Terms of use
Use the site, print the sheets, take the guidance as general information rather than advice about your particular child.
What this site is
A free collection of generated practice worksheets and general guidance about primary education. It is provided as-is, without any warranty that it is complete, current or suited to your particular situation.
What it is not
It is not an educational assessment, a diagnosis, a curriculum, or advice from a qualified teacher, psychologist or physician about your child. The milestone pages describe general patterns across large numbers of children. They cannot tell you anything reliable about one specific child, and they are not a screening tool. If you are concerned about a child's development, speak to their teacher and, if needed, a qualified professional.
Answer keys
Answer keys are generated by the same software that generates the questions, so they are arithmetically consistent by construction. If you ever find a mismatch, please report it — that is a bug, and we want it.
Use of the material
Covered on the licensing page. Short version: print and copy freely for your own family or class, do not resell.
Liability
To the extent permitted by law, we are not liable for any loss arising from use of this site or the material on it.
