and fractions. Students identify net sums of zero and additive inverses, predict whether sums are positive or negative, decide whether adding a negative number is represented by addition or subtraction, and solve expressions such as -14 + (-23), 75 + (-14), and -4/5 + 1/5.

How can I use this worksheet to teach adding positive and negative numbers?

Begin with the real-world situations about withdrawing money, balancing gains and losses, and returning what is owed to connect net sum zero with additive inverses. Then have students justify their choices in the multiple-select items before solving the numerical expressions, asking them to compare the signs and magnitudes of the terms. Use the final computation questions to model why adding two negative numbers gives -37, while 75 + (-14) gives 61.

What mistakes should I watch for when students complete this worksheet?

Students may select situations that do not net to zero, such as spending twice as much money as they make, or confuse additive inverses with numbers that simply have the same sign. Watch for sign errors when comparing the magnitude of positive and negative terms, especially in -70 + 100 and -14 + (-23), and for treating -4/5 + 1/5 as positive. In the operation questions, students may also overlook that adding a negative number can be evaluated as subtraction when the signs are unlike.

How do I assign and grade this worksheet?

On Wayground, assign Adding Positive and Negative Numbers as a printable PDF or as a digital quiz, and use its complete answer key to review the 10 multiple-choice and multiple-select responses. Printable submissions can be graded by scanning student work with the Wayground for Teachers app.

How can I differentiate this positive and negative numbers worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the integer, decimal, and fraction expressions are easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language while preserving its multiple-choice and multiple-select format.
