Cut out a large heart from construction paper. Lead a discussion with pupils about comments that make them feel good and comments that hurt their feelings. Show pupils the heart and discuss how pretty and perfect it is. Ask children for examples of comments that make them feel badly. After each example, make a random fold in the heart. Stop when the heart becomes very crumpled. Explain to the children that when they hurt people's feelings, they put wrinkles in their hearts. Ask pupils for positive comments they can say to someone. After each comment, unfold one wrinkle. When the heart is completely unfolded, discuss the importance of being careful about about we say so we don't hurt anyone's heart.
Have each pupil trace one hand print onto pink or purple construction paper and cut it out. Each child then cuts out a heart from red construction paper (with your help). The hearts need to be small enough to fit inside their hand prints. You may wish to provide them with a heart template to trace. Pupils glue their hearts onto the palms of their hand prints. Help them write a simple message on their hearts such as "Be mine" or "I love you." Encourage them to give their cards to someone special.
Have each pupil cut out a large heart from white card stock. You may wish to provide them with a heart template. Provide the pupils with long pieces of pink, red or purple construction paper, cut into 1-inch wide strips. Children cut the strips into small squares and glue them onto their hearts. Instruct them to overlap their squares to create a collage. Encourage them to cover as much of the white space as possible. Let the hearts dry then hang them up for others to enjoy.
Fill a jar with candy hearts, counting how many are used. Have pupils study the jar and discuss how many candies they think are inside. Kindergarten pupils may need support to understand what a reasonable estimate is. Provide each child with a slip of paper. Children write their names and estimates on the paper, then hand them in. Take the hearts out of the jar and count them together. The pupil with the closest estimate is the winner.
