Are you having trouble getting through a full lesson in one class period? Here are some tips to make you more efficient.

When getting ready to teach an EFFL lesson, many teachers worry: How will my students know how to do the activity if I haven't taught them yet? The key to students being able to complete the activity before instruction is in what questions you ask and how you ask them.

Write your own higher-level thinking questions with intentionality and efficiency.

Assess deeper understanding by varying your verbs. In this blog post, we'll look at three categories of verbs and how to write appropriate questions at each level.

We have explained how we teach using the Experience First, Formalize Later lesson design and also why this model is best for students. Here we will explain the ideas that we consider when designing these lessons.

In our previous post, we explained how we implement the Experience First, Formalize Later model in the classroom. In this post, we dig into the "why".

**Experience First, Formalize Later** means that students are working collaboratively to think, to discuss, and to construct their own understanding of new content before the teacher helps students to arrive at formal definitions and formulas.
