This Valentine heart uppercase worksheet has 26 hearts. The ABC and XYZ are already filled in. These are the easy letters to remember the order of. The rest are harder. Kids can start by reading the ABC letters and see if the rest come to mind. You might need to provide and ABC chart to help them out and/or they can work together and help each other out. Be sure and tell them to write neatly and try to fit the letters inside the hearts. An extension activity would be to have the kids color the hearts in Valentine colors in a pattern.
