# Quiz 2 Showing Our Understanding of Decimals

Lesson 11 of 12

## Objective: SWBAT compare and plot decimals on a number line, explain equivalency of decimals, and convert decimals to fractions.

To get our minds wrapped around our quiz, I wanted to do an activity that would stir up their thought process on comparing decimals. I gave each student a number card that had decimals written on them. Their goal was to get themselves ordered from least to greatest correctly.

I started by having them flip their card over to look at the decimal number. I told them that I wanted them to form a number line with their cards at the back of the room from least to greatest going left to right, just like a number line. I set the timer and they got going! Collaboration

There was noise, rushing around, checking, comparing and discussions and disccovery!We all have 21! Students approached me when they were figuring out three of them had the same decimals. They couldn't believe they were right. Finally, our number line came together in a matter of 3 minutes. Getting it together!

I asked them why they were able to get it together so fast? One student replied that it's because they "get decimals now!"

#### Quiz Time!

*25 min*

I wrote this quiz to assess three things:

1) I want to assess their ability to compare and plot decimal numbers on the number line.

2) I want to see if they can explain the value of similar looking decimal numbers using tenths and hundredths. I try to include a writing and explanation component to every quiz and test because CCSS aligned state tests will expect this and I think it is just best practice to expect students to explain their reasoning.

3) I want them to show me that they can write decimal numbers as fractions.

I passed the quiz out and went over directions carefully, realizing that I had written the third standard incorrectly. I corrected myself and explained the expectation that they needed to show conversions of decimal to fractions in tenths and hundredths. ( Your resource is correct. The quiz is thirteen points total. Numbers one and two are worth 2 points each.)

Students wrote this quiz in about 20 minutes.
