My son responds super well to gamified learning. What I found is that there are plentiful options when it comes to math... but not as much so when it comes to reading.
When he was in kindergarten during the disrupted school year of 2020/21... I created a "reading version" of the classic Battle Ship game. Instead of a 10x10 grid of letters and numbers it was a 10x10 grid of K-2 "sight words" that I would randomly choose and draw onto a grid (in Excel) that could be printed.
Then we'd play by reading and repeating sight words to indicate the coordinates to attack. He loved it!
