I created this color sorting worksheet as a way for my students to practice decoding and reading a word, then determining of the word contains an -er or -est suffix. A great supplement to your spelling program, as well as to your language arts lessons. I plan to use this as a follow-up activity after I teach a minilesson on comparing the -er and -est suffixes. suffix. Also check out my -er and -est cut and paste sorting worksheet, available in my store. I also have a pack of 8 suffix sorts (this one included), both cut and paste and color sorts like this one, available in my store. Thanks!
