Anyway, I'm rambling. Here are 3 posters I made about solving for x when angles are complementary, supplementary, or congruent. These come up again and again in Geometry. I think they look pretty, so I thought I'd share. Hope you enjoy!

### Seating Chart Grading Sheet

I hate homework. In the 9 years I have been teaching, I have done something different with homework. Homework quizzes, collecting homework, not collecting homework, etc. I could not figure out a good way to collect the homework, grade it, and return it in a timely manner so the students can see their mistakes and work towards corrected those mistakes.

In order to grade the homework, I created a grading sheet using my seating chart. When an assignment is due, I pick about 5 problems (sometimes less, sometimes more) to grade. When the students enter the classroom, they grab whiteboards, markers, and erasers. They also get out their homework that is to be checked. I then go through the problems I chose, asking my students to write their answer on the whiteboard. They are to wait for me before they display their answers.

Here's how it works:

Each box represents a student. The students name is written five times. Each time the name is written corresponds with a different problem I am checking. For some reason, I work bottom to top. This means the bottom name represents the first problem to be checked. If the student gets the problem correct, I mark out their name. If the student gets the problem incorrect, I circle their name. After checking each student's whiteboard, I tell the students the answer and we discuss the problem if needed. This process continues until all chosen problems have been checked. I assign each problem a point value, record the grades, and then file the grading sheet in my grade book. I also use this to check whether students completed the homework for a completion grade.

Pros: I really like this grading sheet for a couple of reasons. It is very quick to check the students' homework. I also can tell from the grade sheet with which problem the students struggled. With this, I can discuss the problem in more detail. I feel like before, when I typically graded homework paper by paper, I missed individual problem statistics. I also like that I can keep this paper with my gradebook. It also helps check attendance, so I can kill two birds with one stone.

Cons: With this, I can't check the students' mistakes since I'm just asking for the answer. Also, I have to be sure that the students are not just looking off their neighbors' paper. I need to walk around the room more and make sure the students have the correct assignment on their desk. Maybe having the students switch papers would help with this problem.

What do other math teachers do?

### Punch Cards

Thank goodness I'm done with graduate school! I now have more time on my hands to post!

This year, I implemented a new system in which the students could win prizes for their test scores. These prizes were given out based on different criteria with each test. With one test, the students who received a 100% were given prizes. On the next test, I gave the prizes to those students who successfully solved the two bonus questions on the test. For the third test, I told the students that those students who increased their score from the last test would be receiving prizes. Several students pointed out that they had received As on all of the test so far and had yet to receive a prize. "It's not fair!" they kept saying. After thinking about it, those students had a valid point. So I rethought my prize system. I had previously read Miss Calculate's blog post on her Punch Cards for behavior and liked the idea, but decided to use the Punch Cards for my prize system.

Here's the rules:

You are probably wondering about the Mandatory Retakes. Our tests are divided by target or concept with each individual target or concept receiving a grade. For the targets or concepts the students do not receive a 70%, the students are required to retake that portion of their test until they reach 70%. These retakes are completed during lunch.

So far, I like the punch cards. The kids were excited about the punches. I kept track of the number of punches so the sneaky kids couldn't rush to the nearest hobby store and purchase the same hole punch (I use a paw print for our mascot). I also had the kids write their names on the card in case the card was lost.

Here is the link to the rules. I have included both a PDF version and a Word document. I love using different fonts, so I wanted you to have a nice copy with the "cool" fonts. Here is a link to the punch cards. I copied the cards on cardstock through our copy machine.

I'm really looking forward to seeing how this works out the rest of the semester!

Homework Pass (10)

Re-Do Lab Pass* (15)

*Must have a C or better on test to use.

### Geometry Project

This year in my Advanced Geometry class, we did a project on solids. The students had to create a 3D figure using at least one of each of the solids we discussed in class (Sphere, Cone, Cylinder, Prism, Pyramid). The projects were to be completed at home. On the due date, the students brought their projects to class and found the surface area and volume of their figure. Here are the projects. I thought the students did a fantastic job and I think I will continue to do this project! Very proud of the kids! (I told them they could add things like animals and the tractor for fun.) Here is the handout I gave to the kids. A BIG THANK YOU to my friend Erin for the project!

This one lights up!

This one moves up and down!

This one is almost entirely edible!

### Math Dictionary

Wow, it's been FOREVER since I've posted anything on here! I hope to start posting more regularly, so please continue to come back!

I really like these notecards. Students can quickly find the information they are looking for in the math dictionary along with figures, examples, and sometimes more importantly, non-examples.

**Math Dictionaries**I do in my Geometry class. As some of you know, Geometry is full of a TON of**new definitions**for the students. Coplanar, supplementary, similar, tangent, the list goes on. Geometry is also jam packed with**theorems and postulates**. Since we don't use our textbooks very often, I have my students make a Math Dictionary of all the terms, postulates, and theorems we discuss in class.Here's what we do:

The

**Math Dictionary**is made using**notecards and a notebook ring**. At the beginning (or end) of a lesson, the students are shown the terms for the lesson as well as any theorems or postulates we will be discussing. The**students write the term on the front**of the notecard. The**definition**of the term**and any figures**pertaining to the term are also**drawn on the back**. Often,**examples**of the term**and non-examples**are**drawn on the back**of the card. For theorems and postulates, the students write the name of the theorem or postulate on the front and then write the theorem/postulate on the back in words and in symbols. We also discuss what it means in "non-Math terms" and that is written on the back of the notecard as well. The students are to then but the notecards in alphabetical order so that the notecards can be easily found (the reason for the notebook ring).I really like these notecards. Students can quickly find the information they are looking for in the math dictionary along with figures, examples, and sometimes more importantly, non-examples.

**Math Dictionary**. The quality of the picture isn't clear, but you get the idea of how they look. I do checks on the notecards to make sure the students are completing the cards.## Thursday, September 23, 2010
