My son is almost 6. He knows the alphabet and can read some words. He knows addition and substraction (with fingers) and how to count to 169. I plan to help him expand in all of those areas during the summer, but naturally (not with homework)

He likes puzzles and videogames. We made a couple Pico-8 games together. Lately he has been developing levels in Mario Maker 2. He builds legos. He enjoys going to the countryside and playing with rocks, sticks, bugs, etc. I think all those will help him appreciate math and sciences later. He has a piggy bank and he earns coins sometimes when he does good deeds. He loves counting them. I will try to do more of those during the summer, but mostly because he enjoys it.

I also intend for him to be around other children as much as he can during the summer, which he also likes. And he is missing some social practice because of the lockdown.

>> and how to count to 169

This is weird; counting is a set of repeating patterns, so getting to 99 should take him to 999. Maybe he's memorized the numbers to 169, or he's really a 12-yr-old boy who (without understanding why) likes to say "69!"?

Oh, he gets hooked up on numbers like that all the time. For a long while he thought the biggest number that existed was 54. I'll never know why.

I've got an explanation for 169 though. We're Spanish. 60 ("Sesenta") and 70 ("Setenta") are pronounced very similarly. He can handle it the first time, but when he reaches the first hundred he starts getting tired. There's a point around 169 where the 6 becomes a 7 and the 7 becomes a 6 again, and he loses track of the number he's in.

He'll get there eventually, in the meantime it is fun to watch him try :)

Maybe that's just as far as he got before he got bored.
