This week we're covering unicode in the second grade classes. Unicode is a code which most computers know that lets us type characters by using a number code. For example Ȣ is typed by holding alt down in word and typing 0546 with the number pad, then releasing alt. How many different codes can you find? Here's a hint, start with a number like 0675 (ʣ) and go up to 0676 (ʤ) and so on. Here's a chart of codes if you'd like to see how many there are.
