Using the Unicorn Counting to 20 Activity in Kindergarten
Essential Kindergarten Math Skills
Building confidence with numbers and counting sets young learners up for success as they tackle new math concepts. The more familiar they become with numbers, the easier it is for them to recognize patterns and make connections.
When introducing this unicorn counting to 20 activity—whether working one-on-one, in small groups, or completing it together online—consider asking thought-provoking questions to encourage deeper understanding:
- What number do you see? Is it a one-digit or two-digit number?
- How many tens and ones are in this number?
- Does this number feel big or small? Why?
- How could you arrange your hearts to make counting easier?
By guiding students through these questions, you’re helping them think critically about numbers while making math fun and engaging!

Using Arrays to Build Numeracy Skills
Arrays are a fantastic way to help children develop early math skills in a structured and engaging way. By organizing objects in rows and columns, students can better understand number relationships, recognize quantities, and develop a sense of order when counting.
Make Numbers More Visual
Arrays provide a clear, organized way to present numbers, helping young learners easily grasp counting concepts.
Reinforce One-to-One Correspondence
A key numeracy skill is ensuring that each number corresponds to a specific object. Arrays encourage children to count in an orderly fashion, touching or pointing to each unicorn in a row to reinforce the connection between numbers and quantities.
Support Number Sense Development
Arrays allow children to break numbers into smaller, more manageable groups. For example, a 4×5 array demonstrates that 20 is made up of four groups of five, helping children see how numbers relate to one another in a structured way.
Boost Subitizing Skills
Seeing small groups of hearts arranged in an array allows students to quickly recognize patterns without needing to count each object individually. This ability, known as subitizing, strengthens number recognition and mental math skills.
Encouraging Logical Counting Strategies
Arrays help children count in an organized way, rather than jumping from one object to another at random. This structured approach makes counting easier, improves accuracy, and boosts confidence as they see their progress in a clear, predictable pattern.
