Children should know how many words by the beginning of kindergarten? 500 to 1,000 1,000 to 2,000 2,000 to 3,000 3,000 to 5,000 4,000 to 6,000

Children need to learn 2,000 to 3,000 new words each year from 3rd grade onward, about 6–8 per day. In 1st and 2nd grade, children need to learn 800+ words per year, about 2 per day. First grade children from high SES groups knew about 2 times as many words as children from lower SES groups.

i don't think so because different teachers have different materials. tehy teach differently, unless you know for sure your teacher is the exact same as others. i would just contact ur teacher
