Be a Letter Detective! helps with letter recognition. There are 4 sheets that ask students to find a letter. The letters are r, h, n, and L. My students enjoy the idea that they are detectives.
A real magnifying glass may NOT be needed. :)
I ask my students to read the letter out loud to me and stop to circle these letters; this lets me know that they understand all of the names and not just the shapes. If you want your students to practice saying the letters but you don't feel you have enough time to have them complete this activity one-on-one or with a teacher-led group, you could have students do one of the following:
work with partners, in a small student group, work with your whole class together, complete as homework, or just say the letters to themselves. (If you are doing this as individual students, you may just want to walk around and listen to your students.)
