As students solve the word problems, they fill in the riddle with the corresponding letter.
My students LOVE these riddles; they are able to solve word problems and self check their answers. If they do not see their answer, then they know to try again! They love that its a riddle and not just another boring worksheet-a lot of them try and race to get the riddle answer first!!
I use for tutoring, small group, and enrichment activities.
