Megan pointed me to resource yesterday, and it looks very useful. Let Your Kingdom Come: Preparing Your Hearts for the King by Carri Garvey is a helpful devotional guide for your family to help you make Holy week special and build anticipation for Easter Sunday. The ideas for lent are particularly helpful--a Lenten "advent" wreath, some thoughts from Noel Piper on fasting, and a list of resources that provide other helpful and crafty ideas for teaching about Lent and Easter. Garvey offers the resource for free. So, print it off and use it however you'd like.
HT: Passionate Homemaking Yep, Megan definitely pointed me to this one. :)
