5 Reasons Why You Need To Use Google Forms for Quizzes in Your Classroom

I don’t know what I would do without google forms! I have 150+ students this year and I’m teaching three different subjects. Google form quizzes have saved me! I recently made a google form quiz template that I will share with you at the end of this blog. Here are the reasons I love google forms for quizzes:

  1. TIME SAVER – Yes, you have to spend time making the quiz upfront, but the time you save on not grading the quiz is so worth it. I love that the quiz grades itself. You can even send students their results by email. You can share a copy of the quiz with other teachers. They can take the copy you give them and edit the quiz to work for their classroom. It would be great to alternate with a fellow teacher on making the quizzes. Again…big time saver! Once you have made your quiz, it automatically saves in your google drive. Now you have it for next year!
  2. ANALYTICS – When the students are finished taking the quiz, you can view the data! At the top of the google quiz, there is a tab for responses. In the response tab, you can view the summary, individual questions or individual students. You can’t get this from your paper assessments! Well, you can if you feel like spending a million hours figuring it all out! The data is very helpful! The picture below shows some data from one of my recent Algebra II tests. Take note of the most missed question! I love that I get to see what the students struggled with the most. This helps me with planning.goo2
  3. TEACHER ERROR – Do you ever make mistakes? I do! If you make a mistake on the quiz, just go fix it. If the students have already taken the quiz and you made a mistake and forgot to mark an answer in the answer key, then fix it. The google form will automatically make updates to the grades for each student. There are many times when my first period class will notice a grammatical error. I’ll fix it before the next class. It updates and saves automatically.
  4. GOOD FOR SUBS – When I know I’m going to be gone, I love to plan a quiz. No papers to copy, grades will be automatically generated and the sub really doesn’t have to do anything but keep an eye on the students! I hate being absent because it seems like it’s more work than it’s worth. Now I can take a mental health day and feel good about what the students have done while I’m gone.
  5. SIGN OF THE TIMES – We can’t hide from technology. I’ve been teaching for 32 years and I want to be up on what’s out there! Some teachers don’t want to mess with google forms because they feel like it will be too complicated. It is not complicated! Dive in! You can handle it. It just takes practice. I’m leaving you with a quiz template. Make it  your own. You will love it once you’ve become familiar with it.

*You will need a gmail account to create a google form.

Using Desmos in your Class Blog/Website

My BlogI love Desmos, so when I discovered how to use HTML code to add a desmos practice graph on my blog, I was ecstatic. If you are not familiar with Desmos and you are a math teacher, you need to visit the desmos.com site!

I use my class blog for many things:

  1. Lesson Plans
  2. Syllabus
  3. Math Links
  4. Class Announcements
  5. Videos
  6. Quizzes and Tests
  7. Classwork
  8. Homework
  9. Anything else I can think of!

I love having a blog because it saves me paper, but the best part is when I have a sub. I put the plans on the blog and the kids know to go to it and find their work! It’s so nice not to rely on somebody to give the students the work. No excuses!

Recently, I was trying to figure out how to do something else with Desmos and discovered how to put a graph right on my blog. You can view it here if you’d like.

So if you are ready, let’s add a graph to your site!

As a teacher, if you haven’t created a Desmos account, that would be the first thing you should do. Next, create a graph that you would like to use or for the purposes of practice, use a blank graph. Go to the share button in the top right corner of the Desmos page.

Desmos 1

Click the share button. Copy the link (don’t click embed). Now you need to add some code to the beginning and the end of it, so it will work.

Type this: blog 4In place of the red sentence above, put the link that you copied from Desmos. You can play around with the dimensions of the height and width to fit you blog.


Now you need to know where to put this code. In the blog or website you use, find where you normally go to create a new post. There is usually a place to put HTML code. Here are two examples:

This one is from Blogspot:     blog 3

This one is from WordPress.com:      blog 2

Paste your code and save your changes. Go look at the post to see if it worked!

I hope you are as excited about this as I am. I love learning new things and I love finding things that will help my students. Please let me know how it worked for you! Best of luck!


Angle Demonstration


Patty paper has so many uses. One of the very first lessons in Geometry is a reminder of the different types of angles along with the definition of an angle. In the top left corner of the picture above, you can see that two rays are drawn on two pieces of patty paper. One ray is called CA and the other ray is called CB. The students can clearly see the definition of angle when you do this. When  you put the two rays together at point C, you’ve created an angle. From here, I get the students to make the different types of angles: right, obtuse, acute and straight. Finally, I get them to tape the acute one in their interactive journal. This is great for all ages and it gets the point across!

This lesson is a part of my Point, Line, Plane lesson that you can find in my store. All my Geometry lessons are in my Geometry Curriculum. You can see both resources below. Check them out!!!

