lso learn to divide the numerator by the denominator. Their knowledge of adding and subtracting fractions will be extended to adding and subtracting decimals. The multiplication algorithm for decimals will be introduced by the teacher.

Fifth grade teachers provide an in depth study of addition, subtraction, multiplication and division of fractions and decimals by building on what was learned in the previous grades. Instructional practices include using algorithms, formulas and the number line to give students a thorough understanding of fraction computation. At this point, teachers can use common errors as examples but they must be sure to present them in a positive way.

The developmental stages for acquisition of the concepts of fraction computation can vary with the individual student. The Common Core State Standards for Mathematics (CCSSM) offers guidelines for teachers as to what is developmentally appropriate for various age groups. However, these are only guidelines and each student should be assessed as an individual. The language level and ability of each child should be taken into account in order to accurately assess the child’s progress. Every teacher should understand how students acquire a concept. Most children will be able to develop fraction concepts in the fourth and fifth grades. If they understand the ideas of order and equivalence at this stage, they will be more successful later on. The job of 3rd, 4th and 5th grade teachers is to be sure they understand the concepts which is more important than understanding the procedures. It is very important that students understand concepts with whole numbers before they can understand fraction computation. In other words, children should be trained to think rather than just memorize procedures.
