While we are minimizing some use of technology in school, technology is still important in our world and it is helpful in learning a second language. Playing simple videos in French helps the children learn different accents and different vocabulary that they may not be exposed to in the classroom. They also would need the visual to help them learn.

We used to play a lot of Mini TFO videos in class.   https://www.youtube.com/c/MiniTFO. Many of their songs are no longer there, which makes me sad as they were incredibly useful for learning French.  It is still a fun little program. 

Radio Canada has some French TV shows for children as well.

Another idea, which I use personally as a French second language learner as well, is watch movies that I am very familiar with. I often put on my Disney movies or Harry Potter movies in French instead of in English. We all know your child has a favourite movie that they could watch 42 times a day and they can recite the whole movie by heart, so why not put that movie on in French? They are familiar with the story, so they will understand what is happening. :)