Angel and Cowboy – Working with Inequalities

I came across the Angel and the Cowboy years ago. I did not create this, but I did add the bow tie. I love using this with inequalities. I have found it most useful when working with piecewise functions. The idea is that the hats and the face deal with graphing, the body is used for writing domain and range in interval notation form and the legs help with writing inequalities. All the pieces are related. Notice how all the Angel symbols are for NOT EQUAL and the Cowboy symbols are when things are EQUAL.

I found this slide from when I taught piecewise functions last year:

Let’s break this idea down a little further. If you asked your students to give the domain of only the left arrow, then they would see an open circle which is the angels face, so I call this an angel problem. The student would notice that the domain goes from negative infinity to -1. If you want the students to write this in inequality form, they would use the angel symbol and say: x < -1 or I allow my students to write: -∞ < x < -1. If you asked them to write the domain in interval notation form, they would write (-∞,-1). All symbols came from the angel!

Now let’s look at the right arrow. This is a cowboy problem (well not completely). The enclosed dot indicates that the problem is a cowboy problem, but since there is an arrow on the opposite end which represents going to infinity, this problem is also an angel problem. The domain in inequality form would be > -1 or -1 < x < ∞.  In interval notation you would write [-1, ∞). The second inequality answer and the interval notation answer contain both cowboy and angel parts. (Since you can never reach infinity, you can never equal infinity. That’s why I added the infinity symbol to the angel.)

Anytime graphing and writing inequalities is a part of a lesson the angel and cowboy can be useful. You may not need all the parts of the angel and cowboy. Interval notation is not taught until Algebra II in Texas, so when I’m using this in Algebra I, I usually just tell the kids that they will learn about the rest of the symbols later.

The solid and the dotted lines above the faces come in handy when graphing inequalities. If we are graphing y > 2x – 3, then the students will realize that the symbol came from the angel, so the line will need to be dotted. The one thing that the angel and cowboy do not help with is shading above or below the line. You could easily add the words above and below to the symbols on the legs if you wanted.

I’d love to hear from other teachers that have used this before. Let me know how you use it or how you have tweaked it. If you’ve never seen this before, I hope you will find this handy and you will be able to use it in your own classroom!

I’ve made a free poster of the angel and cowboy that is in my TpT store. If you are interested, please use this link and download this resource.     Cowboy and Angel Poster

Algebra II – Starting The Year

In Algebra II, it’s hard to decide how to start the year. I want to review, but I don’t want to keep us from moving forward. I need to know how much the students remember from Algebra I. My students were in Geometry last year. How much Algebra was incorporated into their Geometry class? I feel like my best bet is to begin by solving equations and inequalities. The activity that I will use, starts easy and gets progressively harder. The students will not be able to use a calculator because I need to know who REALLY knows how to solve equations without tricks or help. This activity is sold in my TpT Store:

 Solving Equations and Inequalities

Solving Equations and Inequalities

I really like this activity because there are options. I can make it fun by using the answer banks. The answer banks have the answers with an activity. A few of the activities have the students draw a picture. Another activity has the students fill in a movie title. There are progress checks along the way as well. I think that I will use the easiest page as a bellringer on the first day of class. I’ll have them work through as much as they can on the rest and send it home to be finished. I can use the progress checks as quizzes or as pages for their interactive notebooks. This resource will give me an idea of where the students are and will be a nice segway into solving absolute value equations which is what I plan on doing next.

Find What You Aren’t Looking For First!

I like to challenge my students. One way that I like to challenge them is through tricky diagrams and pictures. I don’t want every problem to be straight forward. I always tell my math students that sometimes you must find something you aren’t looking for in order to find what you ARE looking for. Since I teach 9th graders, I’m trying to get them out of the mode of thinking that all problems should be easy to figure out. I love watching them really think, but it tends to be frustrating when you have those students that want to ask you about every single problem or want you to stand at their desk and watch them so they can ask you questions. I’ve learned to give them a good 5 to 10 minutes of independent thinking time, then I’ll let them compare what they have so far with a partner. I’ll watch and listen to the conversations to gauge what to do next. If they are still struggling, I may give them a hint. Sometimes I’ll play the game where the only answers that I can give are yes or no. This will help them learn to ask good questions. Below are some examples of the types of problems that I’m talking about. If students get used to doing these types of problems, they will be excellent problem solvers and even though a problem may stump them, they will have the experience to know that if they stay after it, they can eventually figure it out.

This is from my Circles: Special Angles and Segments Resource

This problem is from my Law of Sines and Cosines Resource. 

I call this one, the Poodle Problem. It is in my Trig Unit.

This problem is from my Special Right Triangle Unit. 

The great thing about these problems is I’ve made them easy to grade. You know real quick if they’ve worked the problem correctly or not.

After a year of these types of problems, I’m hoping to see improvement in my student’s college entrance scores and EOC scores. I know that this will also help with their growth mindsets. I feel like this is definitely a win/win!
