Facts and suggestions
Definitions and resource descriptions are checked against the linked sources. Home activity examples are suggestions, not claims that we have measured their effects. We do not describe materials as personally tested unless we have tested them.
Numbers and results
An age range or level belongs to the resource that states it. It does not establish a child's level. Completing an activity and showing a skill without help are different observations.
Images
Learning scenes and desk images are illustrative compositions. They do not represent actual product screens or photographs supplied by customers.
Updates
When verified information changes, we review the relevant text, tables and summaries together. A date change alone is not a content update.
