Oh, how I have procrastinated filling the early reader shelf! This is a very fluid period, not unlike your child's transition from crawling to pulling up to walking independently. Looking back, one probably came pretty quickly on the heels of the other. Finding easy readers that have longevity on your bookshelf can be a challenge.
In this phase of learning to read, children are moving beyond recognizing individual letters to combining them and learning words. Students move fairly quickly from books with one word per page to two or three sentences on a page. From there it transitions to short paragraphs and then short chapters.
Because kids will move through these books at a steady pace,quickly, variety is definitely an ally!Your local library and your child's school library have lots of excellent choices that will engage young readers.
So do you need an early reader bookshelf at home? Definitely! It is important for kids to own their own books and to have fun reading at their fingertips. If you still have them, pull out some of those toddler books that have pictures and simple words. They are established favorites, but now your daughter can read them and use them to build a word bank of sight words. Let her create picture/word cards that she can hang up or make her own book with.
You might pull out some favorite picture books, too. If you think your son has memorized the story, then ask him to point to each of the words as he reads. That will force him to look at the page and the content. You might also try reading the book from the last page to the first.
Dr. Seuss is the master of the easy reader classic, but there are other authors who ascribe to his philosophy of great books for new readers. Some of those books, like Mo Willems' Cat the Cat and Elephant and Piggy series have the "I Can Read" imprimatur on them. But some - like Duck! Rabbit! and Little Oink! by Amy Krouse Rosenthal - don't scream "easy reader" but are delightful choices for new readers, too.
When searching for books that can double as read-along stories and developmental readers, look for simple illustrations and lots of white space on a page; short sentences; and/or rhyming text.
Although easy readers are not generally literary classics, Dr. Seuss has shown us that there are are always exceptions! Just like Hop on Pop and The Cat in the Hat, there are easy readers that we keep and enthusiastically wait to share with our grandchildren.
Check your bookshelf - you may already have some favorites!
