Kid-friendly prayer-centered Lent

As usual, the Lenten season sneaks up on me, but I want to be intentional with my faith and hopefully help my kids develop their own faith in the process.  During the Advent season we prepare our hearts for the birth of Jesus.  And during the season of Lent, I want us to prepare our hearts and acknowledge the gift of salvation that was accomplished on Easter.  People of different faiths have different observances for Lent.  Some will fast from foods as a form of self-denial and/or practice of self-control.  Others will spend more time in prayer and performing acts of service.  Whatever you choose to do, may it be God honoring.  And here is what I've chosen to do this year with my kids and I've listed other ideas I've tried in the past.

Sacrifice Beads - 2019
I'm so excited about this idea.  I get to involve my children in a craft that is easy to do.  Bonus since I already have the supplies in my houses.  And I'm encouraging them to pray daily and throughout the day too.  Instructions can be found with the link above.  Two ways we'll be using this:
1.  Slide a bead down every time you pray for someone or complete an act of kindness.  I've even added letter beads so we can pray for each person in the family
2.  Slide the bead down as you recite a memory verse (ex. a bead for each line of the "The Lord's Prayer" or for each word of a memory verse)
