Teaching Numbers to 20 Task Cards

Tired of endless worksheets and complicated prep? Our Numbers to 20 Maths Task Cards are designed to make your life easier while ensuring students stay engaged and motivated. They fit perfectly in Kmart or Spotlight photo storage boxes, making organisation simple and keeping your resources at your fingertips!

These task cards support early numeracy skills and align with the Australian Curriculum Outcome:

Name, represent and order numbers including zero to at least 20, using physical and virtual materials and numerals

This key numeracy outcome builds on early number skills and prepares students for future learning in numbers to 100 and beyond. Mastering numbers to 20 is essential, as difficulties in understanding teen numbers can lead to challenges with larger numbers later on.

Common Student Difficulties with Numbers to 20

Many students face challenges when learning numbers to 20. Some common difficulties include:

  • Confusion with Teen Numbers – Numbers like 11, 12, and 13 do not follow the same pattern as the rest of the counting sequence, making them tricky for young learners to remember.
  • Number Reversals – Writing numbers like 12 and 21 incorrectly is a frequent issue as students develop number recognition skills.
  • One-to-One Correspondence – Some students struggle to match numbers to actual quantities, leading to counting errors.
  • Number Sequencing – Identifying missing numbers or counting backwards can be challenging, especially when transitioning between decades.
  • Understanding Place Value – Recognising that teen numbers consist of ten and additional ones requires explicit instruction and hands-on practice.

What Do the Numbers to 20 Maths Task Cards Cover?

Our task cards cover a variety of number concepts to help students build strong foundational maths skills, including:

  • Recognising Numbers – Identifying numbers 0-20 in digit form and translating them into number words.
  • Representing Numbers – Using number charts, grids, base-10 materials, ten frames, number lines, and place value tools.
  • Ordering Numbers – Sequencing numbers forwards and backwards, identifying missing numbers, and comparing numbers using place value.
