The K12 Academics Lesson Plans library is a free resource of 1,502 interactive lessons spanning 9 subject areas, from Pre-Kindergarten through Grade 12. It is built for teachers, homeschoolers, tutors, and curious students who want a complete lesson they can open and teach today.
What makes every lesson different
Most lesson-plan sites hand you a document. Every lesson here is a self-contained, animated teaching kit with four tools built in, so there is nothing to prep or piece together:
Lesson Plan
Objectives, a warm-up-to-reflect flow, an interactive whiteboard activity, and differentiation for ELL, IEP, and extension.
Flashcards
Eight key vocabulary cards to introduce and review the lesson's core terms.
Practice Quiz
A six-question check for understanding that scores instantly.
Worksheet
A printable word-bank worksheet with an exit ticket and a toggle-able answer key.
Who publishes this
The library is published by K12 Academics, an education resource website online since 2004. K12 Academics is one of the largest education resources online, with 200+ national and international directories across six categories: K-12 schools, colleges and universities, education vendors, summer programs, international programs, and performers. Its mission is simple: help people find their community and the right school, program, and resources within it.
Standards alignment
Each lesson references widely used learning standards to make planning easier. Depending on the subject, that includes:
- CCSS - Common Core (Math & ELA)
- NGSS - Next Gen Science
- C3 - Social Studies
- CASEL-5 - Social-Emotional Learning
- NCAS - National Core Arts
- SHAPE - PE & Health
- CSTA / ISTE - Computer Science
- ACTFL - World Languages
An important note on alignment. These standards references are provided for planning convenience only. K12 Academics is an independent education resource and is not affiliated with, sponsored by, or endorsed by any of the standards organizations named above or their governing bodies. Standard names and frameworks are the property of their respective owners.
Lessons are provided free, "as is," for educational use. We work to keep content accurate and useful, but educators should review each lesson for fit with their own curriculum, students, and local requirements before teaching.
How to use the library
Browse by subject or by grade, or search the whole library by topic. Open any lesson to project it on a board, print the worksheet, run the quiz, or share the link. Everything is free, and the collection keeps growing.
