Six round portraits down the left, six words in boxes down the right: dad, mom, grandma, sister, grandpa and brother. Start at a face and draw a line to the word that fits.
Nothing here asks for writing, which makes it the right first page for a child who is not yet forming letters but can already tell grandpa from dad. The words are printed in capitals, so it also gives a child a look at the family words in a different form from the lowercase they see on most of the other sheets. Black and white, and easy on the ink.
