Geometry

Far Side Expansion

repost from Make Math Not Suck

I have been doing this activity LONG before computers were a staple in the classroom. (We won’t talk about how many years that’s been!) I love this project now as much as I did when I started.

I used to have a Far Side by Gary Larson desk calendar and each year I would keep the images and use it for this project. I don’t buy the desk calendar anymore, but you can find Larson’s comic’s online.

I take the comics and cut them equally into 3-4 congruent parts (depending on my groups). Students must work in groups of 3-4 to decide on a grid size for their original and a scaled paper size and grid size. Once they’ve worked together to draw this in, they start sketching their drawing box-by-box. We spend about 4 -50 minute class periods on this project.

The students have a lot of fun with this and are proud of their product when finished. It also reinforces teamwork. When one person doesn’t complete their part, a picture is hung up for viewing incomplete. So sad.

Here is the planning guide I use for this project. If you use it, post about about it on Twitter, and tag me @MandiTolenEDU.

Apps with Google Slides

I stumbled across this post by @micahshippee on Kasey Bell’s website ShakeUpLearning.com. Micah is part of my Google Innovator Cohort and he is amazing.

Micah created an activity where students use Google Slides to create an “app” that you can load on your phone or tablet. I decided to use this wonderful idea to review area formulas. My students created an app where you could click a button and find the formula and an example for each shape. I love when you create a project that students are excited about! This project fits that description.

Bonuses: Students were VERY ENGAGED. They were still working when the bell rang and didn’t really want to stop. They were helping each other, critiquing without being prompted, and giving great advice. I was MORE THAN excited when students came into class the day the assignment was due with the app already loaded on their phone. They were soooo proud!  I think, as an extension of this activity, we will share our apps with lower grade levels, who are learning about area for the first time, and have them give us feedback through Flipgrid.

Here is the activity I gave the students. My instructions are taken directly from Micah’s post because they are so thorough. He is cited in the activity.

Create an App for AREA (1)

I’ve also included some of the apps created by my students. OMGee, they make my heart happy. You should be able to click on the phone below and it will open a Google Drawing file where the links are active. If you use this activity, please share on Twitter and tag me @MandiTolenEDU and @micahshippee.

Imagine what else you could do with this activity!!!

Student Created Trig Word Problem

repost from Make Math Not Suck

For the last 9 years, I’ve had students do a Trig project where they use handmade clinometers to measure the height of an object taller than they are. I love this project because it shows the application of Trig and guides students through a thought process to solve this type of problem.

This year I wanted to shake things up a bit. I wanted them to do the same project, but this time I wanted them to write an angle of elevation word problem. Students struggle with the word problems, and writing them helps them understand the process and required information.

As always, I was blown away by the creativity of some of my students. Their word problems were hilarious! They were problems I would WANT to solve. I took a few and used them on our assessment.

Since we had a recent ice storm, pictures had to be taken inside. It was Homecoming week, so we had some interesting backdrops. Students used the HOCO decorations and wrote their stories around them. Aren’t kids great?

Angle of depression is still giving us issues so maybe next year I’ll have them measure something below them. Maybe from the bleachers or the top of the steps. Hmm… food for thought!

Stop Motion Videos

Stop Motion videos in Google Slides is such an easy project for teachers and students. I first learned about Stop Motion from @ericcurts on his blog Control Alt Achieve. @jmattmiller also has some fun stop motion information on his blog too.

I created a super short little stop motion that I turned into an animated gif using Tall Tweets then embedded into a Google slide presentation, even cropping it because it acts as an image.

Stop motion videos are super easy to make in Google Slides. For the one above, I created background then I drug in my Bitmoji and placed it at the top.

Next you duplicate the slide and using the arrow keys or sliding with your mouse, move your image a little bit.

 

 

 

Screen Shot 2018-09-29 at 9.16.20 PM.png Continue the process until you have moved your object to the end.  This short little movie had 11 slides total.

