Are your students having difficulty differentiating between the letters b and d? If you answered “Yes!” then this is the activity for you! This SMARTboard activity has numerous activities to support your students’ recognition of the two similar letters. Students have the chance to sort the letters by their appearance and sound. They also have to choose which letter correctly fits in the sentence. Repetition is the key in this interactive activity, which can be used in Kindergarten, First or Second grade. This activity was created for use in a small group remedial setting, but could also be used in a literacy center or even as whole group instruction. A follow up worksheet is included. Enjoy!
