Reflection: Rigor How to Create a Fraction Strip Poster: A Performance Assessment of Vocabulary - Section 2: Active Engagement

This task was designed to give the students more opportunity to use the vocabulary introduced to them already in a real world context.  Giving children technology (i.e.: ShowMe, poster material, tape recorders, or time in front of the room with the board) is an excellent way to draw them into experiences that naturally require the use of vocabulary.

The students in my class used many vocabulary terms related to fractions when describing their poster in a "training video" setting.  In the videos shared in the Active Engagement Section, you hear the girls use at least 9 terms: fractions, whole, equal parts, half, fourths, 4 eighths, thirds, sixths, and making comparisons.  In order to make comparisons, students have to use analytical thinking. Comparisons are one of the ways to up the rigor in your classroom.

If you use this lesson, I recommend that you not be too focused on the "production values". These training films are authentic pieces of student work. Your focus is on use of vocabulary, and creation of a concrete representation, to show, describe, and compare fractions.