Now the fun begins. Using the website Tall Tweets, load your Google Slide, this sometimes takes a bit depending on the size. Next, select the duration. Play with this a little until the movie looks like you want. You can check by clicking the create gif button. When you are happy with your movie, you can save it or tweet it.

Below are some stop motion videos I created for a Triangle Congruence lesson. So yes, you can use stop motion for academic purposes too. Image how much fun it would be for students to create their own!

If you make stop motion videos, please share and tag me on Twitter @TTmomTT. I would LOVE to see them!

Choose Your Own Adventure *Updated*

A lesson is only as good as the updates you make. This activity, which I first blogged about here and here, came from Ditch That Textbook by Matt Miller. I love this idea and now use it as an alternative assessment activity. Please go back and read how this started for me.

One reason I love this activity so much is because it gives students choice and freedom of topic, they become the teacher so they learn the content more deeply, they peer edit which is a very crucial skill, and this year I added a Flipgrid component in collaboration with another school.

I have updated my planning documents a little. They are posted on the posts, but this will be the most up-to-date document I have. I have also created a Google Slide presentation so very little teacher direction is needed. Another update I made this year was to increase the level of peer editing. Students do not intuitively know how to do this, so I updated the document so they have a little more guidance. Lastly, and probably the most exciting part for me, was creating these CYOA stories for a sister class in another district. We sent them our completed stories and then each student left feedback via Flipgrid. We’ve sent our stories to this district before but having video Feedback through Flipgrid was amazing and meant a lot more for my students.

I’ve included some fun examples from this year. I encouraged my Geometry students to create circular images as part of the story.  You can check the links above for examples from previous years including some Algebra 1 examples.

Including the Flipgrid responses from our sister school was an amazing addition. My students loved seeing the faces and hearing their reviewers. It also made the audience “authentic” to them. We did get permission from their parents for my students to view them but we did not include releasing it publically so I can’t share the link to the grid. I’ve included a screenshot of the grid below.

Here is an example of a peer review. In my experience, you need to model this for your students. I have, in the past, peer-edited my own story with the class so they see what to look for.

Please give credit to Matt Miller and me if you use this idea. It has been a fabulous learning experience in my classroom and I look forward to the next update!

Geometric Town Project

This is a culminating project that we do in Geometry. It was originally created by a colleague of mine who has since retired. It has gone through many revisions over the past 6 year. I love that it reviews parallel line angle relationships, equations of lines, properties of quadrilaterals, perimeter & area and equations of circles. Not to mention it allows for some student choice and creativity. I’ve posted the most recent update and some examples of student work. Students create the map of a town using the specified guidelines from the town planner.

This is a wonderful end of the year project to tie in with previous knowledge. I hope you can use this in your classroom.

Measuring height with Trig

I started to share this project with someone the other day and realized I had never written a blog post for it. We have used this project for quite some time and I love the digital aspect having students label their image and explain their process. We have the students make the clinometers but we give them little guidance as far as the project goes. We want them to problem solve and figure it out. We simply tell them to go measure something bigger than they are. I also limit their travel to school grounds (I did have a student go to the nearby gas station once. You have to be specific!!) I had a group of students last year that forgot their tape measure so they measured in shoe length (yes, I had a one-shoed student outside) and then converted that to inches when they came inside. I love the thought process behind their solution!

Not only does this give purpose to the study of trig, it also gets students outside and working together. It also helps students understand angle of elevation a little better with concrete examples.

I love the first one. She wrote a word problem for her image. Hmm… might have to steal that idea!!

I’ve included my clinometer document (I did steal the image from someone, sorry whoever you are!) and my scoring guide.

Popcorn Containers and Volume

Anytime you can have food in class it’s a good day (unless you are the custodian sweeping up popcorn. I’m sorry!) I came up with this project probably four years ago. We did the whole pour the water from a cone into a cylinder thing, and it was ok, but I wanted something better. While eating popcorn at the movies, my daughter and I started talking about the cost of the popcorn and the sizes available. Putting those two ideas together, this project was born.

