KS2 students should be able to convey their thoughts through a variety of different methods such as writing, drawing or other modes of artistic creation.Therefore, assign a writing project, but allow them to select how they will present the information. For example, if you give them an assignment on the greatest landmarks in Britain, they might choose to write an argumentative essay pointing out why the landmarks highlighted are the top landmarks, a travel brochure to guide newcomers to the points of interest or a newspaper story covering the landmarks.
Allow your KS2 students to interact with some online games, whether individually or in small groups if there are not enough computers for everyone in the classroom. Websites such as Crickweb (see link in References) offer a plethora of appropriate games. For example, students can group verbs together in the "Verb Links" game, sharpen their abilities to write stories with the "Story Sequencer" and practice changing nouns from the singular to the plural form with the "Spelling Rule Tester."
Another key component of KS2 literacy is identifying errors within a text. Give students a short passage to read out loud, but make sure it contains some errors. See if the students read the errors, subconsciously correct them or ask if there is something wrong with the reading. Afterward, have the students go through that text -- or another one -- and indicate where the errors are and fix them.
The students also need to be aware of the frequency words, the appropriate vocabulary as outlined in the educational standards, in the KS2 level. Use flashcards to acquaint them with these words. As you progress through the flashcards, ask the students to use the words in a sentence. You could also write all of the target words on the blackboard. Ask students to write a story, and require them to use all or a certain number of the words that you wrote on the board.
