8th Grade Math: Units 3 and 4

Here is a picture dump! I'll try to compile a list of original resources that I borrowed from and then share what I can. But for now, a pictographic story of my interactive notebook for units 3 and 4.

I have added a few, quick notes about particular times under the photos.

The "Remember on my Retest" pages is a blank organizer that lists each objective on our test. Students fill out reminders to themselves about what to study as they make corrections to their original test. For more on retesting my classroom, see my post here.

The large, block letters on the right side of the page were a coloring activity. Students colored it just like a coloring book - in 8th grade. Yep... most of them loved it!!

The picture below is the "from points/from a graph" foldable open.

The cards on the right were a matching activity. Students worked to match a graph, table of values, equation, slope value, and y-intercept value. They stapled their matches all together and taped them in.

 --card sorting activity--

Desmos investigation. More info can be found here.

Students wrote their names in block letters and identified the types of slope for each section of their names.

The inside of the slope foldable is shown below.

The above was a small matching activity. Some of the graphs and scenarios were lose and students had to match them to the ones already given. It really made them look at and examine axes.

That's all for now!! :)

UPDATE!
Here are all the files. There are TONS since we did a lot of pages and a lot in class. I've included all the editable word/publisher files as well as the pdf version to preserve formatting and fonts. Use whatever you want! 

Desmos Investigation

Remember this tweet? From November 6th? Gulp...two weeks...so sorry!

8th graders investigated slope and y-intercept using @Desmos. Great discussions! Blog post coming soon. #edtech #mathchat #celebratethegood

Better late than never?? :) Right??

Background: We have been doing a lot tasks and investigations that form linear functions, the kiddos just don't know that's what they're called yet. They think we're just saving money, changing temperature, renting ATV's etc. They were catching on about constant rate of change and initial values, though, and we started writing equations and drawing graphs that represented our scenarios...

Then, I did this one day.

Students set up their interactive notes pages like this...

Then they paired up with a partner and got a laptop.

I gave each group the following directions:

Glorious and wonderful mathematical investigation followed...

We then debriefed as a class. 

The ideas of slope, y-intercept, slope-intercept form, horizontal lines, and vertical lines all came together wonderfully!! I even had at least one student in each class that remarked something similar to "I can't make a vertical line because it isn't a function, right?" Oh yes, dear child, you are right. 

Thank you for making this math teachers day!!!! :) 

What is your favorite use of Desmos so far???? Please share!

Desmos Piecewise Project

This has been my favorite project for two years now! I have reserved the computer lab for an entire week each time and let the students show their skills!

Here 

is the project overview I give students about a month before we go to the lab. They complete their sketch on graph paper and record their functions with domain constraints. I tell them that once we get to the lab they need all the time they can get to input functions into Desmos and mess with colors. Inevitably they also have to tweak some functions to make it work. If most of their ideas are already on paper it makes the week go much more smoothly.

They work so hard writing functions of all kinds, not just limited to our Algebra 1 skill base. I have students independently researching conics, logarithmic functions, and working so hard to make their details perfect. I have printed these in color both years and put them down the hallway.
Best comment of last spring: "I didn't know algebra could be that cool!!!"

Here are some awesome student works:

Gah...8th graders!!! Love them!!!!
