Integers
7th Grade Pre-Algebra
David Blake
Audience: 7th grade math students of a heterogeneous intellectual variety. These students learned about whole numbers and have been introduced to integers but have not used integers with the four functions.
Instructional Goals: The students will be able to add and subtract integers.
Timeline: This will take a few days. Here is what the students need to be through on each day
Day 1: Introduction to Integers
Adding Integers
Day 2: Subtracting Integers
Multiplying Integers
Day 3: Opposites Assessment
Student Feedback Questionnaire

Instruction:
This is a very teacher hands-off lesson the students will be self directed through the lesson. On the board write the following so the students can be directed in their understanding:
1. What is an integer?
2. How are adding and subtracting integers the same and different?
3. What rules are different with multiplying integers compared to adding?
I used this website NLVM created by a great institution. As I set up this unit on through the website I adjusted it to fit my need to teach the students through self-paced exploration. I set it up with enough time for the students to be able to have time to really explore and understand about integers. I like the website because then if I am at a workshop I can see the results of the students to ready myself for the time I come back and use it as a review not a let’s see what happened. I could see this having a few great uses. First if a student is going to gone for an extended period of time he can use this to learn. Second if I am going to be gone I don’t have to have it as a “Dead” day where the teacher can’t teach so the students don’t learn. This will be a great tool I will use in my classroom often.
