O-Shaped Track – Looping

The objective of this lesson is for children to explore and understand use of the O-shaped track for repeating sequences.

30-45 min.
Intermed.
Reception-Year 1

Engage

Ask the children if there’s anything they do many times a day or week (e.g., brushing their teeth, showering, cleaning their room).

Tell the children that they are going to play another game!
Model a sequence of hopping, jumping, running, walking backwards, dancing, spinning, or other actions in a circle.
Ask the children to copy what you have just done and to repeat (i.e., loop) the sequence at least twice.

Tip: For younger children and beginners, limit your loop to just one or two actions.

Explore

Ask the children to combine curved and straight track pieces to make an O-shaped train track (six curved and four straight pieces is recommended).
Using the building cards, have the children build two or three places they would like to visit on the train (see sidebar for an example).
Let’s go on a day trip!

Use some LEGO® DUPLO® figures as passengers.
Tell the children that the passengers would like to have a picnic in the forest and then visit the beautiful castle.
Can you help the passengers take the train to the forest and then to the castle?

Explain

Tell the children that the passengers enjoyed their trip so much that they would like to do it again!
Talk with the children about how they could help make this happen.

Ask questions like:

• Will you be able to help the passengers take the same trip again? How? (The O-shaped track creates loops.)
• Which action bricks will you use and why?

Elaborate

Encourage the children to build a double-ended track next to the O-shaped track.
Talk about the difference between the two types of tracks.

Ask questions like:

• What are the differences between these two types of tracks?
• Will you be able to repeat the same journey on the double-ended track? Why or why not?

Evaluate

Evaluate the children’s skills development by observing if they’re:

• Observing and describing objects and events
• Asking questions about concepts related to science and technology
• Identifying cause and effect relationships

Teacher Support

Children will:

• Understand use of the O-shaped track for repeating sequences
• Be able to compare different train track shapes and their uses

For up to six children

Each lesson has been developed using the science, science, mathematics, and technology guidelines from the National Association for the Education of Young Children (NAEYC), Head Start, and the 21st Century Early Years Learning skills.

The learning goals listed at the end of each lesson can be used to determine whether each child is developing the relevant skills. These bullet points target specific skills or pieces of information that are practiced or presented during each lesson.
