Typing Success in 20 Minutes a Day — Teaching Your K-12 Students to Type in 20 Minutes a Day Typing is fast becoming an important skill in our world. Making this skill available to your students is very important. Just 20 minutes of the following activities per day will give your students the finger strength and keyboard knowledge they need to be ready to include typing in their learning programs. Step 1 Knitting (编织): You can try various styles until you find the one that best suits your students’ abilities. Finger knitting is a great way to start! It helps students focus on finger strength. Knitting with needles is a little more challenging but will suit some older    students. The more practice the fingers get the stronger they will become.
