A wooden menu board lists four things for sale: lemonade, cookies, muffins and popcorn. Five story problems follow, each with small pictures of what is being bought. The first two are straight addition, the third asks how much is left after spending, the fourth adds three prices, and the last asks whether two quarters and a dime are enough for two lemonades.
That last one is the best on the page. The answer is yes, exactly, with nothing to spare, and children who say no because it feels close are worth talking through. The mix of adding, taking away and deciding is what the 2nd grade standard means by word problems with money.
