Frequently Asked Questions

Differentiated instruction is a teaching approach where educators adjust content, process, and products to meet individual student needs. Instead of one-size-fits-all lessons, teachers provide multiple pathways so every learner can access the curriculum at their level. Adaptive apps automate much of this by adjusting difficulty in real time.

Our Verdict

IXL is the most comprehensive adaptive platform for differentiated instruction across all subjects and grade levels. Its real-time difficulty adjustment means every student in your classroom gets a personalized experience without extra teacher prep.

For math-specific differentiation, DreamBox and Prodigy both excel — DreamBox with its visual scaffolding approach, and Prodigy with its game-based engagement that keeps reluctant learners motivated.

For reading intervention and RTI, Lexia Core5 is the gold standard, used in 1 in 4 US schools with research-backed adaptive pathways.
