These letter exercises will help increase your concentration and mental endurance. The better you become at focusing your attention on the task, the faster you will get at each exercise.
1. Recite the alphabet backwards.
2. Recite the alphabet skipping every other letter. (A, C, E, G, …)
3. Try spelling two words by alternating one letter at a time (example with words “carrot” and “potato”: cpaortraotto)
4. Pick a word and spell it. Then shift it by a letter and spell again. Repeat. (example: RELAX, ELAXR, LAXRE, AXREL, …)
Remember, this is a mental exercise, so try to do it with your eyes closed.
