So I had to figure it out how to make them notice this is a fragile tool and, at the same time, they should learn handling it correctly. Well, this is what I came with. A mouse craftivity. This is how you can make it:
1. Print the template, it doesn´t have to be big, so you can make 2 in a sheet. Clic here to download the template for FREE. For better results you can print it on cardstock.
3. Color the left button in blue and the right button in red. Here you should emphasize in the difference between left and right button. Color the back of the ears too. The body can be colored in gray.
4. Using tape, paste a little piece of thread in the back, as a tail.
5. Fold in the ears.
6. And voilá! They have a cute mouse. They should be able to look after their mouses, holding it in the correct way (one finger in each button-ear and the rest holding the body)
I hope you find this activity fun and helpfull. Please let me know how it worked for you.