The first year I had students create a cylinder and then figure out how to make a cone with the same base area and height. This was a struggle and I ended up showing them. It does involve a lot of thinking and many would not have gotten there on their own. The following year, I created a hand-drawn example of how to calculate the dimensions of the cone. I now have the information in Google Slides for students to use.

There are great discussions about the slant height becoming the radius of the cone. I do have to show students a visual of this and they are always amazed. Once they see the visual and we discuss how the circumference of the cone piece has to meet up with the base circle, they begin to see how it all fits together.

I’ve included the activity for the first day. I’ve popped trashbags full of popcorn and I’ve popped microwave popcorn. If you can get your concession stand to open up their popcorn machine then you have it made.

Popcorn Container Activity

As a follow-up activity, I decided to have students calculate the cost and the amount for which they could sell their popcorn. This allows them to make some decisions about which container would be best. Many of them tell me that it doesn’t matter which one is the best deal because the cone of popcorn would be inconvenient. 🙂

Bitmojis in the Classroom

Hi.png

If you’re not familiar with Bitmojis, YOU ARE MISSING OUT! It’s you in an avatar with a ton of different sayings and situations. It’s an app you can download (iOs & Android) and a very user friendly Chrome extension.

It is fun, but it also has a TON of applications in the classroom. Since it integrates with Chrome so well, you can drag your bitmoji into most Google Apps as feed back for students.

2016-11-11_07-41-51

Sometimes my students leave me “suggested” feedback through Bitmojis as well. a

I recently used Bitmojis to enhance my Superhero Transformations activity for Geometry. It was a HUGE hit!

This idea came from a discussion with the AMAZING Sylvia Duckworth. I’ve included her slide deck full of ideas as well. My example is on there but so are a ton of other amazing examples of how to use Bitmoji comics.

Here is the example I gave my students. We also had a quick exploratory lesson about how to transform the Bitmojis through the arrange menu (or 2 finger click or key command) and a quick lesson on how to crop and mask images.

I was even more impressed after my students submitted their projects.

Example 1     Example 2    Example 3   Template to create your own (make a copy to edit it)

I created some examples for my non-math friends when I presented this to my school. How about a comic in a foreign language, or a political cartoon?

Now if you are a fan of Snapchat, you probably already know that Bitmojis are sticker options inside of it. You can also send “together” bitmojis in a message.

me & my daughter

Tara Martin shared her idea about using Snapchat and bitmojis with book selections and a new hashtag was born – #booksnaps. You take a pic of a book selection you like, annotate & add your bitmoji. Read about it on Tara’s blog here.

booksnap-example

And if you don’t want to open the world of Snapchat in your classroom, this can be done through Google Drawing or Google Slides.

A quick disclaimer on Bitmoji, there are a few that are not school appropriate. This isn’t any different from anything else you find online. Talk to your students about using Bitmoji responsibly and open up a whole new world for them.

CYOA Geometry Style

Choose Your Own Adventure was such a success in Algebra that we wanted to try it in Geometry. This served as our unit 7 assessment. We followed the same process that we did here but I did update the process so students could plan electronically using this planning form. I also had students create this in New Forms so the process is slightly different than my original post.

The biggest difference between old Forms and new Forms is inserting a page compared to new section.

Untitled drawing (4)

We also used Google Drawing so students could create their geometry problems using tangents, secants, arcs & chords. Many students had never used Google Drawing and they were very excited how nice their images looked.

Two Tangents

Students had to get 3 peer reviews, which meant a student worked through their adventure, correct and incorrect answers, then gave feedback on improvements. They used this document to guide them through the peer reviews.  The result SHOULD have been a product that met all of the requirements. Some students don’t peer edit as well as other but they learned quickly that being NICE doesn’t help you improve.

Here are a few of my favorite projects. I told them I wouldn’t publish them unless they were correct. 🙂
