A toy cash register, some toy or real money and some stock for a child to set up shop with can be a fun way to practice addition and subtraction.
I also made some 'rulers' that were ten evenly spaced (marked and numbered) units long out of paper strips placed side by side into 'columns' to demonstrate the 'overflow' into the column to the left for addition to account for the full addend and the 'drawing off' from column to the left for subtraction if the current column runs out before the subtractend has been fully accounted for.
My DD found this super easy to understand and she got the idea in minutes if not seconds. But like me she gets pictures and diagrams quickly - not sure if that makes us 'visual learners' or not - I call it mechanical aptitude but I am not a psychologist.
YMMV
