Montessori golden beads are golden beads, all the same size, that are used to help students understand unit quantities of tens, hundreds and thousands. A single bead comprises one unit, or a point. Ten beads strung on a wire indicates ten, or a line. One hundred is indicated by ten bars side by side, which makes a square, and one thousand is ten one hundreds stacked on top of each other, making a cube. You can use these various manifestations of these numbers to introduce the decimal system and, later, practice using it. This should be done after the child has mastered counting.
