Letters Drill: Speed of processing
While timing yourself, pick one letter and go through each line, use a single (/) to cross out that letter. Write down your time on the top of the sheet. Have someone else score your sheet checking for missed letters and incorrectly marked letters. If you do not have a second timer, use an egg timer and set it to 3 minutes and see how many lines you can do in that time, if you can do all the lines decrease the time to 2 or 1 minutes. Repeat this drill in a day or so using the same letter, as you increase your skills change the letter you are looking for and/or look for multiple letters.
