Although students first learn about decimal notation at an early age, we often observe older students who do not have an adequate knowledge of the concepts involved. Even some students who can calculate with decimals do not understand the concepts that are often involved. Understanding decimal notation is an important part of basic numeracy. This set of materials helps students with all the concepts involved in decimal notation and calculations with over 240 task cards, complete scope and sequence, and task card answers. Includes the following concepts: Introduction to Decimals Adding and Subtracting Decimals Multiplying and Dividing Decimals Percentages Exponent Rules Take a look at ourUpper Elementary Math Flow Chart to see how this work fits in with the traditional Montessori math curriculum.
