The first batch of Spine 3: Fractions mastery professional development materials is now available to download from the Mastery Professional Development section of the NCETM website.

This first wave of publishing includes:

• (Year 3) 3.1 Preparing for fractions: the part–whole relationship
• (Year 3) 3.2 Unit fractions: identifying, representing and comparing.

Designed to support teachers in the development of their subject and pedagogical knowledge, each segment comprises a printable teacher guide and an animated presentation. Together, they demonstrate how understanding of concepts can be built through small coherent steps and the application of mathematical representations.

It is important to note that these materials are not lesson plans but they can be used in conjunction with other resources, such as high-quality mastery textbooks, to support planning.

Subsequent segments will follow throughout the summer, along with the rest of Spine 2: Multiplication and Division.

Spine 1: Number, Addition and Subtraction is already available in full.

For further information and to download segments 3.1 and 3.2, visit our mastery professional development page, where you will also find the complete list of Spine 3 segment titles.
