all the major RE textbook publishers have websites with such resources, you can probably get the registration code from your parish DRE or catechist for free downloads
pflaum gospel weeklies is one that has a program they sell with magazines for each week, and there are free online resources as well
pflaum.com/
look at the family pages and other resources
Liguori is another, so is Celebrating the Lectionary
they all have websites with some of the material free for download or online viewing
amigos de jesus from Claretian publications is bilingual expensive for a family
all of these have subscription costs, but if your parish is already subscribing to a similar program for RE, Rcia for children, or Childrens Liturgy of the World they may be willing so simply let you have the weekly resource. I make our “leftovers” that were not used during the week available in the back of church for families, and I see people are taking them.
I subscribe to Magnifikids for all my grandchildren when they are preparing for first communion because it has the order of the Mass, Sunday readings and activities based on them for each week.
