First grade

First grade (called Grade 1 in some countries) is the first grade in elementary school. It is the first school year after kindergarten. Children are usually 6–7 years old in this grade level.

In England, the first year of school is called reception, and the pupils are 4 to 5 years old. However, the first compulsory school year is Year One, when children are five years old. As most primary schools have a reception class which is treated like a compulsory school year, i.e. the children wear uniform and have the same school hours, most children start school in reception. The first grade is the equivalent of Year Two.

Scottish and Welsh pupils usually enter the corresponding stage one year younger. In Northern Ireland they are two years younger. In Scotland, first grade is equivalent to Primary 3. Pupils in Primary 3 are 7 to 8 years old. America call their primary education grade school where in Scotland they call it primary school as it would be primary 1 would start after Kindergarten (nursery) and you would be age 4 to 5 years of age. then it would be primary 2 the next year and so on up until primary 7 which would be your last year at primary school then you go off to high school.

In mathematics, students may learn about addition and subtraction of natural numbers, usually with only one digit, and about measurement. Basic geometry and graphing may be introduced. Clock and calendar time as well as money may also be in the curriculum.

In language, first graders are taught the fundamentals of literacy, including reading sentences, writing very simple statements and mastery of the alphabet, building on what the students have learned in kindergarten or other forms of pre-school (although because first grade is the first compulsory level of education in many U.S. states, the level of literacy in incoming students can vary widely). The expectations for first grade have changed due to the Common Core Standards. Curriculum is typically based on state standards developed by educators in each state. Most states use the Common Core Standards, so most schools across the country are using similar curricula. First graders are now expected to read and comprehend stories ranging in lengths and difficulty. They are also expected to show an improving fluency rate during the school year with ability to easily read stories by the end of the year.
