Objectives, a hook, direct instruction with worked examples, guided and independent practice, differentiation, and an exit ticket — generated in one pass from a single topic description. Edit any section before you print.
Measurable learning objectives tied to standards
Time-blocked phases with teacher and student actions
Differentiation for struggling learners, advanced learners, and ELLs
Formative checks and a closing exit ticket
5th grade math · 45 minutes · CCSS 5.NF.A.1
Objective
SWBAT add fractions with unlike denominators using common denominators and fraction tiles.
Warm-up: estimate 1/2 + 1/3 using fraction bars. Predict whether the answer is more or less than 1.
Model 1/2 + 1/3 with fraction tiles, then the algorithm: find a common denominator, rename, add.
Guided practice on 3 problems with scaffolded difficulty. Partner check after each.
Independent set: 6 problems. Teacher confers with 2-3 students.
Exit ticket
3/4 + 1/6 — show your work with a fraction bar and the algorithm.
Any framework, any format
Name the instructional framework in your prompt and the plan restructures. Inquiry-based science gets 5E phases. Backward-design units get desired results first. Content-with-ELLs gets dual language and content objectives. You're not locked into one format.

About this tool
Biology lesson plans balance macro-scale phenomena (ecosystem dynamics, evolution) with micro-scale mechanisms (cellular respiration, DNA replication). This generator produces biology plans that use investigation-first structure — students observe a phenomenon or run an experiment before the teacher explains the mechanism — aligned to NGSS life science standards.
Biology is hard to teach because the interesting stuff is mostly invisible — cells, molecules, ecosystems over time. Good biology lessons use concrete analogs, models, and simulations to make the invisible visible. This generator produces plans that explicitly name the model or analog being used (paper models of DNA replication, bean-counting simulations of natural selection, simple yeast-based cellular respiration labs) rather than relying on pure abstraction.

Hands-on investigation before direct instruction
Claim, Evidence, Reasoning for student explanations
Connection between cellular and organismal scales
NGSS organizes life science around four DCIs: From Molecules to Organisms (structures and processes), Ecosystems (interactions, energy, dynamics), Heredity (inheritance and variation), and Biological Evolution (unity and diversity). This generator names which DCI each lesson targets and sequences instruction so related DCIs connect rather than staying siloed. Evolution and heredity, for example, only make sense when taught in connection, not in separate units.
Biology labs range from microscope work (cell structure) to ecosystem field studies (biodiversity sampling) to model-based investigations (natural selection simulations). This generator produces plans with specific lab protocols appropriate to the topic and the available materials. Specify 'no specialty equipment' in your prompt if you're a teacher without a full bio lab, and the plan uses household or low-cost materials instead.
How it works
Topic, grade level, subject, class length. Paste standards, unit objectives, or a single sentence — whatever you have.
Time-blocked phases with objectives, activities, differentiation, and assessment — matched to the framework and cognitive load you picked.
Review, tweak any section, toggle standards on or off, and export a clean PDF. The output is a draft you control, not a black box.
Hear from teachers who are saving time and providing better feedback.
“For Chadwick users, GradeWithAI has improved feedback efficiency and effectiveness, as it is grounded in existing platforms and is highly adaptable.”

“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.”

“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.”

“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.”

After the lesson
The lesson plan generator is free forever. When your students turn in what the lesson produced — an exit ticket, a worksheet, an essay — GradeWithAI scores handwritten and digital work in seconds.
