Algebra 1 Unit 2 Interactive Notebook Pages | Relations & Functions

Here are the notes I used this year for the 2nd unit of Algebra 1:

pictures_Page_01

Day 1:
We started off the unit with a classifying variables sort. This was a good way to jog students’ memories about their prior knowledge, and it also served as a jumping point into domain and range!
pictures_Page_02

From there, we went into what a relation, domain, and range is, and how it relates to independent and dependent variables. pictures_Page_03pictures_page_04.jpg

We then made the distinction that there are two types of relations, discrete and continuous, and we must pay attention to context to determine what type of relation we have. pictures_Page_05

From there, we started to talk about all of the different ways we could represent a discrete relation, and how we find the domain and range from each representation.  We used this foldable, which went over great with the students.  They caught on super quickly, and they mentioned that they liked having one example to do together, and one to do on their own for each representation. pictures_Page_06pictures_page_07.jpg

Day 2:
We started off with a word problem to review domain and range in a (discrete) relation. pictures_Page_08
From there, we filled out a Frayer vocabulary model for functions, to make sure that students really understood what they are and aren’t. pictures_Page_09

Then, using the definition for function we just wrote down on the Frayer model, we made a cheat sheet to refer back to that tells us all of the different ways a relation (discrete or continuous) would NOT be a function.  pictures_Page_10

We practiced classifying functions using a card sort from Amazing Mathematics.  Instead of cutting and pasting, we decided to color-code instead! Love it! (In the words of one of my students, this is the page that has “fourteen thousand graphs.”)pictures_Page_11

We then filled out another cheat sheet, this time for domain and range of continuous functions.  Students reasoned together through the inequalities and we talked about what a bound actually means (we used a lot of basketball references). pictures_Page_12
We practiced finding the domain and range for continuous relations (as well as determining whether or not they were a function), using the following set of notes.  PS: It took me a LONG time to figure out how to make a parabola or a trigonometric wave using Microsoft’s shape tools.  I feel overly proud of this set of notes! You can download them herepictures_Page_13pictures_page_14.jpg

Day 3:

We began with a recap warm-up on domain and range for continuous relations. pictures_Page_15
To make sure that students didn’t forget about discrete relations, we went back and did more practice with determining their domain and range, and also stating whether or not the relations were functions.  pictures_Page_16pictures_page_17.jpg

Day 4:
We started off with a reference sheet on function notation and how to read/say it. pictures_Page_18
From there, we did a lot of practice with function notation.  pictures_Page_19

Inside this set of notes, we really emphasized interpreting what we were being given in a problem (input or output value) and what the problem was actually asking us to find (input or output value), before starting the problem.  This helped students from making a lot of careless mistakes.  After we practiced function notation in both directions (evaluating a function, and solving for an input given the function’s output), we mixed up the problems and even threw a few variables and function compositions in there!pictures_page_20.jpg

Day 5:
Recap warm-up on function notation.  Problems 5 and 6 both spurred amazing conversations about order of operations. pictures_Page_21

After doing this recap warm-up, we did my function notation mystery sum activity, which was a blast.  It encourages students to collaborate together and it’s really high engagement each time.

819

From there, we continued talking about function notation, but now in terms of a graph.  Interpreting what the function notation was telling us was such a huge part of the previous day’s lesson, that I wanted to see how they could do when we attached a context to the problem. pictures_Page_22

Inside, we worked on graphing functions, and using the graph to find an x-value.  Some students preferred solving for x, but others were impressed by my tracing over on the graph method.  To each their own–that’s the beauty of math, in my opinion. pictures_Page_23

Day 6:
Recap warm-up over function notation with graphs, and then we reviewed for the test. pictures_Page_24

Day 7: Test!

Algebra 1 – Unit 1 INB Pages | The Foundations of Algebra

Here’s what went into our INBs for the 1st unit of Algebra 1:pic_Page_01

Day 1:
We glued in a reference sheet for the real number system. Our textbook uses I for the set of irrational numbers.  I went with the same notation this year, but I think I’m going to go with R-Q for next year, since I is used for imaginary numbers, later on.  pic_Page_02

To practice working with these definitions, we did a real number system sort, which I found from Amazing Mathematics! My students enjoyed doing it, and it spawned many great conversations about the difference (however subtle they may be), between the sets of real numbers.

pic_Page_03
Real Number System Sort from Amazing Mathematics 

For homework, students did this Always/Sometimes/Never sort, which is also from Amazing Mathematics. They were given about 20 minutes in class to begin their assignment, and then had whatever was left as their take-home assignment for the night.  This one was even better than the last card sort, in terms of spurring student conversations.  Students were justifying with counterexamples and providing fully flushed out reasons for where each card should get placed.  It was awesome!

