Graider is for math teachers who still collect paper. A quiz on equations, a page of fraction work, or a unit test comes back as handwriting: a final value on the last line, and the steps above it. Your answer key already says which of those lines count. Graider for math teachers applies that key to the photographed stack.
Graider is the AI red pen for paper grading, a product of DM Liquidity LLC. You upload the test and your answer key or rubric, photograph the stack of student papers, and Graider marks each question against that document. You review and override, toggle feedback, keep the pen, and hand the work back as a PDF or an email. Paper tests follow that path in AI test grading.
Your key. Their worked solutions. You review every mark. You keep the pen.
This page is the math-teacher workflow: final answers and expected steps, partial credit as a finished score, review and override, and the Low confidence badge on hard-to-read handwriting. Graphs, diagrams, and constructions stay with you. Method marks and a later part that uses the student's earlier number are in AI math grading for paper tests.
A math answer key a colleague can use has two parts for each question. The final answer is the value or the form you accept. The expected steps are the lines a second reader can point to: the setup, the operation, and the simplified form.
Number the question the same way on the test and on the key. When part (b) is its own question, give it its own final answer, steps, and total. Graider returns one score and one comment per question, taken from those steps and that final answer.
On "Solve 3(x + 2) = 18," worth 4 points, name the final answer x = 4 and the expected steps: distribute or divide first, isolate x, and state the value. When you accept two methods, such as substitution and elimination, write both, each with its steps, its final answer, and the points that method earns. A method you have not written is one you score at review. Add that line to the key for the next test.
Partial credit for a worked solution is a finished score on the key or the rubric, written before the stack is marked. Each line names what is on the page and the points that case earns. The line the paper meets is the one score for that question. The one comment can name the line.
On the 4-point equation, the key can read:
A paper matches one of those lines, and that line's points are the score. Use the fullest line the paper meets. A rubric level names what is present, what is missing, and the one score that level earns. Writing those finished scores is covered in partial credit grading with AI.
AI grading for math teachers follows the documents you uploaded. To grade math tests with AI, photograph every page, including the back, any extra sheet, and algebra in the margin. Keep each student's pages together.
Keep a score when the work matches a line. Override it when you disagree, and edit the one comment so it names the line or the reason you set the points. You can override any question. Each question still carries one score and one comment. When you accept a method the key left out, use the same points on the other papers that show it, and add the line for the next test.
Feedback is a toggle you set before handback. Turn it on when the comment should appear on the PDF or the email. Turn it off when the class will go over the item and only the score should appear.
The Low confidence badge is the only flag. It sits on an answer Graider found hard to read.
Read the student's answer as text. Compare that text with the paper and your key, and confirm the question number. Read a crossed-out step and the step written above it against the page. If the text left one out, override the score to match the full work you see, using a line on your key or points you set when no line fits. You can override a score with a badge or without one.
Graider does not read or score diagrams, graphs, or drawings. A graphing question needs you to mark the figure: the plotted points, the line or the curve, the scale, and the labels. A geometry construction needs you to mark the drawing: the compass marks, the triangle, and the right-angle mark. Put those points into the one score and the one comment for that question.
A written equation on the key can stay inside that same score. The sketch beside it is still yours to mark. When a Low confidence badge sits on the words next to a graph, check the words, then mark the graph yourself.
Before you finish review, check:
Hand each paper back as a PDF or an email after that check. The score is the one you kept. When feedback is on, the comment you kept sits with that question. Graider emails the student account a "Your grade is ready" notice and does not send the paper to families.
Student papers and account data aren't used to train models or for advertising.

Give the question a total. Write the final answer you accept and the steps a colleague could find on the page. Number the question the same way on the test and on the key.
Write each partial as a finished score on the key or rubric. A line such as "correct steps, arithmetic slip on the last line: 3 of 4" is the one score for a paper that matches it. You can override that score at review when you disagree.
