# Rigour and Vocabulary

## Why is it important to show students the benefits of paying rigorous attention to details and using vocabulary correctly?

Here is a series of three consecutive problems that Anna addressed with a small group of students in her Year 9 classroom. Notice how Anna explores her students’ ideas to help them better understand the vocabulary they struggling to understand.  Anna addresses their questions about gathering like terms, understanding when the negative sign means “negative” or “subtraction”, and explores what exponent notation means in a particular problem.

• Anna: Small Group Teaching Part 1 Notation, Gathering Like Terms
• Anna: Small Group Teaching Part 2 Notation, Negative or Subtraction?
• Anna: Small Group Teaching Part 3 Notation, Confusion about Exponents

## What are some effective ways to show students how to use rigour and correct vocabulary?
