### STEMsgiving Math Samplers AND a GIVEAWAY!

Happy Thanksgiving! At this time of year, our thoughts turn to all of the things we are thankful for - our family, and friends, and even our students. A group of STEM teachers and I got together and thought and thought about how thankful we are for you - our STEM colleagues!

We worked and worked and put together some really great STEMsgiving samplers for you to try out at a fabulous bargain - these samplers are set to be purchased at half price - WHAT A BARGAIN!

After the linkup - don't forget to keep reading to the bottom of this post to get a chance to enter to win a $50 Teachers Pay Teachers Gift Card Giveaway!!!

### Resources to practice Trig Special (Convenient) Values

This happened in calculus class the other day...we found the derivative of something involving a trig function and then had to find the value of sin (π/4) in order to finish the problem. I said ok what is the value of sin(π/4) and I got wildly differing answers including 0 and 1. That drives me absolutely nuts...it shows absolutely no understanding whatsoever. Don't get me wrong, I'm not blaming anyone...it wasn't the precalculus teacher's fault - I'm the precalculus teacher this year and I totally get the struggle!

So, I searched and found the best online game (free!):

Here is the website where it came from:

Unit Circle Game

Students play this online. (My students used their iPads and it worked fine.) Students practice putting the radian angle measure in the correct place. In addition, they practice putting the coordinates in the right place. The website times you...you should have seen the competition going on in my class for the best time :)

But, I know the students need more practice...see the linkup below for even more options.

### Fun Halloween Secondary (Middle and High School) Math Activities

The Secondary Math Classroom can be fun too!

Even our best high school students have a little trouble keeping their minds on math sometimes :)

Here are some awesome suggestions for activities for students in secondary math. Feel free to link your activity.

### Using Classkick in the High School Math Classroom

Do you integrate technology into your classroom? Are you a 1:1 iPad school? If yes, do you wish you could find an app for your students to use that caused them to say, "I love this app!" And "Can we use this app every day?"

Let me tell you about the app Classkick. When using this app, you can see everything your students are doing on their iPad in real time. You can give them feedback in real time. Best of all, you can give them a virtual sticker if they get the problem correct!

Here is a screenshot of a problem I gave to my calculus class recently.

Notice the problem is right in the Classkick app. I typed the directions in the app and then imported a picture of a problem I wanted the students to do. [note: there is no equation editor in Classkick as of yet.]

Here is a screenshot of one of my students' work that he did right on the iPad.

Here is a screenshot of the sticker he got when he got the problem right and you can see where I wrote Good on his work.

After briefly being creeped out when they realized I could see exactly what they were doing, my class worked diligently on the three problems I gave them. I know it sounds completely unbelievable, but the all worked and were completely engaged. They all wanted my attention RIGHT NOW,

The best part for me was that I could correct errors as they were happening. Kids could ask me a question virtually and no one else had to know. I could tell immediately who still needed practice. It was great ��

Beware: Once you turn the students loose with this app, their answers will come quickly and you need to be ready. Once someone gets a message from you, or a sticker, they will all be calling out for you! Classkick provides a feature so that students can virtually raise their hand for help or ask you to check their work. They can also ask another student for help...however I haven't experimented with that feature yet because I was a little worried about what one student might write on another students' screen. Depending on your class, this might be a great feature for you.

If you are interested in learning more about Classkick, here is a link to their website: Classkick

[One thing I forgot to mention...Classkick is ABSOLUTELY FREE and students join your class by entering a class code...no user names or passwords to remember!]

### Snippets of Video on You Tube for High School Math

This post will be a compilation of video snippets I find on You Tube or other places online that are helpful in introducing or teaching high school math. These are not Khan Academy type videos - they are fun snippets that you can insert in your lessons when a laugh is necessary :)

1) Introducing Proof - How to Prove a Mathematical Theory - by Scott Kennedy for Ted Ed - 4:38

2) Volume of a Cylinder - Phineas and Ferb - 0:15 - Phineas and Ferb discuss the formula for finding the volume of a jar of jellybeans.

3) Pythagorean Theorem - Simpsons on the Pythagorean Theorem - 0:08 - Homer states the Theorem incorrectly.

4) Vectors - Vector from Despicable Me - 0:59 - Vector introduces himself to Gru

5) Newton vs. Leibniz - Merry Newtonmas - 1:09 - Big Bang Theory - Sheldon wants to hang a Newton ornament on the tree.

6) Crickets Chirping - The Jiminy Conjecture - 2:47 - Big Bang Theory - Sheldon counts the number of chirps of a cricket and is able to determine the type of cricket.

7) Speed and Velocity - They Might be Giants - Speed and Velocity - 1:50 - from They Might be Giants - cute video and song that will be stuck in your head :)

8) Newton vs. Leibniz - Fun Cartoonish Video about the Calculus Controversy - 7:46

9) I Will Derive - Fun Song Parody called I Will Derive - 3:16

10) Pi on Phineas and Ferb - Pies Recite the Number Pi on Phineas and Ferb - 0:17

11) Triangulation on Phineas and Ferb - a fun song about using triangles to find the height of a building - Triangulation - 0:44

### Teaching Analyzing Functions in Pre Calculus or College Algebra (and a FREEBIE!)

This year I am teaching Pre-Calculus - Yay :) I have taught the course before, but it has been several years ago. We are going to be working on analyzing functions soon, so I thought I might do a round up of activities/lessons/worksheets that I have found that look like they might be good to use in class.

1)

__Analyzing Functions from Graphs and Tables__- This is my own set of worksheets that I made this summer once I knew that I was going to be teaching this course.

This set contains 7 worksheets.

Worksheets 1 and 2: Students will work with a single graph and answer questions about function values, where a function has a maximum or minimum, what the maximum or minimum value is, and where a function is increasing or decreasing.

Worksheets 3 and 4: Students will be given two different functions on a single graph. Students will work on finding values of things like f(x) + g(x); f(x) – g(x); (f(x))(g(x)); f(x)/g(x); and combinations of these functions.

Worksheets 5: Students will be given two different functions on a single graph. Students will work on finding the value of the composition of the two functions.

Worksheets 6 and 7: Students will be given a table with values for f(x) and g(x). Students will use the table to find the value of the composition of functions.

Would you like to see a sample page from this packet? Here is a link to the first page [FREE] - if you find it useful, I hope you might leave a comment on this post or a rating on TPT :) FREEBIE!

If you like the sample page, here is a link to the full product on Teachers Pay Teachers. Full Product - Analyzing Functions from Graphs and Tables

2) Next up from my friend Jean Adams at Flamingo Math - Here is a Functions and Graphs Stations Activity. You can use this activity at the end of your unit - students love getting up and moving around the classroom!

3) Do you need help teaching function notation? Here is a link to a blog post from my friend Karrie at Mrs. E. Teaches Math How I Teach Function Notation. Need to follow up? Try this maze with Operations on Functions.

4) Need help with the composition of functions? Try these two activities:

A) from Janet Knox: Composition of Functions Cut and Paste

B) from Sandy Pinder (Weatherly): Composition of Functions Worksheet

Hope these help!
