Quadrilateral Properties w/ Card Sort

I changed it up this year and introduced these pages before my quadrilaterals flip-book (you can find in previous post ). I had students tape down properties of parallelograms, rectangles, rhombi, and squares on the left side of their notebook and had them tape down properties of trapezoids on the right side.

I told students, every day that we go through the different types of quadrilaterals, I want you to reference this page and write down key information that will help you remember. This will be your own personal "quadrilaterals cheat sheet" and its sole purpose is to help you come up with your own way to remember the properties.

After the unit was done, I glanced through students notebook and wrote down the most common notes. The pictures below are what most of my students ended up writing down in their INB. I did not provide students with any information to write down. 

After students taped down the blank properties in their INB, I had students complete a quadrilateral card sort. I told students to sort the cards and write down a short paragraph on why they chose to sort their cards that way. 

The following are the 3 most popular categories that students chose to sort their cards.

Popular Category #1: 5 different groups

Group 1: Angles on cards J, F, P, G, H, and C are all congruent.

Group 2: Angles on cards N and L are supplementary.

Group 3: On card A, only half of the diagonals marked.

Group 4: On cards I, D, O, and M, the angles marked are supposed to represent ninety degrees.

Group 5: On cards E, K, and B, the diagonals are congruent.

Popular Category #2: 2 different groups based on angles and diagonals

Group 1: On cards C, D, F, G, H, I, J, L, M, N, O, and P, angles are marked in the picture.

Group 2: On cards A, B, K, and E, diagonals are marked or given in the picture. 

Popular Category #3: 2 different groups

Group 1: 
Students placed these cards in the same group because they are all part of the parallelogram "family."

Group 2: 
Students placed these cards in the same group because they have their own family since they do not have two pairs of parallel sides. 

This was my first card sort activity where I allowed students to choose how they wanted to sort the cards. Definitely going to be making more card sorts like these in the future!

Here are the files that I used if you would like to use!

Anchor Chart for Surface Area and Volume of Prisms

Today, I decided to create the following anchor charts for my geometry resource classes. The purpose of creating these charts was to give students an additional tool to support instruction and to move the students towards achieving success with finding the surface area and volume of prisms. I'm going to ask the librarians at my school to print these out as half size posters and laminate them for me to hang them up around my classroom for students to reference. It's faster for me to create this anchor chart digitally than to handwrite it.

This is my first year teaching a geometry resource class and I did not realize how much assistance and supplemental aids some of these students need. My resource classes are very small and one class has 8 students and the other class has 5 students. Last month, I learned that my school district is getting rid of these geometry resource classes so this has me scrambling to come up with ways for these students to be successful in my on-level classes for next year. I think I am going to create these charts for every topic in geometry and have them spiral bound for students to reference.

Any feedback or suggestions are welcome since this is my very first "digital" anchor chart.

Pi Day Card

I absolutely LOVE receiving any sort of notes from students so I decided to make a "Happy Pi Day" card for students to write to their favorite teachers. Best part of this was that students asked if they could write to multiple teachers!

Note: I added "FROM" to this since I had a lot of students not sign their name.

Feel free to use: Happy Pi Day Cards

Quick Error Analysis Practice

I am always in the process of changing up my lesson plans last minute. If my principal were to walk in my classroom on Wednesday, my agenda and activities would not match up with my lesson plans for the week. For example, I did not like the way my lesson was going with some of my classes during my quadrilaterals unit. I decided to rig something up last minute during my conference period and try it out with my remaining classes.

This activity was easy to make since all I had to do was solve the problems either correctly (truth) or incorrect (lie). Students had to separate the cards and justify their reasoning on the card stock. I thought that students would easily catch my errors but, students took their time and slowly examined each card.

I had a total of 7 "truths" and 5 "lies" and this threw some students for a loop because students automatically assumed that there would be an even amount of "truths" and "lies."

If you haven't already tried some error analysis practice, I highly recommend it! It is easy to create since you could use an anonymous student's work or you can write it out yourself.

Here are the blank cards that I used for this activity:

2016-2017 Right Triangles Unit

Here are a few glimpses into my right triangles interactive notebook pages. I created several new pages this year and thought I'd share! :)

Day 1: Pythagorean Theorem

We went over this new flip-book that I created over the summer. We broke it up into separate sections to not make the lesson seem so long.

Some of my classes went through these Pythagorean Theorem Real World Applications Task Cards.

My resource classes made Rockstar Math Teacher's Pythagorean Theorem Real World Situations Poster.

Overall, this was a GREAT block day! I allowed students to do a "Pythagoras Project" to replace 2 of their lowest homework assignments. Here are two examples of students who opted to do this project.

Day 2: Converse of Pythagorean Theorem
This is also a new foldable that I created over the summer. I re-made Erin Atwood's Converse of Pythagorean Theorem Slider (Click Here For Her Free Slider on TPT).

Afterwards, we completed my Converse of Pythagorean Theorem Card Sort (that you can find here). Students showed their work in their interactive notebook.

Day 3: 45-45-90 Triangles
I have used these next couple of foldables for the past 2 years since I love them so much. You can find my original blog post when you click here. 

Day 4: 30-60-90 Triangles
These are also old foldables that I have used in previous years. You can find my original blog post when you click here. 

Students then completed my Special Right Triangles Color By Number (click here for original blog post). I found some typos that I will be fixing soon so I had some students choose their own colors :). Here is one example of the "correct" color by number and one where student chose the colors that they wanted to use. I may modify it in the future so students can choose their own colors.

Day 5: QUIZ (BOOO!!!); Students did well (YAY!!!!)

Day 6: Trigonometric Ratios
I have also used this foldable for the past 2 years but I am going to change up the right side of the foldable. I would rather them practice finding missing sides and angles of each given ratio. Here is a link to my original blog post (click here). You can find the homework and warm-ups that I gave students on TPT (CLICK HERE).

After foldable, students had just enough time to work in pairs to complete this Trigonometric Puzzles Activity that I made last week! LOVED IT!

Day 7: Angle of Elevation and Depression

Right Triangles = LOVE! I am excited to share some of my resources that worked well with my students. If it works well with your students, please let me know! I always love to hear feedback and/or any other resources that you use with your students.

Here are some of the foldables/files that I used throughout my right triangles unit: 

I have the links to all of the other foldables in previous blog posts.
