Guess Who & Polygraph Lines

As we come to the end of the semester review days are here. To help grade 9s review properties of linear relations we played Guess Who. Last September I ran Guess Who with my grade 12 Advanced Functions class with great success. I made up a new sheet for grade 9 with a variety of linear relations (graphs, equations, and tables).

Guess Who game sheet

The students played a few rounds each! The questions coming out were pretty good! I overheard lots of “Does is show direct variation?”, “Does it have an initial value?”, “Is your graph decreasing?”
All great terminology I love hearing from my grade 9 applieds!!

After a few rounds of “low tech” Guess Who, we broke out teacher.desmos.com and “high tech” Guess Who —– Polygraph – Lines

Students use a class code to access the game. Round 1 is playing the orginal guess who with pictures of people against the computer. 
The system then links you up randomly with another student in your class. You take turns each choosing a graph and asking questions to guess your opponents graph!

Again, great questions and discussions here! I could see the deep thinking about what questions to ask to eliminate options. Desmos once again out does it! Linking up digital resources while keeping learning social!

These students have been great to teach this semester! I’ll miss them next year!!

Show what you know in Gameshow!

IMG_3350Last week, Kyle Pearce wrote a post on running GameShow by KnowledgeHook. I was drawn to this idea mostly because of review time coming up and wanted a nice way to practice EQAO multiple choice type questions. GameShow is great for that. I love that it works on any device. Students can use their phones, iPads, laptops, etc to submit their answers.

Today I created a custom GameShow to practice simplifying algebraic expressions with my students. KnowledgeHook has a bank of questions already to go…..I just did some picking and choosing of questions I wanted to tackle and added them to my newly created custom gameshow.

I stressed to my students to not worry about any time in the game. These multiple choice questions are not about speed. Let’s make them about accuracy. They played in teams of two with whiteboards beside their devices. I asked them to show full solutions on their whiteboards.

What was awesome while playing our GameShow today was that once students submit their answer they can upload a picture of their work!!!

On the teacher side, I could see how many solutions were uploaded for each answer option.Screen Shot 2015-06-03 at 12.22.07 PMAs a class it was great to choose correct answers and analyze them. All answers are anonymous until the teacher clicks the reveal.  It was equally rewarding to analyze the incorrect answers and talk about how we can make them better!!! Students seeing each others’ solutions is powerful!

Since I asked for all solutions to be uploaded the students started putting more effort into their answers! I find when we use other software like this, putting in an answer is like a game. “How fast can I get it in” Uploading slows it down and puts an emphasis on the solution! Like it!!! That’s the way a gameshow should be played!!!!

This program is super new so head on over to https://knowledgehook.com/gameshow/ . It’s free. And has content build right in. Even if you’re not from Ontario you can have access to the free bank of Ready Made gameshows or create your own. You actually don’t even need to teach math to make use of the gameshow!!!

Make it Parallel – An Activity with Parallel Lines

I find making the relationship among parallel lines and transversals real-world tough. So instead of real-world I went with Fake-World but making sure I incorporated space for curiosity and inquiry.

Here’s what we did…

I started class with a What do you wonder? What do you notice?


We recorded our wonderings. IMG_3327

Most students didn’t know what to say about it. Next I replayed the video and said, “I want you to yell NOW when the two white lines are parallel”

Kids were yelling out at about the same time……”Good, it’s awesome you guys can ball park when two lines are parallel”. Now Let’s create parallel lines.

I had already set up situations like this all over the hall, classroom, and outside. The prompt from me was “Create another line that cuts the transversal and is parallel to the first line. ” I also gave each group a set of pull back cars to “test out” their newly formed parallel lines…..We used them to show that the two cars won’t cross paths. Screen Shot 2015-05-26 at 11.58.44 AM

I let each group struggle with how to figure this out. I gave them all a metre stick, protractor, and markers/chalk.

We had discussions on how we know the two lines are parallel. I pushed each group to develop the angle relationships around the transversal.

