Easy algebra problems are one-step equations and missing-number problems with small numbers, where the procedure is clear and the arithmetic stays simple, such as n + 5 = 12 or 4 × __ = 20. This generator writes them for warm-ups and confidence building in 5th-8th grade, with an answer key.
On this page, easy means coefficients from 1 to 5, answers from 1 to 20, and one step only, with no combining like terms or distribution. Missing-number problems (__ − 8 = 6, answer 14) link arithmetic students know to equations. Simple algebra problems add two-step equations; basic algebra problems add vocabulary and expressions.
Ask for any of these supports:
A worked example as item 1
A 'check your answer' step: substitute the solution back in
Story-form problems, such as 'Ben has some marbles. He gets 5 more and now has 12.'
On the second or third day of equations, as a warm-up before harder work, or after a rough quiz when a student needs a few correct answers in a row. Move up to simple algebra problems next.
The topic and the format, such as two-step equations or fraction word problems about cooking.
Grade, difficulty, and number of problems. It usually takes 10 to 20 seconds.
Work a few problems yourself, then print the student copy and the answer key.
Teachers across subjects, from AP history to astrophysics, on grading with GradeWithAI.
“I've really enjoyed using the GradeWithAI program. It saves me a ton of time, especially when I have class sizes of 35 or 36 students times five.”

“GradeWithAI doesn't just grade. It gives the student reasoning as to why every point is awarded or not awarded. That is a very valuable thing for the students.”

“More impressive though is that it corrects student answers not simply using a pre-written answer, but by following the thought process they've pursued.”

“For Chadwick users, GradeWithAI has improved feedback efficiency and effectiveness, as it is grounded in existing platforms and is highly adaptable.”

“GradeWithAI [provides] students with timely individualized feedback on their homework assignments and formative assessments. This is a job that is virtually impossible for a teacher to do on a regular basis.”

“Students have also appreciated the consistency and immediacy of the feedback I can provide through GradeWithAI. This has enabled them to make necessary corrections and achieve their desired scores on any assignment.”

GradeWithAI reads handwritten math from scans or phone photos and gives partial credit under your rubric or answer key. You review each score before it posts.

Yes. Ask for 'make item 1 a worked example' and the first item shows a solved equation as a model before the practice items.
One-step equations are a 6th grade standard (6.EE.B.7), and missing-number problems appear as early as 1st grade (1.OA.D.8). Easy sets suit 5th-7th graders meeting equations for the first time and older students who need a confidence reset.
Addition, subtraction, multiplication, division (including long division), fractions, decimals, ratios, percents, pre-algebra, Algebra 1 and 2, and geometry.
Yes. Ask for word problems in the description, and add a context such as sports, animals, or food if you like.
Pick the grade, which sets the kind of numbers and operations, then choose easy, medium, or hard.
Yes. Every problem has an answer, printed on a separate page. Work a few problems yourself before handing the set out, since AI-generated math can contain mistakes.
No. It writes problems. To grade completed work, upload it to GradeWithAI, which reads handwritten math and gives partial credit under your rubric or answer key.
