# Explicit Instruction

Explicit instruction is a critical feature in teaching students who struggle with math. By walking through exactly what you want a student to know and allowing them time to practice, using explicit instruction in your classroom can help you reach students who may otherwise struggle. In this video, Sarah Powell from UT demonstrates how to use explicit instruction in the classroom.

# Mathematical Language

Most people don’t realize it, but the words that we use to teach a concept have a huge impact upon students learning. Math is an especially tricky area where teachers must be precise and use the right word or they could confuse their students. Sarah Powell examines both the challenges of using proper mathematical language as well as strategies and examples to help teachers use precise and specific language to help students learn math.
