Developing early number sense is a key factor in future mathematical understanding. Building conceptual understanding with manipulatives and lots of practice counting, subitizing, decomposing quantities and numbers as well as talking about math are all building blocks to understanding. This easy-to-use resource will help you to teach all this and more!

Building Blocks Number Sense is perfect for the classroom teacher and for use as a math intervention program.

This number sense resource will help students to learn all about numbers from 0-20 and up to 100. Your students will have fun learning with the included activities and lessons to make them successful mathematicians! You will love the organizational system and step-by-step lessons and assessments.

Providing opportunities to learn through doing rather than through worksheets alone will enable students to become flexible in their mathematical thinking, setting the stage for deeper learning and critical thinking.

Building Blocks of Number Sense is a complete research-based unit that will help you to build an early learning math program for your students that models math learning on a continuum. So, while this set is for students in the pre-k-2nd grade age group, all students will have an access point because it is designed based on concepts. Once a student has mastered a concept, (not based on grade although the standards align to K-2), they are ready to move on to the next concept. This helps students learn math and move forward without leaving gaps in learning.

Differentiation is built in! Let's face it, there are many different learning abilities and styles in every class and it can be difficult to meet all of their needs. This number sense resource is suitable to use from K-2. Perfect if you change grades or have a wide range of abilities in your classroom.

This complete resource contains:

  • an organization system for you to use a binder to hold all of the information and activities if you choose
  • printables to keep track of the different stages of mathematical growth
  • observation forms
  • pre-assessment information and tools
  • clear descriptions of every stage of number sense development
  • matching ideas, suggestions and activities for use in plastic worksheet covers to save paper and use in math centers as well as some worksheets for practice.
  • place value games and task cards

Concepts include:


1-1 correspondence




Number Relationships

hierarchical inclusion


Addition and Subtraction

part-whole relationship

commutative and associate properties



place value

This is a great set for teachers just starting out or for teachers wanting to get a better understanding of why their early learners may be struggling. It is also a useful set for resource teachers to help identify where a child may need more learning or extra reinforcement.

Please see the preview for a closer look at what is included.

This unit is also aligned with the British Columbia Math curriculum.

to see state-specific standards (only available in the US).
Understand the relationship between numbers and quantities; connect counting to cardinality.
When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object.
Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.
Understand that each successive number name refers to a quantity that is one larger.
Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.
