Most primary students will learn about decimals in grade 4. Most students will have no significant problems when they use decimals as they behave similar as natural numbers. In grade 4 students will master the concept of decimals and will learn how to use them in addition, subtraction, multiplication and division. The biggest challenge for primary students is grasp the position or place value of a decimal number. Multiplying 100 by 0.1 or by 0.01 is a big difference of course.

Through a thorough and spiral curriculum students will master all decimal concepts from grade 4 through 6 including the conversion of fractions and percents in decimal. A good way to assess the knowledge of decimals is by using word problems that not only require decimal skills but also the skill to choose the correct methodology.
