Materials Needed:

-Wooden blocks or foam blocks (various sizes)
-Cardboard tubes (paper towel or toilet paper rolls)
-Flat cardboard pieces or wooden planks
-Foam pool noodles (cut in half lengthwise)
-Small cars or balls for testing ramps
-Tape or non-slip shelf liner (to keep ramps stable)
-Clipboards, paper, and crayons (optional for drawing designs)

Step-by-Step Directions:

-Designate a space in the classroom or outdoors with blocks and open floor space. Lay out all ramp-building materials so children can easily see and choose what they want.

-Tell children they get to create ramps using blocks and the materials provided. Demonstrate a simple ramp using a flat piece of cardboard and a block base.

-Encourage children to place a small car or ball at the top of their ramp and see what happens. Ask guiding questions like, “What makes it go faster?” or “How can we make it more stable?”

-Invite children to change the height, angle, or surface of the ramp to see how it affects the movement. Let them try different materials or even combine them to make complex structures.

-Offer a chance for children to draw their ramp designs or explain what they built to a peer or teacher.

Assessment Suggestions:

Observation: Watch how children problem-solve, adapt their designs, and interact with peers during the building process.

Language Use: Listen for use of cause-and-effect vocabulary, comparisons, or reasoning (“It went farther because I made it higher”).

Documentation: Take photos of different ramp designs or have children describe their builds for a classroom display or learning portfolio.

Reflection Questions: After cleanup, gather the group and ask, “What worked well with your ramp?” or “What would you do differently next time?”
