Then they take out another cube and count the total number of 8 cubes. They place their cubes into a tower and identify it is composed of 5 and 3 cubes. Then students divide the tower into two equal groups of 4. They next arrange the cubes into four equal groups of 2. Finally, students learn the numeral 8.
