Suggested for beginners that are 7 years old or older;
 
later levels work well for intermediate level students
My other go-to series for most young beginners, I even use it for students that are up to 12 years old because of the wealth of information packed inside. This series uses a faster pace than Faber and is narrower in its approach (less stylistic diversity and less variety in theory book activities), but many have found success with the series because of its concise and direct approach. If you need a link to a specific book in the series, please contact me!
