    How Big is a Foot?

    The King wants to give the Queen something special for her birthday. The Queen has everything, everything except a bed. The trouble is that no one in the Kingdom knows the answer to a very important question: How Big is a Bed? because beds at the time had not yet been invented. The Queen's birthday is only a few days away. How can they figure out what size the bed should be?

    Great for a math lesson on non-standard measurement and the kids loved it! If you are a teacher-- it's worth getting!


    Measuring Penny

    Leedy offers another winning math-concept book. Lisa has a homework assignment to measure something in as many ways as she can, using standard and nonstandard units. "Use your imagination!" is the last instruction the teacher gives the students. Lisa chooses her Boston terrier and the fun begins. She measures Penny and a variety of other dogs. Lisa measures how much her pet eats, how high she jumps, how much time it takes to care for her, how much money is invested in her, how fast Penny runs, and a variety of other doggie traits.

    The results are shared with readers through charts, graphs, and reports. A great introduction to measurement and a good story too.

    Counting on Frank

    This book contains wonderful illustrations of a boy and his unforgetable dog Frank. The boy, as he's referred to in the book, uses Frank as a unit of measure. The boy also calculates fascinating and interesting facts about peas (his least favorite vegetable), humpback whales, his father and the bathtub. It inspires readers to reconsider measurement and allows them to laugh at the same time.

    Me Counting Time

    A little girl approaching her seventh birthday introduces children to the elements of time from seconds to minutes, hours, days, weeks, months, and years, using concrete examples from her life to illustrate the concepts. She can write an invitation to her party in a minute and it takes one hour to make a birthday cake. Brief discussions of a Viking ship, a photo of her great-great-grandpa, and her mother's wedding dress represent more abstract concepts such as millennium, century, and decade. Colorful, childlike drawings reinforce the explanations, and the back flyleaf presents a chart reviewing the concepts.

    The Penny Pot

    At the school fair, the art teacher is painting faces for 50 cents each. Jessie would like to participate, but she just bought an ice-cream cone and has only 39 cents left. Fortunately, there is a penny pot where children put their extra change, so Jessie sits down to wait. As the youngsters approach the booth, their money is counted out and their extra pennies are added to the pot. When Jessie adds up the change and finds that there is 51 cents, she can finally get her face painted to look like a cat. The counting of money becomes a real experience in this appealing story; life-size, authentic-looking coins are used in the brightly colored illustrations, which also show multiethnic children having a good time. Money-related activities are appended. Teachers will welcome this addition to math-curriculum materials.
