#### • Number: Counting, Place Value

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

Bond Blocks are a new, innovative manipulative developed by Narelle Rice and supported by Dr Paul Swan. There are a few key features of Bond 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: the 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, but the Bond Blocks are also part of a larger Bond Blocks system comprised of Games, Assessment Materials and Teacher Notes. Lessons on the Bond Blocks system are publically accessible at www.bondblocks.com

### Using Bond Blocks

Bond Blocks include two of each linear block 1 to 9, four linear 10 blocks, two blank five blocks and a marked and blank empty ten frame block.

The earliest stages of counting with Bond Blocks include counting forwards, building a set of steps from 1 to 10 where students touch the block, physically moving down the steps. Eventually the student begins to count along covered numbers and starts at points other than one.

### Typical Classroom Requirements

#### A class set:

One set of Bond Blocks between 2 or 4 students.

A class of 32 will need 8 or 16 sets of Bond Blocks

### Support and Complementary Materials

Bond Blocks has a complementary series of materials including 106 board games and assessment materials.

**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.
