Books for a 6 year old

What is your nephew interested in?

When my daughter was in first grade, the teacher
insisted that they read easy children books of the likes
of Dr. Seuss.

She thought it was necessary for them to enjoy reading
and not get into advanced books too soon. If they understand the stories and have little difficulties in reading
than they're more apt to contintue reading.

Well, it worked for us - my daughter is now 9 years old
and loves to read (mostly chapter books like Amelia Bodelia
and Junie B. Jones)

My daughter is 6 and in kindergarten. What I look for is books with lots of 3 letter words as that is what she is learning to read now. Typically I sit down and read the longer words and have her read the three letter words. Do you get an opportunity to spend time with your nephew? If you so, you could read one of the books you get for him. And like Noddy suggests, the best books are those that is subject material interesting to your nephew. You should be able to find the appropriate subject matter in any reading level. You could also go to a book store that has an extensive children's section and ask for suggestions on what books are popular for his age group.

My son has been reading those magic treehouse books. He seems to like them very much.

Maybe the "Henry and Mudge" series by Cynthia Rylant?

Revolting Rhymes by Roald Dahl? a retelling (very funny) of the well known nursery stories in rhyme - but with a twist - brought up to date and looked at clearly - Goldilocks is a little vandal who gets her comeuppance for breaking and entering, scoffing the food, breaking the chair and bed ..... It should appeal to his sense of humour and rhythm and rhyme enhance reading skills.

I'd ask the first grade teacher what reading level the little guy is on. Then I'd take him to the bookstore and let him pick out a few that are on his level. They're always more interested when they choose the book themselves.

I just loved reading Dr. Seuss to my niece, and now I just love reading Dr. Seuss to my daughter.

His elementary books like One Fish Two Fish Red Fish Blue Fish are excellent as beginning reader books.

Dr Suess for sure! Kids like it when you make an arse of yourself trying to get through Fox in Socks. But, I bet they could read it just fine since they concentrate on each word at a time.

I agree that you should shop for him WITH him.

Also if you just can't get him to avoid the video games they do have reading and math video games. Will he play them is another thing. You might try books with cars or big trucks, things that capture his attention. My mom had a hard time getting my brother to read and his teacher got him into comic books. that got him interested in reading because then they would tell him if you read one book then you get one commic of your choice and it became a collection for him.
Anyhow good luck.
