At the start of the day I can ask Josie what letter makes the "ah" sound,we can read a book and I can ask her to show me the lower case "a" and the upper case "A" , to show me the number 0, the number 1 , how many apples would be in a tree if there were 0 apples in the ect.. and she tells me right off. But at the end of our school day she will just guess or get it wrong. What does this mean ? Is she bored? or something else? How can I fix it ?
