I do place a healthy amount of importance on sight words because kids need to learn and practice sight words in a balanced literacy program.
I also like to keep these sight word statistic in mind:
*12 Sight Words make up 25% of those we read and write.
*100 Sight Words make up 50% of those we read and write.
*About 300 Sight Words account for 75% of those we read and write.
We also have the pre-primer pack available!
