Let's Think Maths

Let’s Think Maths (or CAME – Cognitive Acceleration in Maths Education) supports the development of mathematical reasoning and problem solving from Early Years to Key Stage 3. The Let’s Think lessons complement a mastery approach to teaching and learning. Ofsted have recommended Let’s Think Maths as an approach to raising attainment and improving teaching and learning. All of the Let’s Think Maths resources have been written or approved by the same two authors and as such provide a coherent programme of lessons to support the development of mathematical reasoning from ages 6 to 14.

We strongly recommend teachers using these resources attend Let’s Think professional development in order to understand how the pedagogy relates to the lessons.  All of the impact evidence for Let’s Think / CA materials relies on teachers experiencing professional development.

Some of the following resources are exemplar lessons for you to try.  Others are packs of material now, or soon to be available via our Let’s Think Community Online. The following material is already available through the online portal:
