By writing down the letter names of the scales themselves, students understand how the scales are formed and why we have a circle of 5ths and 4ths. Using the sharp major scale worksheet, walk students through how to move around the circle of 5ths. Start with the C major scale. Have students count up to the 5th note of the C major scale (G) and this is how we find what the next scale will be around the circle of 5ths. They fill in the next set of boxes starting with G. To find what note will be sharped in this scale, the rule is to always add the sharp to the 7th note or degree of the scale. In the G major scale, this is F#. When the worksheet is finished, it leaves students with a handy chart to refer back to.
