Help your preschooler say the letter and make the letter sound. Begin with the letters in their name and move on to other challenging letters. Once that activity has run its course, use the dried beans and glue them into letters, shapes, or numbers!

Parts of a Watermelon – This letter Ww activity is full of fun and wonder! Cut out an uppercase letter and color it with two shades of green – creating stripes. Talk with your child about the sound that represents the letter W. Glue the letter onto a piece of paper and color red triangles between the letter to show the red fruit. Then add black ovals to represent the seeds. You have turned your letter W into a watermelon!

Display proudly and come up with other words that have the /w/ sound. This is also a great time to talk about the life cycle of a watermelon. Check out the video below for an exciting time-lapse from seed to watermelon fruit!

Social-Emotional Activities for a Watermelon Preschool Theme

Chasing Watermelons – Go to YouTube and listen to the story, Watermelon Madness by Taghreed Najjar. This story follows a little girl who only wants to eat watermelon so she takes the whole watermelon and puts it under her bed so that she can eat it all on her own. After having a bad dream she feels embarrassed that she took the watermelon all for herself.

This story helps children learn about sharing and the importance of being flexible. Talk to your preschooler – how do you think she would have felt if she had eaten the whole melon? Why do you think it’s important to be honest? Why do you think we need to eat a variety of foods to stay healthy?

Watermelon Emotions Matching Game – Emotional development is very important in the preschool years. It’s important for preschoolers to recognize their feelings and be able to name what they feel and why. This watermelon matching game is a fun way to talk about emotions and how to manage big feelings.

Watermelon Paper Plate Art – Grab a paper plate and some green, red, and black paint. Cut the plate in half and paint the bottom green and the inside red. Use fingers or Q-tips to paint the black seeds!

Watermelon Sensory Dough – Mix together baking soda and conditioner with a little red food dye and makes for a fun sensory experience!

Watermelon Scooping – Using a melon baller or spoon, invite your preschooler to scoop out a real watermelon. Or try scooping out other melons too such as cantaloupe, and honeydew, or even try an unusual melon from your local market. Don’t forget to have a taste!

Safe Online Activities for a Watermelon Theme
