Multilink cubes
Drag a cube from the tray and drop it on a tower to clip it on top, or on an empty space to start a new tower. Grab a cube in a tower to pull it off along with the cubes above it, or grab the bottom cube to move the whole tower. To turn a tower sideways (or back up again), tap it and press Rotate, or double-tap it. Tap a colour to add it to the last tower you used. Drop cubes in the bin, or off the mat, to get rid of them.
About these online multilink cubes
Multilink cubes (also called linking or connecting cubes) are a great way to build and compare numbers. These free virtual multilink cubes work on interactive whiteboards, laptops and tablets. Pick from 12 colours, drag cubes into towers up to 10 or 20 long, turn them sideways to compare lengths, put them in order, make repeating patterns, or hide the numbers and ask the class to count.
