Explore the Bible
XTB (Explore the Bible) is a series of workbooks designed for children in the lower primary ages. It is originally British, but has been redone for an Australian perspective.
It's bright, colourful, fun and, yet, quite rigorous in its approach to reading the scriptures. Kids do a page a day (60 days in the book) and look at three different books of the Bible in each. My 10 year old has been doing these for about 18 months and it is the first thing he reaches for each day. I have even found that he has to rub out work in the new books because he has been working ahead.
His request for his birthday this year - his own adult Bible - the children's one just wasn't serious enough for him.
Honestly, it is the best thing we have done in Homeschooling!
