What are the best websites for teachers to use in the classroom?

Updated October 2026 · How we answer

Short answerThere's no single 'best' site—it depends on your grade level, subject, and devices. Start with a few reliable, free tools like Kahoot!, Khan Academy, and Google Classroom, then add others as needed.

Top Picks by Category

For interactive quizzes and games, Kahoot! and Quizizz are popular and offer free versions. For video lessons, Khan Academy and YouTube (with careful curation) provide vast libraries. For classroom management and assignments, Google Classroom and ClassDojo are widely used.

For elementary reading and math, sites like Starfall, ABCya, and Prodigy are engaging and curriculum-aligned. For secondary grades, Desmos (math), PhET (science), and CommonLit (ELA) are strong free resources.

  • Kahoot! – game-based quizzes
  • Khan Academy – video lessons and practice
  • Google Classroom – assignment hub
  • ClassDojo – behavior and parent communication
  • Starfall – early literacy
  • PhET – interactive science simulations

How to Choose

Consider your students' ages, your device availability, and whether the site works offline or requires logins. Check if it offers a free tier that meets your needs without forcing upgrades.

Look for sites that are easy to navigate, have clear learning objectives, and don't overwhelm students with ads or distractions. Read reviews from other teachers on sites like Common Sense Education.

Common mistakes

  • Assuming a site is best just because it's popular; what works for one class may not work for another.
  • Overloading with too many tools at once, which can confuse students and waste class time.
  • Ignoring privacy policies and data collection practices, especially for sites that require student accounts.
