A staircase of rods from 1 to 10 and two trains that make 10

What you can do

  • Drag rods from 1 to 10 onto the board; rods that touch end to end become a train, and the app shows its sum.
  • Label the rods with whole numbers, with fractions of a chosen whole, or with letters.
  • Switch between 2D and 3D, show or hide the grid, and draw on the board with a pen.
  • Save the view as a PNG with a white or transparent background for a worksheet or presentation.
