The lectionary for preaching is a discipline that I use.
BUT
I have always thought that children were not in the minds of the folk who put the 3 year lectionary together. We start out with Advent ( expectant waiting) and then move on to the Birth of Jesus, Epiphany and the Baptism of Jesus.
From there we hurry along to Lent and the death of Jesus on the cross.
For children, it seems very confusing - Jesus is born and then died - in a short time span.
As discussed in the Palms or Passion thread, the lectionary provides 2 alternative sets of readings for next Sunday. The passages are listed below, with links and NRSV passage headings.
