Sorry to hear that your daughter has a hard time in kindergarten. Do you see similar behaviors at home? If so, are they new, or have they been going on for a while?
A new onset of behavioral issues may signal an endocrinological issue such as thyroid disease. Disruptive behaviors and not following directions that happen in more than one setting, may indicate attention deficiency (ADD or ADHD). In this case scenario, your daughter's regular health care provider might be able to help.
If your daughter's behaviors happen only at school, she might be bored. Talk to her and you might find out clues as to why she misbehaves. Also, ask the teachers about her conduct to get insight.
I recently read in a magazine about a research that showed children are not hyperactive after intake of sugars. The level of noise and play activities were the same for children who had ice cream and cakes and those who didn’t have sugar. In other words, children’s “hyperactivities” were not due to sugar but rather it was influenced by other children. In other words, children’s behaviors mirror each other at birthday parties, in classrooms, and other environments.
If your child is displaying disruptive behavior in class while other children are listening then there are only two reasons why she is behaving this way:
1. Your daughter is feeling challenge (the lessons are too difficult for her to understand and follow)
2. Your daughter is feeling bore (the lessons are too easy for her)
You need to find out whether your daughter is bored or challenged and then help her accordingly. If your child is being challenged, supplement the lesson she learned in school with other worksheets. I’ve included a link on kindergarten worksheets below. If your daughter feels bore, perhaps talking to the teacher and have her skip to first grade or doing half day in first grade. Good luck!
Some kids require more movement breaks than others to focus and attend in the classroom, especially at this young age. Talk to your daughter's teacher and find out how much movement vs. sitting at a desk is built into her school day. Sometimes an easy way for the teacher to figure this out is whether the child does better after recess, when they have moved around a lot. If so, then you can try getting her up a little earlier in the morning and do a little exercise: dancing to music, jumping on the bed, etc. Also the teacher can come up with little opportunities to move more during the day- passing things out in the classroom, bringing something to the office, etc.