Once each group had made the new path, they were to grab their iPad and access the Explain Everything file on Parallel Lines & Transversals. They were to use the interactive features such as the protractor, and pen tools to determine the answers to the questions.

Teach Math with Spiralled 3-Act Tasks – a full course

This semester was my first go at spiralling a course through problems instead of units. Traditionally we teachers follow the chapters and sections from the textbook. Well why not? It’s all laid out and organized nicely….most times in 1 day chunks….no planning needed, am I right???

How exciting is it though? How much do students really need to think? Are they really solving problems and learning mathematics.

After reading about spiralling from Alex Overwijk and bouncing ideas back and forth with Kyle Pearce we decided to give spiralling 1P math with 3 act tasks a try.

Each day or two I would  introduce to a new 3-act math problem (read Teaching with 3-Act Tasks) to solve with students. We would use that to stimulate wonderings and finally narrow down to a particular goals I wanted to cover.  Each of these lessons is taught with a 4 part math lesson (From Kyle Pearce) which always has students working on solving problems on their own FIRST, and then we step in and teach skills (“math teachery” way) after.

We did not teach within units. We mixed up our 3-Act tasks and problems throughout the semester.

I kept a list of all lessons, and order I used, along with any resources like blog posts, video files, handouts, etc. I wanted to share that list below.

Spreadsheet design was by Kyle

The spreadsheet shows for each day,

  • the strand we covered,
  • the learning goal (LG – for my assessment sheet),
  • the topic, notes for planning,
  • the inquiry lesson portion (3-Act math problem(s))
  • connections to other strands (a place for me to remind myself to tie this piece to other strands)
  • the consolidation/practice resources/links
  • other resources like blog posts, handouts, links, tweets, etc.

You may notice the bright pink row. These are our assessment/mastery days. We had one whole class each week for this.

The first half of an assessment/mastery day class was handing back of past paper assessments that look like:

Assessment

Each one consisted of 4 questions that covered the learning outcomes of the last week or so.  I wrote feedback for any question that weren’t completed perfectly. They were to read the feedback and re-do those questions.

I let them know that everything counts…..I consider all our conversations, my observations and anything they hand in for their grade.

Also during the first half of class students worked towards upgrading their skills. They access their customized spreadsheet which shows their achievement on each of the learning goals. They choose a learning goal to upgrade. Based on their prior achievement they are given another task to try. After I assess this new task I go and change the mark for that learning goal.

Both Kyle and I have written posts on this sheet a few times. (here, here, and here). An idea we extended from Alice Keeler.

We spend a good chunk of time working at getting better on our skills always promoting growth!

The last half of the class we do this week’s paper assessment (that looks like the one above). I mark it and give it back so that next Tuesday we can do that all over again.

Here are some benefits I have noticed from both spiralling and teaching through problem solving:

  • Almost no need to review at the end of the year. We reviewed all through.
  • Students see how math connects together. (Proportional reasoning shouldn’t stand as a lone unit when you have linear relations and algebra to teach too!).
  • Students were more confident in math than I’ve ever seen them. (And for 1P’s too!). When teaching in units, students know that whatever problem we will solve today HAS to do with what we learned yesterday. When we teach through spiralling students are always wondering what math they can use to solve the problem at hand. My students became great at risk taking! They would try! How many times has it been where we give a new problem to our students they complain that you haven’t shown them how to do this. My students were given new problems everyday and they became great a trying strategies. Whiteboards help immensely with this too!
  • A time saver! You may think that I would run out of time teaching this way…..I couldn’t possibly teach through problem solving and still cover everything, let alone booking a whole day dedicated to growth EACH WEEK! We had lots of time. Since each lesson tied multiple expectations and learning goals together, we could cover more in one lesson than we could in two lessons the old way. The growth/upgrades each week allowed students to practice skills from all over the course. Around mid-term time I gave my students an old final exam to see how they would do, and they did great!!! I was amazed. We still had half a semester to go!
