Numbuko app

Numbuko is a virtual manipulative version of everyday colour maths materials for early numeracy, but with many benefits, such as blocks changing colour to let children explore number patterns.

Children join and break Numbuko blocks to make colour rods that show how numbers 1-99 work. Numbuko is a free app (no adverts/ in-app purchases) currently available on the iTunes store for iPads. 

Numbuko aims for children to freely explore independently, and learn through talk with an adult. Unlike ‘drill and practice’ apps, Numbuko lets children explore number relationships, such as addition, subtraction, fractions, odd and even, and tens and units. The app allows children to explore fundamental maths concepts for numbers 1-99, to build, save, and share creative patterns, and to construct challenges. Adding and removing colours encourages predictions, and similarly showing and hiding lines between squares prompts different methods of thinking. Including text is also an option to help in the construction of shareable resources.
