SLEEDU
SUPPLEMENTAL BY DESIGN

The all-in-one supplemental platform for teaching, learning, and teacher collaboration

One login. Every subject. Built by a classroom teacher to enhance the curriculum your district already adopted — and to connect teachers across schools and districts.

Get Sleedu Premium free for every course you teach this school year (limited seats available). Keep Sleedu Lite free forever. See both offers

Not a curriculum. No scope, sequence, or standards of its own.
Not a replacement. Works alongside your curriculum and its delivery tools.
Not AI on student data. No student data goes to any AI or third party.
Six capability areas, one platform

Everything a teacher needs, in one place

Practice, assessment, data, accommodations, interactive content, and collaboration — layered onto whatever curriculum your district has adopted.

Practice & Assessment Engine

  • 15+ question types: drag-and-drop, matching, cloze, ordering, numeric, graphing
  • Auto-scored with immediate feedback to the student
  • Unlimited practice, randomized variants, hints, multiple tries
  • Secure modes for state-test and AP-style practice

Teacher-Only Data & Analytics

  • Item-level results: what was missed, by whom, how often
  • Time on task, attempts, retake patterns, completion
  • Reteach and small-group decisions by the next morning
  • Exportable gradebook for parent communication

Personalization: IEP, 504 & EL

  • Per-student overrides: extended time, extra attempts, deadlines
  • Accommodations delivered quietly — no one singled out
  • Conditional release and branching lessons for mastery paths
  • Audio, video, and visual supports for English Learners

Interactive Content Authoring

  • Virtual labs, simulations, and drag-and-drop sequences
  • Interactive video, embedded media, rubrics
  • Standards mapping to your district’s frameworks
  • District-approved AI as a content partner — content in, never student data out

Teacher Collaboration & PLCs

  • Share courses, question banks, and simulations across teachers and sites
  • Shared item-level data turns PLC meetings into evidence conversations
  • Forums, glossaries, peer review; Administrator PLC Hub
  • A strong teacher’s course travels instead of staying in one room

Access, Security & Continuity

  • Google Login for every user; district MFA enforced automatically
  • Role-based, course-scoped access; teacher data never visible to students
  • AWS hosting with backups and cyber liability coverage
  • Any time, any device — absent students pick up where they left off
Beyond the classroom

Collaboration across schools and districts

Built once, refined by many. Every teacher who improves a course improves it for the next.

How it works

The daily loop that makes it work

Teachers build or share, students practice with instant feedback, data comes back, and the course gets better — for every teacher who uses it.

STEP 1 · TEACHER

Build or share

A practice set, lab, or assessment for the district’s adopted content — or reuse a colleague’s.

STEP 2 · STUDENTS

Practice with instant feedback

Any time, any device, unlimited tries. Accommodations applied per student.

STEP 3 · DATA

See who understood what

Item-level results by the next morning. Teacher-only. Exportable for families.

STEP 4 · TEACHER + PLC

Reteach, intervene, improve

Targeted small groups, MTSS tiers, and a better course for next time — shared back.

It’s the suit, not the hero.

Sleedu doesn’t replace the teacher or the curriculum. It lets the teacher reach every student — faster feedback, better data, more ways to practice — with the content the district already adopted. Subject-agnostic: science, math, ELA, world languages.
