Children can count down from 10 to one with Pop! Went Another Balloon! A Magical Counting Storybook by Keith Faulkner, illus. by Rory Tyger. A tortoise named Toby buys 10 colorful balloons for his friend Tina's birthday, but a flock of 10 pesky birds pops them one by one. Die-cut holes over the balloons gradually decrease on each page so that the number of balloons-and birds-descends accordingly. In the end, Toby delivers one red balloon-luckily Tina's favorite color.
