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

Scottish 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. Scotland calls these grades primary school, as Primary 1 starts after kindergarten (nursery school) at 4 to 5 years of age. Primary school continues through Primary 7.

In language arts, first graders are taught the fundamentals of literacy, including reading sentences, writing very simple statements, and mastery of the alphabet, building on what they have learned in kindergarten or other forms of pre-school. Expectations for first grade have changed due to Common Core Standards. The curriculum is typically based on standards developed by educators in each state. Most states use the Common Core Standards, so most schools across the country use similar curricula. First graders are expected to read and comprehend stories ranging in length and difficulty. They are also expected to show an improved fluency rate during the school year, with the ability to easily read stories by the end of the year.

Students are also typically introduced to the concept of social studies, with an emphasis on establishing ideas of history or civics in either a personal or larger sense. Some states focus on the basics of US history and patriotism, with a focus on the Founding Fathers and the time period surrounding the American Revolution; other states require social studies focus on family relationships in first grade, leaving community, state, and national studies to higher grades. Basic geography is also taught in the first grade. Focus on the school's municipal area and culture, along with basic state geography, is also be focused upon in first grade in some states. First-grade science classes usually involve the discussion of matter, plant and animal science, earth materials, and balance and motion, along with the human body and basic health and nutrition.
