For the lesson today we’re focusing on, our lesson essential question is about adding and subtracting fractions with like denominators. Our lesson essential question includes mixed numbers, so we needed to stop and summarize. I divided them up into teams, and half of them had adding fractions with like denominators and half of them had subtracting fractions with like denominators.

We gave each student and team a rubric that they had to follow, their guidelines were that they had to be specific. They had to use at least one form of technology, but they weren’t limited to what they could use. They could use more than one if they wanted, which many teams had selected. They could use PowerPoint, Movie Maker, Flip cameras, Audacity, I-karaoke. It all depended on what project they wanted to compile and complete to ultimately fulfill the task at hand and complete the rubric.

Objectives

  • Students will create a project of their choice to show how to add and subtract fractions with like denominators.

Procedure

  • Students will be assigned groups and topics, either adding or subtracting fractions with like denominators.
  • Students will choose a way to teach the concept to others while following a given rubric.
  • The finished projects will be presented to the class.

Technology Present

  • Computers
  • PowerPoint
  • Flip Cameras
  • Movie Maker or iMovie
  • Audacity
  • iKaraoke

Grade Level: 3-5

Note: The TIM is about teaching, not technology. The placement of a lesson on the TIM is based entirely on the teaching practices demonstrated in the lesson and not on the specific technology employed. Effective pedagogy is our concern, not whether the tech involved is the latest, greatest, or most expensive. In fact, most of the sample videos were recorded some time ago as part of the original development of the Technology Integration Matrix. As you view these videos, focus on the teaching practices. When using the TIM-O to observe a lesson, remember that you can display the detailed indicators by clicking the tab on the right if you are completing a Matrix-based observation or are reviewing the TIM profile of a question-based lesson. The TIM Tools Admin Guide contains additional suggestions for observing a lesson and developing a TIM profile.
