From simple to advanced worksheets that help student identify major characteristics and classify them into groups.

Having the ability to group things and make sense of the world around us brings a sense of order to our lives and helps us find direction. In order to put things in groups the first thing you need to do is find likenesses and differences in the items that you are classifying. It is often easiest to start with the things that the items have in common. The worksheets will help prompt students to find definable characteristics that can express what the items you a grouping have in common and differ by. We will explore by to use charts to express these grouping procedures. We will also explore how this can be extended to the concept of pedigree charts and basic genetics. The worksheets include heavy use of Venn Diagrams to help students find likenesses and differences between organisms.

Why Sorting Skills Are Important for Children

By age 4, most children have an inherent ability to sort objects depending on color, shape, and size. Sorting appeals to children because it helps them bring order and make sense of their surroundings. While it's a fun activity, it improves a child's cognitive abilities.

Sorting skills are important for children because they help them focus on details, think critically, and develop problem-solving skills. The ability to notice similarities and differences promotes reasoning and makes a child good in numbers and daily choices.

When you first identify these characteristics the differences between them will often present themselves more vividly. We find that students quickly get the hang of this through experience. We would encourage students to review this skill often throughout the course of the year by simply having students perform activities like you will find below in these worksheets. A great way to do this with students is to create sorting bins and start out really general. I often start teaching it with numbers 0-9 in a pile and 10-19 in another. Then I progress to colors and shapes. Starting out simple is the best way to get this skill going in their minds.

How Do Sorting Skills Benefit Children?

Sorting is the foundation of learning numbers. Before a child can learn addition or subtraction, they need to understand what they are dealing with first.

Sorting skills benefit children by helping a child's brain process information about how items appear and relate to each other. While exploring objects, children learn to identify patterns and relationships, which make them attentive to details.

So, as kids learn to sort things, they become more observant and can develop a language to explain the attributes of something.

Grouping items according to similarities helps children apply reasoning skills and express why an object fits into a given class. Also, the process requires decision-making skills when two or more attributes are involved.

In a nutshell, sorting skills help a child to:

  • Compare items and notice similarities and differences
  • Organize and match items depending on their attributes
  • Understand relationships and make patterns

Whatever a child learns in the process will later help them in other tasks. When they encounter a situation that requires the intelligence learned, they use it to make informed judgments and decisions.

Is There Any Influence a Child's Academic Performance?

Sciences and particularly mathematics are challenging to most children. However, research shows children who learn cognitive skills before formal schooling perform well through their elementary studies.

Sorting skills can influence a child’s academic performance. From age 3, the child's brain is active, competent, and cognitive, and it is the best time to introduce sorting skills. Through comparing and grouping, children learn critical thinking, the building block of solving academic problems.

Learning to identify and sort objects gives children a positive attitude towards learning, making it easy for them to understand concepts because they already have skills to build on. As learning advances, children develop executive functions which boost their performance, including:

  • Shifting
  • Updating
  • Impulse setting
  • Goal setting

How To Introduce Sorting Skills in Children
You should make sorting fun and engaging when introducing it to a child. What you should first consider is the age of the child. For children aged 4 and 5, you can use three or four categories of sorting, and for younger ones, two.

You consider age because simple sorting activities may be less interesting for older children while too complex ones may be challenging for younger children. Then you'll need to select sorting items that children interact with daily to make the activity relatable.

Examples of items you can use in sorting are:

  • Crayons
  • Pompoms
  • Playing cards
  • Toys
  • Laundry
  • Socks
  • Marshmallows
  • Natural items such as pebbles, flowers, and leaves

To set the pace for a young child:

  1. Sort whatever item you choose in terms of shape, color, or size.
  2. Allow them to repeat the process while explaining why they group items in a particular way.
  3. Make the process habitual and advance to mathematical exercises such as making patterns and matching

Final Thoughts

Sorting is a fun activity that lays a good foundation for learning in children. As children classify objects, they develop:

  • Reasoning skills
  • Observation skills
  • Critical thinking skills
  • Problem-solving skills
  • Decision-making skills

These skills set up a child for success with numbers and other academic studies. The earlier you introduce sorting to your child, the better.
