Some other things we did were:
Bible-read the story of Mary and Martha and talked about what each one was attentive to
Science/art-the kids drew a picture of the ear and label the parts
Science-did a short experiment about sound waves using water
Science-read the book The Sense of Hearing by Mari Schuh
Language-had Christian look up the word Cochlea in the dictionary
fun-played electronic games like Simon Says where they had to repeat a pattern of sounds given
I have to say that Christian is not very excited about KONOS...yet. He has an extremely hard time with change. Even if I know he will love something, he will fight me on it just because it's new and he thinks he won't like it-then he usually ends up liking it. This happened when we started Time 4 Learning last year. I knew it would be perfect for him, but it took about 3 weeks before he admitted he liked it. This year, Time 4 learning is all he wants to do for school!
Sophie, on the other hand, loves KONOS so far. She is answering most of the questions! I knew this would be the case. Last year, she would often listen in while I was teaching Christian. Sometimes I didn't even know she was listening. I would ask Christian a question and she would pipe up with the answer!
