Bond Blocks

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

What's the system suitable for?

Comprehensively teach every addition and subtraction content descriptor from Years 1 to 3. The Bond Blocks system has two uses:

  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. Maths Intervention for Years 1 to 6
    Intervene early with young students to close the gap.
    Help students move on from counting to add and subtract..

    The Bond Block Test is used for placement and monitoring. Activities designed to support students with learning disabilities.

The Blocks

  • Bond Blocks are not scored, with individual
    unit lines. They are a representational
    manipulative that supports students to
    move from counting to calculating with
  • The length of the block helps student
    develop the concept of a mental number
  • The natural wood colour of the sustainably-sourced New Zealand Pine reduces distraction of colourful plastic and focuses children on the written 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

Every activity is completed on one A3 board by an individual student or pair.

Complete one activity a week. All you need is 8 minutes, 3 times a week. 

Every activity is:

  • modelled in a short video. Consistent school wide teaching.
  • ready-to-go with minimal equipment and setup.
  • explained with specified mathematics and language.
  • differentiated. A little easier or a little harder.

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

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 1 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.

The Maths Intervention Kit contains materials to work with 4 students simultaneously. 

Add on to your Maths Intervention kit with a one off (non-subscription) Whole School 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:

  • Maths Intervention (Years 1 – 6)
  • Mental Maths (Years 1 – 3)
  • Homework

Use the Maths Intervention activities in Years 1 to 3 as part of Mental Maths. All you need is 8 minutes, 3 times a week. Providing a robust, whole-school approach to teaching maths in the early years will reduce the number of students requiring intervention.

Send the activity boards home with students to practise and develop fluency. The website is publicly accessible so parents can view the instructional video for each activity.

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

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. 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."
Amanda H.
Intervention Teacher
"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."
