With short and easy to read sentences along with images that have to be either connected with the sentence or colored correspondingly, these are more than fitting for kindergarten.
And even in the same age group not every child is at the same level (some will find these difficult, some will love them and for some they will be far too easy). We created a few different versions, with different approaches as we know not all kindergartens read at the same level. More experienced kindergarten readers will love these Kindergarten Reading Comprehension Worksheets.
