Third grade is a big step! There are more materials to cover and your child needs to assume more responsibility for their work and behavior. You can encourage him/her to do so. You may see a drop in grade average because of the increased difficulty of the work. Do not let a small drop alarm you or your child. Help your child to accept his/her ability level. Sometimes too high expectations by the parent or child can be devastating. Do a lot of praising, encouraging, and reinforcing!
