One Hundred Hungry Ants — Elinor J. Pinczes

This tale of ants parading toward a picnic is “one of those rare gems capable of entertaining while it instructs” (Middlesex News).
 
One hundred hungry ants march off single file to sample a picnic, but when the going gets too slow, they divide into two rows of fifty, then four rows of twenty-five . . . until they take so long that the picnic is gone!
