The training booklets, revised to align with the new curriculum, provide children with additional practice material for school or home. They cover all the important arithmetic topics of the school year, reinforcing them in a lasting way. QR codes linking to explanatory videos help children better understand the learning content and offer new ways to engage with it. Self-explanatory tasks and reward stickers motivate the children, while regular "I can do this already" pages assist them in assessing their own abilities. Detachable solutions can be used for self-checking.
