In Decimals, Grade 5 Workbook , we study place value with decimals and learn to perform the four basic operations with decimal numbers. We start with a short review of tenths and hundredths, after which we study numbers with three decimal digits (thousandths). Students also compare and round numbers with up to three decimal digits. The rest of the workbook is spent studying the four basic operations with decimals. We start with addition and subtraction, which the student should be familiar with from fourth grade, and then spend a considerable amount of time with multiplication and division of decimals. I have tried to emphasize mental calculations based on the conceptual understanding of decimals. For that reason, the text often includes little "tricks" that can help with mental calculations. Along with that, the workbook has lessons on long multiplication and long division with decimals. Problems accompanied by a small picture of a calculator are meant to be solved with the help of a calculator. Otherwise, a calculator should not be allowed.
