Grade 4
homeschool curriculum.

Fourth grade is when math switches from concrete to abstract — fractions and decimals don't behave like the whole numbers a kid is used to. Cullinan's adaptive tutor catches the misconceptions early instead of letting them fossilize.

What Grade 4 works on

The core skills your kid will build this year.

  • Long multiplication + multi-digit division
  • Fractions: equivalence, addition, subtraction; decimals to hundredths
  • Paragraph essays citing textual evidence
  • US history: explorers, colonies, Revolution
  • Earth + space: rocks, weather, solar system
The Cullinan approach

By 4th grade, kids can self-direct most of a 60-90 minute session. The daily plan tells them what to do; the tutor delivers it; the parent dashboard shows you exactly what happened, sortable by kid, subject, and time spent. You're not the curriculum — you're the supervisor.
