The Lesson
In my eighth grade math class, I taught a review lesson on adding and subtracting integers. This lesson was taught in order to ensure proficiency before moving into solving equations. It was my intention to incorporate many pieces of technology to create a successful learning environment for my students. In order to reach the learning style of all my students, I implemented a variety of teaching strategies: small group discussions, large group instruction, technology, and partner work.
Multiple learning theories are evident in this lesson plan. Combining both behaviorism and constructivism, students learn through guided practice and collaboration with peers. Through guided practice, students are active listeners and absorb information through lecture. With allowing students to collaborate together, knowledge is being built on what students contribute to peer interactions and conversations.
Implementation of the Lesson
The objectives of this lesson were the following: 1) Applying and extending previous knowledge of addition and subtraction. 2) Use number lines to represent addition and subtraction of integers. I planned this lesson with the knowledge that my students really struggled with this concept in seventh grade. Knowing this information allowed me to think of new and creative ways to implement instruction that would help students retain the concepts being presented.
The lesson started with a quick review of how to add and subtract integers. A major change that I would make to this lesson is having students fill out a graphic organizer to help arrange their knowledge. After our review, students worked independently on six problems before being paired up with a peer to compare and discuss answers. From there, students were assigned a six-question assessment that covered rules for adding and subtracting integers as well as practice problems. We then used the Plickers application to gather the assessment data. Never having used this application before, we had minor user error. As the teacher, I learned that in order to scan the students’ cards I had to hold my cellphone camera vertically. If held horizontally, the camera scans the incorrect answer on the students’ cards. I really enjoyed seeing how students reacted when they were marked wrong but were confident that they really did answer the question correctly. Advocating for their grade was evident while using this application.
Technology
Working technology for each individual student is hard to come by in my school. By researching alternatives to get students excited to learn, I found the Plickers application that can be used on the computer or on cell phone. This application allows teachers and students to have instant assessment data without the student even touching a piece of technology. Students were given an individualized card that allows them to answer multiple-choice questions by holding the correct answer on the top of the card for it to be scanned. I’ve never seen a group of students so excited to take a quiz in my three years of teaching! Students were cheering as they saw their correct answers appearing on the board!
