Know exactly who understands tomorrow’s lesson before you teach it.

Assign any AP free-response question. Every answer comes back scored against the rubric, with the rubric point your class missed most.

Grade your first FRQ free Apply as a founding teacher

35 students and a 4-part FRQ is 140 rubric decisions. Fivefold makes them in seconds, and you check any of them.

Each response is scored one rubric row at a time, the way the exam scores it: DBQ and LEQ rows, lab investigations, calculus justifications, Java methods.
See which rows the class earned and which it missed, with the mistakes students shared.
One pick for tomorrow: the rubric point most of the class fell short on, and the students to pull into a small group.

Reteach tomorrow: Sourcing

19 of 27 students fell short. Named who wrote the document but never said why that author’s purpose or audience matters to the argument.

Plan: Model sourcing on Documents 2 and 6, then a 10-minute sourcing drill.

Assign a free-response question
Any unit, any of the 42 AP courses. Results fill in as students submit.

Don’t take its word for it. Check it.

Open any response next to its score and mark each rubric row the way you would. Fivefold keeps a running count of how often it agreed with you.

Every point comes with the student’s own words that earned it, and what would earn the rest.
Each check takes one click per rubric row, right beside the response.
The scorer reads the answer, never the student’s name or email.

Strong experimental design answers. The justification describes the result instead of explaining it.

What worked

Named the variable and the reason it has to stay fixed.
The prediction is clear and matches the setup.

Next steps

When a question says justify, name the mechanism: what happens to the protein and why that changes the rate.

Part (a): Independent variable
1/1 points, full credit
Temperature is the variable the student changes on purpose.
From your response
- The temperature of the water bath
Rubric criteria
Identifies temperature as the independent variable.
Part (b): Controlled variable
1/1 points, full credit
Names a controlled variable and explains how it would change the result on its own.
From your response
- more of it would make more oxygen even at the same temperature
Rubric criteria
Names a variable to hold constant (hydrogen peroxide concentration or volume, amount of catalase, pH, time) AND explains that changing it would also change the oxygen produced, so the effect of temperature could not be isolated.
Part (c): Prediction
1/1 points, full credit
Correct direction, compared with the right control.
From your response
- Less oxygen would be produced
Rubric criteria
Predicts that less oxygen (or none) is produced than with unheated catalase.
Part (d): Justification
0/1 points
This restates the prediction. It does not say what heat does to the enzyme, or why the effect lasts after cooling.
From your response
- the enzyme works slower when it gets hot
To earn the missing point
Say that 80°C denatures catalase: heat breaks the bonds holding its shape, the active site no longer fits hydrogen peroxide, and cooling does not restore it.
Rubric criteria
Explains that heating denatures catalase: it disrupts the bonds that maintain the protein’s shape, the active site no longer binds hydrogen peroxide, and the change is not reversed by cooling. "The enzyme slows down when hot" does not earn the point.

Your response

Highlights are evidence the grader cited; the number is the rubric row.

(a)

The temperature of the water bath¹.

(b)

The amount of hydrogen peroxide, because more of it would make more oxygen even at the same temperature².

(c)

Less oxygen would be produced³ than with the unheated catalase.

(d)

Because the enzyme works slower when it gets hot⁴.

Proof you can hand your department

After a unit, one report: who practiced, how much, how accuracy moved, what the class learned, and the grading hours you got back. It ends in a paragraph you can paste into an email.
