In our school district, we teach 2 letters each week so that we have taught all 26 letters by the beginning of December. I am always trying different ways to help my students learn the letters and their sounds.
One way that I review letter sounds is using letter sound concentration games I created. I have my teacher assistant use these with her small group (about 6 students) while I am working with my guided reading group and two groups are doing individual activities. I print 2 copies of each on cardstock and laminate for durability. Then they play concentration with them by identifying the two pictures they have found. Some of these concentration games have been updated with color clipart.
