Economics and entrepreneurship aren't the only things you can learn with lemonade. In Barbara deRubertis' early reader, LULU'S LEMONADE (Math Matters), children (between the ages of 5 and 8) learn not only about measuring liquids, but how to turn a boring day into a creatively delicious one.
As Mattie and Martin toss around ideas in an effort to cure their boredom, they decide to enter a cooking contest. But who wants to cook on such a hot day? The solution is to make lemonade. What a perfect way to spend a hot summer day. And no stove is needed!
