Helping Preschoolers Recognizing Same Size Objects - Like many other skills, preschoolers are also taught how to recognize objects if they have similar heights. This gets rather easier for the kids, because it is not really that difficult. Children have already learnt how to categorize stuff on the basis of shared attributes. Another important fact is that children are taught what the differences in heights are. A very small but effective method use Lego blocks. They are even colored blocks which will make them easier to classify. Now take the blocks one by one and make it stand beside the original block. Eventually you will see the rise and fall in heights, which you can explain to your kids. Tell them that the bigger something is, the higher the height of the block, the more it is small, the smaller its height will be. Some of these blocks have the same height and they are known as recognizing same size objects. These worksheets help students understand how to identify objects that are very similar sizes.
