This is a poster to help your child brush their teeth. The purpose is that the child gets to stick a white sticker in the tooth gaps when they brushes their teeth, and when the mouth is full of teeth, the child gets a reward of some kind. Preferably not candy :-D But maybe stickers or something like that. It should be fun, but not expensive.
There's a slot for each of the child's 28 teeth, a tooth-brushing every morning and evening for two weeks.
Print the face and the teeth. It's OK if the teeth is printed in black-and-white.
Cut out the face and cut open the mouth.
Let the child choose the background paper.
Glue the teeth on the paper, about 1/3 from the lower edge.
Position the face on top of the teeth, so that the teeth fill the mouth gap. Tape it on the chin with masking tape or washi tape, so that you can remove the tape later without ripping the paper. See that it's straight and as you like it.
Now, fold the head down slightly so that you don't crease the paper, put glue on the "forehead" area of the face, and press in place. YOU HAVE TO BE ABLE TO LIFT THE LOWER HALF OF THE FACE OFF THE PAPER SO THAT YOU CAN STICK THE TEETH IN THE TOOTH PIECE LATER
Decorate the face, for example with the colors of your own child, and put on the hair - in my example the hair is yarn, but it can be painted on, paper, felt or even the child's own hair. Have fun decorating.
You could make it a monster face, or an animal face, too. What ever rocks your boat.
Here's some other tips on how to make brushing teeth fun for your child :-)
