We like the 70/30 rule (7 out of 3). For every 7 words the KNOW, give them 3 words they are struggling with. If they don't know 7 words yet (and that is perfectly fine) give them 2 they know and 1 they don't. Once they have mastered that word give them the 3 they know and and 1 more. Then add 2 more, etc. They need to feel confident and see progress to want to learn more.
Remember these are sight words. In order for them to be able to move to the next list they have to know the words by sight (under 3 seconds) and read them fluently in phrases (example - she said to)
We hope these tips help!
