We have a few dice. Take two and roll a “target” number. Take two or three roll them to get to that target number by adding and subtracting the dice. You may have to write this out for a 6 yr old. As they get older, we add/subtract/multiply to get to the target number. Of course, you won’t get to the exact number most of the time but you can get close.
Also, playing math bingo is fun! Print out a bingo card w/ numbers and roll the dice. Again add/subtract…play bingo. We tend to use confetti that goes w/ the seasons to cover up spaces…that makes it fun too! Of course the confetti are fairly big..we have some pretty foil leafs!
A couple of games to buy are Sum Swamp…great game!! And Math Mat..this one is pricey but it can last for yrs w/ adding/ subtracting
HTH..if I think of more I will let you know 🙂
