Crow's Challenge (Grade 8 Math: Functions and Irrationality)

Description

A challenging mathematical problem that invites students to consider how the presence of radicals may or may not affect whether a function is linear.

Includes a skill summary, a detailed solution walkthrough, and a sample exemplary student response.

The problem itself is presented in grayscale for ease of printing; all other slides are in full (RGB) color for display as a slideshow.

Questions & Answers

CCSS8.NS.A.1

Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.

CCSS8.NS.A.2

Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π²). For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.

CCSS8.F.A.1

Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.
