Usually instruction is centered around teaching rules for using decimals
but the purpose of the illustrations in the following files is to suggest ways to provide an intuitive understanding of decimal notation
equality
inequality
and the four basic operations. These illustrations will help show teachers how to make connections between the models and the algorithms for learning about decimals.
Transparent Decimal Squares are recommended for illustrating the games and activities to a class. For further teaching suggestions and complete day-by-day lesson plans see Decimal Squares Teacher's Guide and for worksheets and tests see Decimal Squares Resource Package. . |
