Tumblebooks Library/ Advanced challenge

My first assignment was to help Alex, a 3rd grader, to find more mysteries, because he has already read most that are available in the Library.  I took time to view the Tumblebook tutorial, and found they gave so much information in it, that things weren't very clear.  I tried to narrow my search by grade level, and where I was, it came up with "no results" several times.  Frustrating!!  Then, I don't even know how I happened onto it, since the "trial opportunity" wasn't displayed on the earlier pages I had viewed. But all of the sudden I saw the "trial", so I clicked that and was able to move around and get some titles to explore.  I still didn't like the fact I couldn't narrow the search in something so simple as: grade level>boy>mysteries.  So I ended up scrolling through the "index" area of the website.  These are the titles I offered for Alex: Big Tree Gang (K-3) Beware Pirates (grade 2-5) Ghost Wolf (K-3, A/R 3.2) Ziggy's Clubhouse Mysteries & Danger at the Landings (grade 4-7, A/R 3.8)  These last two titles will be more challenging for Alex to read, but he can use the read-along feature, this would increase his vocabulary and reading ability.  And if he's been doing that much reading, he might be fine going ahead of his grade level.

Our second assignment finds us preparing for a STEM story time for school age connecting a fiction with activity, also finding some e-books.  I selected the following books: Ben the Inventor by Robin Stevenson (e-book) Ben's Robot (A/R 3.0--e-book) Flight Series 1-2-3 (math series) 10 Plants that Shook the World, Bones Never Lie, The Shuttle, Tom Swift; Young Inventor Space Hotel, Tom Swift, Young Inventor Into the Abyss (both grade 4-7), The Fossil Hunter (A/R 2.9).  There are many opportunities under the "quiz and activity" link to incorporate with these titles. This assignment took a long time, since I either couldn't find the proper search tools, or they weren't there.  So for me, it was scrolling through titles.
