Well you can’t get more straightforward than that, now can you?  The ability to sort and classify into straightforward categories comes fairly easily to many children.  You may find very young children sorting their stuffed animals into piles based on an attribute (small vs. large) or their toy vehicles into groups (cars, trains, or trucks).  This “sorting” activity can feel very fun and game like for children, so as opportunities arise, allow them to sort through materials in the classroom, the will get better and better at it so by the time they arrive in kindergarten, they’ve got this one covered.
Counting each pile is also fairly straightforward, especially since the parameters of this standard only ask that the children can count up to 10.  For most children, this is more like an “entering kindergarten” skill.  We’ve got this one covered!
