Ask the class to hold up a train that is 3 cubes long, then continue having students hold up a train for each of the other cube lengths. Using their cube train as a guide have them take guesses as to how long it is. Write their guesses on the board. Check their guesses using the cube trains. Children may work in pairs to locate an object that is about the same length as the cube trains on the sheet.
Children are to trace or draw the object, then color and embellish it if they wish.
As children become familiar with larger numbers they can make cube trains to estimate and then check the length of longer objects. Children can match number cards to the cube trains to show how many cubes.
