Bennett, Jr. )〕 They provide visual illustrations of mathematical operations with fractions〔(Mathematical operations with fractions )〕 to gain better understanding of these operations. == Overview == Fraction Bars for halves, thirds, fourths, fifths, sixths, tenths, and twelfths form a complete deck. These bars are a part-to-whole region model for teaching the basic concepts of fractions, equality, inequality, addition, subtraction, multiplication, division, and ratios. They are plastic coated so marking bars with water-base pens can be washed off. Fraction Bars are used for teaching fractions in schools and for preparing teachers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fraction Bars」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
