Cincuenta en la cebra / Fifty on the Zebra: Contando con los animales / Counting with the Animals (Bilingual Books)
"There is much more here than learning numbers. Each page, with a separate column of text in English and Spanish, asks the reader short questions about the picture. The format develops math and language skills and is informative and fun."  --The Young Reader, Boston Globe, Summer 1994--This text refers to an out of print or unavailable edition of this title.
