That is a beauty of homeschooling, not every kid learns the same way and not every kid learns at the same time. My son is a slow learner when it comes to reading and that is okay, because I know that his brain will catch up and all the worries I had and will have will be for nothing.
Okay, I kind of went off topic there.. sorry ;) So recently we did some lessons on -er and -est as comparison words. I created this fun color by words printable. All the words ending with -er are red and all the words ending with -est are blue. It is a heart picture so it will be perfect for the month of February. You can print it for free here.
