6 to 10 in kanji are also easy! But they are composed of curvy lines, so practice them to write in good balances.
Six, Seven, Eight
Only 6 is a little complicated in these three letters. It seems like a broom or a dustpan. 7 is easy to remember as “a pistol hand sign on your left hand”. You can write 8 better following this way -the left line starts from middle to bottom, the right line starts from top to bottom.
Nine, Ten
9 seems funny. Check the shape well in the first image. 10 is really easy. It’s just a cross!
Extra Tips
Add one short line to cross, on 9 ! This kanji means round:)
