1. Place Value Columns

This activity teaches children the concept of place values in numbers, helping them understand how digits in different positions represent different values (ones, tens, hundreds, etc.).

Age Group: Suitable for children aged 7-10 years.

Materials Needed: A variety of LEGO bricks in different colors and a flat LEGO baseplate.

How to Do It:

  • Assign a color to each place value (e.g., red for ones, blue for tens, green for hundreds).
  • Ask the child to build columns on the baseplate using colored bricks to represent different numbers.
  • For example, to represent the number 243, they would stack four red bricks (ones), four blue bricks (tens), and two green bricks (hundreds).
  • This visual representation reinforces understanding of place values, making it a great preschool Lego activity.
