"Just found out that kids start to learn clock time in kindergarten. This game is perfect for whatever stage of time-telling a child is at because it has several difficulty levels of play - eeBoo is great at making games that stay fun as kids progress!"
"This is a super gift for almost any age, 3 on up to teenagers, and it's our new favorite gift for most elementary-age kids. Especially cool paired with a book about metamorphosis (The Very Hungry Caterpillar for young ones, something more age appropriate for older ones - just search on Amazon.)"

Whether they read on their own, or adults read them aloud, kids love the adventures 7-year-old Jack and his 6-year-old sister Annie have as they travel to new times and places in the Magic Tree House."
"(Any Groovy Girl.) Obviously for girls. When all else fails, from age 3 to 6, a doll is a great way to go. Or even before all else fails. Most little girls I know love dolls, and as a Mom I like Groovy Girls for being soft, creatively groovy, often modest and anatomically unoffensive."
