How to arrange objects according to size?

Animal stacking blocks for
 developing seriation skills.
       Arranging objects or pictures according to size is important for cognitive development. This process is referred to as seriation skill in the early learning classroom environment. There are a number of advantages for learners who excel at this skill:
  • Students are better prepared for learning mathematics such as: the order of numbers, fractions, addition and subtraction.
  • Processes in logical thinking become developed, such as: predicting outcomes, understanding relationships between objects, and making assumptions that can be analyzed.
       Toy companies have been making products for babies for years that encourage even infants to practice seriation skill sets. I've included photos here of an animal box set that I keep among the toys in my home.
My alphabet, animal stacking blocks are stacked according to size.
These elephants with big tusks and long trunks were fun for little ones to arrange from large, to larger, to largest etc...
         Above and below are black and white prints of elephants and rhinos of varying size that I printed, cut and laminated for my classroom several years of ago and these are still in great condition. The laminated surfaces allowed me to wipe them off with a cleanser of some sort before using them over again during many different class periods. Pre-k teachers can make multiple sets of images such as these for youngsters to line up in order of size with only a bit of pocket change.
Students practiced arranging rhinos according to size in my classroom several years ago.
       Below are wild animal clip art samples that visitors may use to make their own personal sets like the projects shown above. Pull the clip art into a Word Document and shrink or enlarge the beasts in order to have prints like the ones you see in my examples. I managed to print six different sizes using standard 8 1/2 x 11 inch typing paper. Start with the largest size and then scale the images down by dragging the corners of each image down to a slightly smaller version of the same image.
