Teacher year end gift

[Gingernspice]

Do you think it be fine to stick a tenner in a thank you teacher card and gift to the teacher. DD 9 prefers I buy a gift. WWYD... Gift or tenner in card?

Since dc have started school. Ive noticed on the last day of term the class teacher spends lots of time in the playground getting gifts/thinking parents for gifts. So my gift every year is no matter what i wont talk to her at the end of term apart from a smile and wave.
