Dear Tanvi_16, as LR Basic user you can get an upgrade for $ 65 , which would get you the following additional items:
The Little Reader Storybook Series (25 books)
Pattern Phonics™ Flip Cards
Starter Flap Card Kit
2 Weekly Lesson Planners, one for each semester
10 sheets of Sticker Labels for playing the labeling game
Everything You Need to Know About Teaching Your Baby to Read booklet
Teaching with Little Reader booklet
2,000 BrillKids Loyalty Points
You can not buy 25 LR Storybooks separately. But as you can see from the list above, upgrading your LR to deluxe would do just that for you, plus you would also get Flip cards and Flap Card kit -- super versatile tool. It saves you the trouble of printing the words on the cardboard, would you chose to do games and activities with physical flashcards. You will be able to print (or write) the words on regular paper, put it in the sleeves, and have sturdy, uniformed, customizable, reusable
flashcards for variety of flashcards activities. I found these to be truly valuable in our reading activities and games, plus it saved us a lot of money and trouble of printing the flashcards on the cardboard! Just thought to mention that.
Actually, it is also a very economical option, as it would put each book at a little over $ 2! Plus you will get a few additional materials.
