Hi paps,
Well the good news is, Little Reader and Little Math are both specially designed for the sole purpose of creating slideshow-style lessons. We've implemented many highly customizable features that are inspired predominantly by multisensory and flash card learning theory, which have been scientifically proven to be the most effective way to teach young children and babies.
As for how, I personally believe the best way to find out is to jump right in and try out the customizable features for yourself - if a specific function eludes you, we have video tutorials and help manuals available for both of our software programs, in the support section of BrillKids.com.
Cheers,
Shuki
