This "hands on" set makes a great learning center (or whole class) activity for teaching/reviewing so-mi (and la) with your students! Students (or you) select a card, read (or sing) the solfege pattern and then the group spells the pattern using clear water bottle caps. (Once school started last year the kiddos were bringing them in left and right!) The 2 line staff comes with cards for so-mi line patterns, so-mi space patterns, so-mi-la line patterns and so-mi-la space patterns. You could have 2 stations going for each concept. The 3 line staff comes with cards in so-mi-la line and so-mi-la space patterns. All cards come in color and in B&W for you.
