## Reflection: Discourse and Questioning Logarithms - Section 1: Warm-up

Using a "row game" instead of a worksheet can be helpful for skill-building.  This method works well when it is possible to write two very different questions that have the same answer.

In a "row game" two students work on one worksheet that has two columns.  The answer to #1 in column A is the same as the answer to #1 in column B, so students can check answers after each question.  Asking students to practice this way instead of both doing the same worksheet has multiple benefits:

1. It helps students see that many expressions can be equivalent even though they initially look very different [MP7].
2. It helps students develop viable arguments because they try to convince each other that theirs is the correct answer [MP3]
3. Students find the "game" aspect of it engaging, which helps them persevere through difficult tasks [MP1]

# Logarithms

Unit 2: Exponential Functions
Lesson 3 of 11

## Big Idea: Logarithms are exponents! To evaluate a logarithmic expression, we ask "what exponent do we put on this number to get that number?"
