My Practice Book offers many great and helpful exercises for math in 4th grade. The focus is on numbers up to 1,000,000 and calculations involving lengths, weights, shapes, and figures. The content aligns with the curriculum and serves as a supplement to the accompanying series Learning and Understanding. The removable answer booklet quickly shows whether the tasks have been solved correctly. As an additional motivation, there are ant stickers included in the book. For each completed double page, a sticker can be placed on the coloring sheet. Once all the stickers are applied, the children will be ready for 4th grade math. The series Fit for School is recommended by teachers.
