Use manipulatives, such as Skittles or Legos, to allow students to visualize objects. Then, have them divide the objects into equal groups. Students can learn about remainders when the manipulatives cannot be equally divided.
The grouping model is only one way to visualize division. Manipulatives can also be placed in one pile, and students can subtract the same number of items repeatedly until none are left or there is a remainder. They can also arrange the manipulatives into a pattern array to visualize equal size groups. Creating a 6-by-6 grid from Skittles shows 36 can be divided by 6 six times. Or, it can show it creates three groups of 12 or two groups of 18.
