Sideways Arithmetic by Louis Sachar - while the math in these books is not terribly complicated, the reasoning required is twisted. While they can be fun, I would advise against them for anyone with a low level of patience/tolerance for frustration.

24 is a card based game where you use basic operations to equal the number 24. My daughter used to play online, but I think that link was broken years ago. Here are the basic rules. I suspect there are many other online versions and aps available now.

Theoni Pappas’s Penrose books introduced kids to some of the more interesting topics in math. My daughter enjoyed Fractal’s Googols, and Other Mathematical Tales.

He might also be interested in:

Programming - Scratch is a programming language specifically designed by MIT to teach kids how to code.

Secret Codes:
There is a mystery series designed for younger kids that introduces secret codes. While the plots would probably be thin for a 6th grader, he might enjoy the codes.

The Mathemagician - Arthur Benjamin

He has several videos on youtube about mental math. This is one of the longer ones. Your child might prefer one of the shorter ones depending on their interest level and patience.

My DC is in 6th grade thriving at math ,the math at school seems to be easy problem solving type. So DC seems to be bored /not challenged enough ,so planning to work on the reasoning and logical thinking sheets or any advanced sheets that would be more challenging. looking for recommendations on specific sites that you can suggest to work on during the winter break. Thanks in Advance.

One free option is to have your kid look at some AMC 8 problems. https://artofproblemsolving.com/wiki/index.php/AMC_8_Problems_and_Solutions
Another is to get an AoPS account and then do problems through alcumus https://artofproblemsolving.com/alcumus or mathcounts trainer https://artofproblemsolving.com/mathcounts_trainer

These are great but the classes are even better provided you can afford it.

Thank you so much
