Happy Wednesday! We are getting ready to start working with mean, median, mode, and range, so I have been working on a new "Fold It Up" for my students (linked below).

### Writing Goal

I haven't spent much time on my blog lately:( I've been pretty good at getting the Workin' On It Wednesday link up posted each week, but not much beyond that. So, one goal is to write at least three times this week. I'm going to branch out a little from just classroom topics, and share a bit about other things. Today's topic - my puppies!

This is Lily "posing" for the camera. My daughter likes to say that she's modeling. She has the greatest personality - so friendly, attentive, and curious. She watches TV with us and shows such an interest in what's happening. Below, she's chewing on a "skull" toy that they've had for years....there's just something about it that she and Oreo love. There can be three other toys around, but they'll "fight" over this one.

Lily and Oreo love to cuddle....often times, she'll crawl right on top of him to lie down- or on me, or on whoever is available - she's so funny!

Lily is 6 and Oreo is 10, and they are the most affectionate dogs. They literally follow me everywhere I go, except upstairs, because they aren't allowed. They know where I am though, and they wait for me at the bottom of the stairs...

Oreo was our first dog as a family, and because he was such a wonderful Boston that we had to have more!

They are fantastic pals!

### Workin On It Wednesday 4/16

This week, I'm working on finishing up one more day before a 3-day weekend that includes my birthday:)

We've worked on finding percents of numbers, as well as converting fractions, decimals, and percents...for which we've used our FDP Fold it Up and our FDP Number Line (both linked below). Test tomorrow!

### Rumors!

Rumors is another great lesson from Mathline! This lesson allows students to explore exponential growth, in the context of spreading a rumor. In addition to the focus on math concepts, this lesson can also help students to understand how quickly rumors can actually spread....an important idea for middle schoolers to consider.

To begin the lesson, students are presented with the following scenario:

Students can act out this scenario by having students form a human triangle, with Student A first, then the two students she told (students B and C), then four students representing the two that Student B told and the two that Student C told, etc (as far as possible, depending on how many students in the class). This will help students visualize the problem and understand how this rumor is being spread. The triangle also help students to understand the growth pattern.

The human triangle will only go so far, so students will then need to use their calculators or paper and pencil to find how many days it will take for the rumor to reach 8,000 people. I would recommend providing the students with a blank chart to give some structure to the students' work after they try the human triangle.

The chart below includes the first several days (the numbers for the entire chart can be found in the lesson).

In addition to understanding exponential growth, students can be asked to determine the algebraic expression to describe the number of new people to hear the rumor each day (2

To read the full lesson and the possible extensions, check out the lesson here.

To begin the lesson, students are presented with the following scenario:

*"Two students who were both born on December 21st, the date of the winter solstice, decide that it would be great not to have to attend school on that day. Therefore, they start a rumor that schools will be closed to celebrate the winter solstice. So, on December 1st, one of the students told two of her friends that school would be closed. On the next day, each of these students tells 2 students and on consecutive days, each of the new students tells 2 more students and so on. If there are 8,000 students in the school district, the question arises as to whether the rumor was started early enough for everyone to have heard it?"*Students can act out this scenario by having students form a human triangle, with Student A first, then the two students she told (students B and C), then four students representing the two that Student B told and the two that Student C told, etc (as far as possible, depending on how many students in the class).
