We had plans to continue with a ages 6-9 Level 2, but SiSi (See it and Say it) was having SO much more success so many learners, I decided to leave it with Level 1.The ages 6-9 workbook contains everything that the ages 3-5 levels 1 & 2 have, but at a faster pace, fewer exercises per list of words, and of course higher level activities.Most families use them for ages up to 6 or 7, and then older one up t age 12.They are a GREAT supplement for those who really enjoy work pages in between the SiSi lessons, or in addition to them. Hope that helps!
