Mathematics

This free printable First Grade Math worksheet helps kindergarten and first-grade students practise basic addition and subtraction through 15 multiple-choice questions. The set includes direct equations such as 14 − 8 and 10 + 6, missing-number equations such as 8 + ___ = 15 and ___ − 1 = 7, and a larger-number addition item, 100 + 100. Students select the correct answer from four choices, building accuracy with fact recall and equation structure. Use this worksheet for independent practice, a quick check of foundational computation, or review after modeling addition and subtraction strategies. The missing-number items encourage students to reason about the relationship between an unknown and the other numbers in an equation, rather than only calculate a presented fact. It is designed for kindergarten to Grade 1 mathematics instruction and includes a complete answer key for efficient checking and feedback.

FAQs

What does this First Grade Math worksheet cover?

This worksheet covers 15 multiple-choice questions on basic addition and subtraction, primarily with numbers through 20. Students solve direct equations such as 17 − 9, identify missing addends or starting numbers in equations such as 8 + ___ = 15 and ___ − 1 = 7, and apply place-value understanding to 100 + 100.

How can I use this worksheet to teach addition and subtraction equations?

Model one direct fact, such as 10 + 6, and have students explain how they found the answer before introducing the missing-number items. Then use equations such as ___ + 9 = 17 to discuss the unknown as a number that completes the total, and invite students to check their choice by substituting it back into the equation.

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

Students may choose a nearby answer when subtracting, confuse the operation symbol, or treat the blank in 8 + ___ = 15 as the answer to the entire equation rather than the missing addend. They may also reverse the meaning of ___ − 1 = 7 and select 6 or 7 instead of finding the starting number, or overlook that 100 + 100 equals 200.

How do I assign and grade this First Grade Math worksheet?

Wayground provides this worksheet as a printable PDF and as a digital quiz, and it includes a complete answer key for all 15 multiple-choice questions. You can grade printable student submissions by scanning their work with the Wayground for Teachers app, or review responses in the digital version.

How can I differentiate this addition and subtraction worksheet for my students?

Under the worksheet’s Advanced Settings, adjust font spacing or choose a larger font size so the equations and answer choices are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when that better supports students working with the addition, subtraction, and missing-number items.