Always/Sometimes/Never Sort for Real Numbers from Amazing Mathematics

As a note, we also keep a binder for the class which holds extra handouts, like additional reference sheets and homework assignments that don’t go in the INB. My favorite reference sheet that didn’t go into the INB was this real numbers flowchart that I made.  The day of teaching my lesson on real numbers, I noticed that using the “Venn diagram” approach wasn’t meshing well with some of my students.  That afternoon, I went home and made a flowchart handout that they could refer to, in addition to their INB pages.  Next year, I think I’ll just use this flowcharts in a mini-book format for notes, instead!  I found that students started making more connections about the sets each number belongs to (i.e. not only is a number natural, but it’s a whole number, and an integer, and a rational number), and students were able to remember the questions they need to ask themselves when determining the best classification for a real number.

Day 2:
We started off with a recap warm-up on the real number system, which we covered the day before. pic_Page_05

From there, we did a translating expressions sort, also from Amazing Mathematics.  (Can you tell I love her sorts?!).

pic_Page_06
Words into Math Sort from Amazing Mathematics

From there, we used our key words and started defining what a variable is, and what an expression is. pic_Page_07pic_Page_08

For homework, students did the following problems.  They had about 15 minutes of class time to get started.  We color-coded “turn-around words” in pink, “parentheses-words” in green, and “equals words” in blue.  Students marked the page in highlighter before beginning to translate the expressions.  They mentioned that this made the process much easier for them! pic_page_09.jpg

Day 3:
We began with a recap warm-up over translating expressions.pic_Page_10

From there, we talked about evaluating expressions and also reviewed the order of operations.
pic_Page_11

From there, we discussed the properties of real numbers and students made up their own examples for each property.  pic_Page_12

For in-class practice, students did the a properties of real numbers puzzle from Lisa Davenport.  A student volunteered to glue it into my notebook.  Notice the lack of glue?  Notice the crooked edges?  It was a very sweet offer, but I’m I don’t think it’s one I’ll be taking again any time soon. IMG_1668

Day 4:
We started with a recap warm-up over evaluating expressions and identifying properties of real numbers. pic_Page_14

Next we took notes on combining like terms and the distributive property, cutesy of Sarah at Math Equals Love.pic_Page_15pic_Page_16pic_page_17.jpg

Day 5:
Recap warm-up over distributing and combining like terms. pic_Page_18

What is a solution?  What does it mean to be a solution?  What does it look like? pic_Page_19

Up next, we focused on solving and verifying solutions to 1-step and 2-step equations.  I’ve found that verifying a solution is a skill that students struggle with more than solving (at least in Algebra 1), so I wanted to make sure it got emphasized. pic_Page_20pic_page_21.jpg

Day 6:
We filled out a foldable for solving 2-step equations.  Those pesky fractions are going to be our friends by the end of today!

Day 7:
Recap warm-up over solving equations. pic_Page_24

Day 8: Review

Day 9: Test!

 

 

My No. 1 “Teacher Hack” For Interactive Notebooks

Making things for interactive notebooks can be tedious, at times.  If you’re like me, you use a composition notebook so students will (hopefully) resist the urge to tear out pages for scratch paper.  The issue with composition notebooks, however, is their sizing.  A full sheet of paper is much too large to fit, but a half sheet makes the page feel a bit empty.

Also, unless you want to make everything from scratch to perfectly fit in your interactive notebook, you’re a bit stuck on what to do to get full-sized materials you may have used in the past to fit.

My hack: print any normal sized paper at 80-85% the size and, after cutting out the paper, it will fit PERFECTLY into a composition interactive notebook.  Use this hack to make the world your oyster.

Here’s how to do it:
1.  Make sure your document has been saved as a PDF.
2.  When you go to print, select the following setting:printing setup

Rule of Thumb:
If the margins on the original paper are 1″, print at 85%.
If the original margins on the paper are .5″, print at 80%.
If the original margins on the paper are at .25″, print at 75% (not common).

Here’s the difference it makes:

This has saved me a TON of time making interactive notebook pages, and also allows the writing space to be much larger for students.  Sometimes a half-sheet can be cramped.  Hopefully this teaching hack can help save you a ton of time, like it does for me!

Class Info Stations Activity for Day 1 of Class and Algebra 1 Syllabus

I read a lot of blog posts last week about people’s first day plans, since that was a prompt for one of the #SundayFunday challenges.  I can’t remember who I got the idea from, but someone posted about doing a class syllabus stations activity and my gears started turning.

