You don't need it but it is a lot more fun than TWJ. I have Jot It Down, got it when my oldest was in second grade and then even last year as a third grader she still wanted to do the projects with my kindergartener, she just wrote them herself. It has some really nice info about oral language practice, poetry tea time, movie time, museum visits ect that's quite useful for the 8 and under set. IMO the Writers Jungle is better for 9/10 and up.
