This activity is to be used as a discovery-based introduction to similar triangle theorems. Students will each be assigned a number 1, 2, or 3 (I use cards for this or counting off). They will get into groups by number and work on their station number. Students will follow a set of directions that have them construct a similar triangle either using two angles, a side-angle-side, or three sides. This will help students conceptualize why similar triangles are created from just 2 or 3 measurements

This is a unit project to go along with compound probability. Students in class will make a carnival game that involves compound probability. I,e. roll a dice and toss a coin, choose a card and pick an animal, etc. Students will design their game, make their game, calculate the probability of winning their game, test their game, etc. all on a project packet. Students will need some time in class designing their game boards, etc. On carnival day, we invited other classes to come in and play our

Students can make a fun foldable with an example and work space to create basic geometric constructions using a straight edge and compass. I had students glue the foldable into their Interactive Notebook!

This is a full year of short CFA assessments. They are graded on a 1-4 scaled. I have students do them after we learn a new topic. The CFAs are mapped to the geometry standards for Common Core. Each CFA has at least two versions for retake purposes and a lot of them have 3 versions. I allow students to retake them to ensure they are learning the standard. They are on quarter or half sheets to save paper. Every CFA document is in Word so it can be edited for your needs. Here are the topics of the

How does scale factor change perimeter and area? I had students graph two triangles with a scale factor of dilation of 2. Students looked to see how the area and perimeter are affected when a scale factor is applied. They then make conjectures about the change in perimeter and area to apply to additional examples.

Students receive a handout describing an expository essay. I listed topics that students could choose from (what we had covered so far that year in math). Students write an expository essay explaining how to do something in math. I also provide a full example of an expository essay on how to add mixed numbers for students to see. This is a great way to get students writing in math! It also helps with 21st century skills. I showed students how to insert equations, objects, etc. in Microsoft Word

This file contains an ActivInspire flipchart file to teach transformations of quadratic functions in a student friendly way. Print out the notes 3 slides to a page to make the fun interactive note foldable for students to glue into their notebooks and take notes as you go through each slide as a class. Also contains a PDF version of the file to be printed out for students. Have students help you discover the different transformations. All can be edited to fit your needs!

Students practice vocabulary by playing a fun game of truth or dare. Print out the cards on card stock, fold them and glue the inside to make the playing cards. I made one set for each group in my class. Have fun with the vocabulary! Editable Word Doc Vertical Angles Supplementary Complementary Adjacent Linear Pair Angle Bisector

Print off the posters containing all of the properties of transformed quadratic equations and hang them around the room. At the start of each round, students must pick a poster property to stand under. Then, display a new quadratic function. As a class, they need to determine which transformations apply to that function. If a student is standing under the poster that has an applicable transformation, they are eliminated and must sit down. PDF and Promethean Board Flip Chart files included Answe

A Promethean Board lesson for writing linear equations in slope-intercept, point-slope and standard form. Notes are color coded and includes a flow chart to help students write equations. I have a PDF of the slides and the actual Flipchart lesson that can also be imported into a Notebook file.

This is a fun way to help students review for the PARCC test. I copied the questions from the PARCC practice test (18 different questions). I printed 5 sets off on different colored card stock. The students will be in 5 groups and work on answering the questions. I made a ActivInspire flipchart that has the same 5 color cards to be dragged into that group's column as they complete each question. I reward the class with 20 seconds of free time for every question the groups get right as a whole cl

This lesson contains 7 unique station activities for practicing volume. There is a student worksheet that goes along with all of the stations. There's a second version of the student worksheet that has missing information for students to fill in as they work through the station (this holds them accountable for moving from station to station and not just working on problems with their packet). All items are a word document in case you would like to make any adjustments. Preparation: Print one se

This is a fun little booklet for the kids to take notes in as they are introduced to graphing quadratic functions. Print the booklet pages back to back and have students cut the page into thirds to create the booklet. Give each student a cover page for their booklet. Also included is the ActivInspire Flipchart to go along with the lesson.

I created this as a final project for my 7th graders. This replaced a traditional written assessment. Students had two class periods to work on their interview booklet. They were to research, review, study and answer questions over the main topics we did that year. On the last day of class, students were called back for an "interview." They were not able to interview if their booklet wasn't 100% complete. At the time of the interview, they drew a topic out of the cup and then I questioned them a

This is a summary lesson that ties together the unit on quadratics. Students solve a quadratic by factoring and the quadratic formula to find the x-intercepts. They also identify important parts of the graph (aos, y-int, vertex) and graph their function. This helps them see how all of the pieces are related. I use it as a partner quiz. Each pair needs an 11 x 17 copy of the poster (question page). Print off enough copies of the equations (6 different ones) and give one to each pair. This is th

This is a word document that can be altered for your area. I had students spend a period in the computer lab researching different local population densities. Students research the town area and population and then calculate the density. They had a lot of fun finding out about local areas! There area a few follow-up density questions on the second page from the Galileo Test Bank.

Students use spaghetti noodles to explore the Triangle Inequality Theorem and the Triangle Angle-Side Relationship Theorem. Each group needs 4 sticks of spaghetti that they cut to different lengths using a ruler and scissors. This is a Flipchart file also converted to PDF for a slide show.

Have students cut out the figures, definitions and names to math up the vocabulary! Great for a review on the vocab.

This is a fun homework packet to accompany transformations on the coordinate plane unit. Students graph their own picture and then apply various transformations to their original picture. Broken down on a day-by-day basis. Translation, Reflection, Rotation and Dilation. Gives a break from traditional textbook style homework problems! Directions ask students to add color to their graphs and glue them all on a larger paper. My students really liked this! Their projects came out great and even my

Volume scavenger hunt includes prisms, cylinders, prisms and cones. Hang the question cards around the room. I then gave each pair of students a starting card (this way they all start in different places). They solved their question and then found their answer around the room. The new question is next to the answer they just got. I had envelopes under every question with a bunch of copies of the new questions. Students took a copy, glued it into their Interactive NB and then solved the questio