This year I updated my syllabus a bit. It’s twice the length that is has been in the past (I love nothing more than 1-page documents), but I felt the need to add more information to communicate to parents.  I’m hoping that this syllabus will give parents a better understanding about what their student is doing each day in my class.

pictuers_Page_1pictuers_Page_2pictuers_Page_3pictuers_Page_4

Students will work in groups of 3-ish moving station to station to answer the questions from each station’s card.  I am going to have students record their answers on a scratch paper and, once everyone is done, we will compare answers as a class and see how they did.

Solving Literal Equations “Connect 4” Activity {Student Approved} FREE DOWNLOAD

Recently, I reached out to the MTBoS looking for fun ideas for practicing solving literal equations.  I had searched pretty thoroughly to find any pre-existing activities on the internet, but there wasn’t a lot available.  On top of that, what was there, required way more pre-existing skills (SO MUCH FACTORING!) than my Algebra 1 students currently had a month and a half into the school year.   Unfortunately, the MTBoS and I were pretty stuck. feed

Farther down in this Twitter conversation, however, it was mentioned that someone recently used BetterLesson’s lesson for teaching literal equations.  At that point I had already taught the lesson and most of my students caught onto solving them quite quickly, but I still was looking for a fun way to get a bit more practice in.  While exploring what BetterLesson had, I found this worksheet  that gave me inspiration for a game I could play with my students.  After a little bit of brain-storming, I created what I’m calling a Connect 4 Activity.  Essentially, it’s BINGO, but 4×4 instead of 5×5.

How to play: 

  • Before game: print enough game cards so each student has one, and cut apart the 16 problems.  I fold the problems in half (the problem number to the inside) and put them into a plastic bin.  (When printing from your computer, make sure it says “print double sided, flip on long-edge.”)
  • To start off the game, each student gets a game board, on which they randomly place the numbers 1-16.  Students then pull out a piece of scratch paper, where they will be doing their work.
  • The teacher brings the plastic bin containing the 16 equations around the classroom, letting a student volunteer pick a problem at random. (They LOVE getting to pick!)
  • The teacher then places the problem under the document camera (or writes it on the chalk/white-board if you’re at a low-tech school) for students to solve.
  • After all students have solved the problem, discuss the solution as a class.
  • Once all students are silent, the problem number is revealed for students to cross off on their game card. (The excitement levels usually explode at this point, hence the moments of silence in between.)
  • Repeat for as much class time as you have available, or until all 16 problems have been solved.
  • Each time a student gets 4 in a row, they bring up their card and their work for inspection (they showed their work and corrected any mistakes for each problem), and are allowed to choose a small piece of candy (Jolly Rancher, a Starburst, etc.).

Reasons why I LOVE this game:

  1. It is super easy to set up and is so adaptable for other topics.  This has probably been the lowest prep activity I have made for my students, yet it has been one of the most successful.
  2. Students felt much more confident about their skills and were able to get nearly-instant feedback about how they’re doing.
  3. Students LOVED it. The class begged me to continue letting them play the game through passing time.

(Updated September 2017)
This year I wanted to find more ways to practice literal equations with my Algebra 1 students.  We teach literal equations the week before Halloween, so I wanted to make something really fun and “Halloween-y.”  I made a Carving Pumpkins activity that’s self-checking and SUPER fun!  I couldn’t wait to try it out, so I gave it to my Algebra 2 students mid-September (patience never was my virtue) since they review literal equations in their first unit.  Students though it was fun, and they also found it really comforting that it’s self-checking.  To quote a group of boys, “this is super dope, we should do this for all of the holidays!”

Students are given 12 literal equations to solve for a specific variable.  Depending on what their answer was, they “carve” color the corresponding pumpkin in a particular way. In the end, each of the pictures should end up looking the same, as far as the color and carvings go.

I’ll be making more activities, and will update the post!

 

 

Systems of Linear Equations and Inequalities Unit Interactive Notebook Pages (Algebra 1)

Here are the notebook pages my students completed on Systems of Linear Equations and Inequalities during the last school year.  Let me know if you would like me to post any of the documents I used.  Thoughts or suggestions on how I can improve interactive notebooking?  I started this as my work sample for my MAT degree so I am still very new to the world of INBs/ISNs.  I’m not entirely sold on the Left/Right hand page for in’s and out’s.  I understand the concept behind it, but I also don’t believe in forcing notes to be in a specific format for the sake of being in this format.  Anyway, this was my first take on my “INB” inspired notebook…not fully an Interactive Notebook, but on its way.
