The MormonShare website publishes a full list of free LDS talks for kids. The website of The Church of Jesus Christ of Latter-Day Saints also provides kids' lessons on its website, LDS.net.
LDS.net offers the most comprehensive resources for kids' LDS talks. Each Primary lesson includes preparatory tips for the person giving the talk, suggested materials, scripture recommendations from the Book of Mormon or the Bible and a lesson overview. The website provides suggestions for activities to accompany each talk, and offers a list of questions for discussion. Each lesson ends with ideas for enrichment activities, a closing testimony and suggestions for home scripture readings.
