Five steps to better handwriting

    Some kids love handwriting, but others hate when it's time to put their pen to paper. Maybe they are worried about their handwriting. Are you one of them? {#blank#}1{#/blank#} Here are five steps that really work!

    Get a great grasp

    Try this — hold your pencil at the top and try to write your name. Pretty hard? But when you hold your pencil the correct way, writing is much easier. {#blank#}2{#/blank#} Hold it in place with your thumb, and your index (食指) and middle fingers.

    Let the lines be your guide

    Lined paper is your friend! Those lines can help you create letters that are the right size and proportion (均衡). {#blank#}3{#/blank#} Also be sure to fill up the lined space completely. Those capital letters should be from the bottom line to the top one.

    Slow down

    Lower the pressure (压力)

    {#blank#}4{#/blank#}That makes it harder to make the smooth lines. Try easing up and don't hold the pencil too tightly.
