Block periods, typically around 90 minutes, offer both opportunities and challenges for teaching and learning. On one hand, they allow for deeper exploration of material, extended practice, and more meaningful engagement with complex ideas. On the other hand, they require intentional planning to ensure that instructional time is fully and effectively utilized.

The key to an effective block period is not relying on a single instructional method, but thoughtfully structuring time into purposeful segments. Strong lessons intentionally balance direct instruction, student practice, application, and reflection. Without this variation, even well-planned lessons can lose focus or momentum.

In many ways, teaching in a block period is about “portioning” learning experiences so that students remain engaged while still being appropriately challenged.

A helpful way to think about lesson structure

One suggested model for planning a 90-minute block includes:

• An engaging introduction or anticipatory set

• Direct instruction

• Student application and practice

• Formative assessment or check for understanding

• A closing moment that brings ideas together

While this structure will not fit every lesson or subject area, it can serve as a useful framework for thinking intentionally about pacing and variety within longer instructional time.

Essential takeaway

Effective block-period teaching is less about filling time and more about designing meaningful shifts in activity and engagement throughout the lesson. When students move between listening, doing, applying, and reflecting, learning becomes more active, focused, and enduring.
