The National Council of Teachers of Mathematics (NCTM) encourages pedagogical practices that focus on understanding mathematical concepts and student explanation of their work. Interactive instructional methods that facilitate the deeper understanding of content have been correlated with higher levels of learning and achievement according multiple studies which have been documented by Marzano in Classroom Instruction that Works
Just as the number line is a useful tool for helping students compare and order whole numbers, this Interactive Whiteboard Teacher Tool uses a virtual manipulative to help students compare and order fractions from 0 to 1. In addition to understanding that fractions can be used to represent a part of a whole, it's critical for students to learn and understand that fractions are numbers with actual values that can either be ordered or considered equivalent.
Students investigate building equivalent fractions using time and money. The teacher uses questioning to assist students with making the connection between denominators and divisible units. The clock is used as a model for halves, thirds, fourths, sixths and twelfths. Money is used as a model for halves, fifths, tenths, and twentieths. Students convert the units of each model into whole numbers (minutes or cents) as well as fractions.
