## 8.13 Do Now.docx - Section 1: Do Now

# Show what you know

Lesson 13 of 22

## Objective: SWBAT: • Show what you know about range, median, mode, and mean. • Show what you know about statistical questions, histograms, and dot plots.

## Big Idea: What do students understand? What gaps do they have in their understanding? Students review and take the quiz.

#### Do Now

*5 min*

See my **Do Now** in my Strategy folder that explains my beginning of class routines.

Often, I create do nows that have problems that connect to the task that students will be working on that day. Today I want students to think about the difference between a ratio and a rate. I want students to understand that a ratio is a way to show a relationship between two amounts. A rate is special type of ratio that shows a relationship between two measurements.

#### Optional Quiz Review

*15 min*

**Note:**

- Students need to have access to laptops for this review.

Before students take their quiz, they can work on this game to review measures of central tendency. Students walk through and pick up artifacts. Students then have to answer questions about the median, mean, and mode of the artifacts.

As students work, I walk around and monitor student progress. With a few minutes left I have students pack up and put away laptops.

#### Quiz

*30 min*

For this quiz I used a couple of different resources. My school has a membership for www.testwiz.net. This website has a very extensive item bank of Common Core questions. I search by standard and make modifications as necessary. Also, my school has subscription for the assessment bank for the College Preparatory Mathematics curriculum. The bank has a wide variety of rigorous multiple choice and open-response questions. See www.cpm.org for more details.

I give students the **Quiz.** Students engage with **MP1: Make sense of problems and persevere in solving them**. If students do not finish in the allotted time, they set up a time (preferably that day) to come in and complete it. I use this data to inform my instruction. If students struggle with a concept, I will spiral it into do nows and homework assignments. I may also add a few problems on that topic to the next quiz.
