Fit for Maths 1st Grade. Learning and understanding helps schoolchildren in grade 1 to better understand and learn the school material in mathematics. The content is based on the curricula: starting with the numbers up to 20, plus and minus tasks, quantities and shapes as well as first factual tasks. Explanation boxes convey the school material, the supplementary exercises help to deepen and learn it. The removable solution booklet shows whether the exercises have been solved correctly. Did you do everything right? The removable solution booklet shows you. Each correctly solved double page is rewarded with a funny ant sticker that is stuck on the colouring sheet. Once all the tasks have been solved and all the stickers are in place, the children are fit for grade 1 mathematics. The Fit for School series is recommended by teachers.
