Mathematics Skills and Knowledge By Grade Level

States and school districts generally follow The National Council of Teachers of Mathematics "Principles and Standards for School Mathematics" (http://standards-e.nctm.org/1.0/89ces/Table_of_Contents.html). In mathematics as in science, the standards are grouped into grades K-4, 5-8 and 9-12. With such a wide range of grades and math contend within each of the three groups, you may want to check with the teacher on their classes' specific knowledge and math skills. For example, in K-4 the standards discuss that all students should know how to multiply even though that skill is generally not taught until the 3rd grade. In high school, students following a college-bound curriculum may be exposed to more advanced math concepts which have been noted.

For grades K-4 you can expect students to know or be learning the following:

Students will have a basic understanding that math can be used to solve problems in the classroom and in their day-to-day living: like baseball statistics or counting change. They can formulate basic questions regarding math such as "How many?" or "How much?".

Students will be able to understand and use basic math symbols and communicate math problems in everyday language. At this age level they will understand that math problems can have exact answers or can be estimations.

Students will understand the basics of whole number calculations using addition, subtraction, multiplication and division, when each computational method is used and the usage of a calculator.

Students will have been introduced to geometric shapes and spatial visualization in 2 and 3 dimensions. They will have been exposed to exercises on spatial relationships such as taking a 2 dimensional pattern and determining if a 3 dimensional shape can be build from it.

Measurement, units and measuring tools are introduced to students. Students at the upper end of the grades will be familiar with the concepts of length, area, volume, as well as temperature, angle, time, weight and mass.

Students will be familiar with collecting, organizing and basic graphic representations of data.

Students will have been introduced to the concept of fractions. For the early grades, this is considered a challenging concept to communicate. For the older students, the relation between fractions and decimals is introduced.

Students have been exposed to numerical and geometric pattern recognition.
