Bond Blocks

Building Understanding and Fluency in Addition and Subtraction with basic facts and beyond

What's the system suitable for?

Bond Blocks is a comprehensive system for the teaching of basic addition and subtraction facts. The Bond Blocks system has two purposes:

  1. Mental Maths for Years 1 to 3

    Linking part-part-whole understanding with basic addition and subtraction fact fluency and associated word problems.

  2. As a Intervention Support System for students in Years 3 – 6
    For older students who count to add and subtract.
    The Bond Block Test is used for placement and monitoring. Activities designed to support students with learning disabilities.

The Blocks

  • The blocks are not scored, reducing the tendency to simply count.
  • The natural wood colour of the sustainably-sourced New Zealand Pine reduces distraction of colourful plastic and focuses children on the numbers.
  • Ten is represented with two different blocks: Linear Ten and an Empty Ten Frame, similar to a ten strip and ten frame.
  • They are a ratio of one unit : 2 cm making them easy to manipulate.
  • They are self-checking, encouraging number sense and estimation.

There’s a lot you can do with just the Blocks themselves and the Bond Blocks Out of the Box book, but the activity boards (included in a school pack) let you do so much more.

Over 100 specific activities

The activity boards pack comes with teacher notes and at least one video lesson for each and every activity.

  • Ready-to-go and easy to use A3 boards with minimal equipment and setup
  • Specifies use of mathematical language
  • Streamlined learning and implementation so students get right to the maths

The Support:

Teaching Modelled in Video

  • Explicit teaching of the activity
  • Demonstrating to teachers how to link the mathematical manipulative, the language and symbols

Differentiations – Done!

  • Free downloads and website instructions to make the activity a little easier or harder

Buy Bond Blocks

Bond Blocks is available in several configurations

Includes one set of Bond Blocks and the Bond Blocks Out of the Box starter book.

Suitable as an introduction to Bond Blocks for parents and teachers. All activities in the book can be completed with just one set of blocks

Activities cover maths from beginning counting to addition and subtraction with two-digit numbers.

This kit can be used for Wave 2 and 3 Intervention with small groups. The activities systematically target every addition and subtraction content descriptor from the Year 1 to 3 curriculum.

Suitable for students from Year 2 to lower secondary who count to add or subtract and are not fluent with basic facts. Addition and subtraction concepts are taught explicitly. Includes missing number pre-algebra concepts and application to word problems.

Includes a colour-coded Placement Test, student goal setting and Excel whole school tracking tools. 

Every activity is modelled in a short video and has its own webpage detailing related mathematical concepts, mathematical language and differentiation.

Kit contains materials to work with 4 students simultaneously. 

Add on to your Intervention kit with a one off (non-subscription) license to print every activity board from PDFs.

This means EVERY teacher can use Bond Blocks Activities with EVERY student in the school who needs it.

Suitable for:

  • Intervention
  • Mental Maths (Years 1 – 3)
  • Homework

Schools who purchase the whole school license can send the activity boards home with their students to practise and develop fluency. The website is open to the public so parents can view the instructional video for each activity.

Pair with additional sets of blocks and materials packs. Discounts apply for bulk orders.


  • Based on research
  • With extensive classroom trials and teacher feedback

Whether you’re a teacher or homeschooling parent you can be sure Bond Blocks will be an effective tool

"The activities are prescriptive, quick and easy with few materials required. The students particularly like the partner games throughout the program and often ask “are we just playing today?” I was surprised how quickly I saw student progress. It was obvious in their speed and accuracy. The wooden blocks are the genius element of this program - so simple yet effective. The children can see, touch and manipulate the numbers and see them in relation to each other. I would highly recommend this resource for every K-6 teacher. It is applicable for intervention and core teaching."

“It’s fun. The blocks are made out of wood with numbers on. You get to build a wall, it’s tricky at first but quite fun when you complete it. I’ve learnt my number bonds of 10, 8, 5, 7, and 6. It wasn’t hard to learn because the activities are games”

Aims of the Bond Blocks System

The Bond Block System targets:

  • Fluency with number bonds, leading to recall, to add and subtract to 20.
  • Robust understanding of addition and subtraction concepts, and relationships between them.
  • Flexible, efficient calculating strategies.
  • Number concepts including place value.
  • Mathematical reasoning and problem solving.
  • All students from Years 1 to 3, and older students who require extra support.
