Which of the following is an integer?

-3

B

1 |

4 |

C

-12.5

D

0.454545...

## Standard: 8.NS.A.1

## Domain: The Number System

## Theme: Know that there are numbers that are not rational, and approximate them by rational numbers

## Description: 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.

Between which two integers does √2 lie on the number line?

A

0 and 1

B

1 and 2

C

2 and 3

D

3 and 4

## Standard: 8.NS.A.2

## Domain: The Number System

## Theme: Know that there are numbers that are not rational, and approximate them by rational numbers

## Description: 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., ?^2). For example, by truncating the decimal expansion of ?2 (square root 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.

Between which pair of consecutive integers on the number line does √3 lie?

A

1 and 2

B

2 and 3

C

3 and 4

D

4 and 5
