In Workbook A, there are exercises covering all areas of literacy acquisition, featuring recurring and varied exercise formats that align with the reader. It serves as an integrative preparatory course for an easier entry into literacy acquisition, focusing on training precursor skills and assessing the initial learning situation.

The exercises in Workbook A focus on the letters: O o, I i, A a, M m, L l, E e, U u, S s, W w, R r, F f, N n, T t, Au au, Ei ei. There are vocabulary tasks and "Exploring with Kari and Bu pages" that provide in-depth exercises related to the reader's pages. The "I can do this" pages allow for engagement with the areas of language investigation and writing with self-assessment.

Additionally, there is digital enrichment available through QR codes that can be accessed without registration (supporting audios and letter videos). Workbooks A and B are also available as a package and include practical supplements: sound charts, writing UFOs, new: My Writing UFO with stickers, sliding UFOs, and syllable cards for syllable training. As an alternative to the workbooks, parallel and goal-oriented workbooks for support are available.
