Connect the delicious dots!

Start off with a book introduction as it will help explain things in more detail in a way that your child will understand. Then, have your child pick the constellations they want to make and help them draw them out. Using marshmallows as the stars, your child will then use toothpicks to connect the dots and create a 3D version of the constellations. 

🧭 Go on an adventure! If the stars are out in the evening, try to see if you can spot the constellations that your child built that day.

📚 Books to explore: A Child's Introduction to the Night Sky by Michael Driscoll, How to Catch a Star by Oliver Jeffers, and Once Upon a Starry Night by Jacqueline Mitton 

🔢 Count your findings: Have your child count how many marshmallows and toothpicks it takes to make the constellations.

Learning Outcomes




Identifying patterns


Recognizing patterns in their environment


Step 1:

Start off by explaining what stars and constellations are.

Step 2:

On a black piece of paper, draw the constellations. Draw a dot for each star and connect them with lines that are the length of a toothpick.

Step 3:

Place marshmallows over the dots and connect them with toothpicks.

⬆️ For older preschoolers: Have the children pick their favorite constellations and draw them themselves before recreating them with marshmallows and toothpicks.

⬇️ For younger toddlers: Pick two or three constellations and help them create them. Extending their play by allowing them to play with the marshmallows on the toothpick will help promote dexitery.

🦺 Stay safe! For all children, make sure they are being careful with the toothpicks so no one gets hurt .
