Coding Sandpit is an eight-level series full of fun-filled activities to engage young learners. The series, has been developed keeping in mind the wide scope and application of computational thinking, problem solving and critical reasoning skills in our lives in the digital era. Topics have been covered thematically, which helps in developing the computational thinking skills holistically. Computational thinking skills have been thought through the following themes: (1) Systematic Listing, Counting and Reasoning, (2) Iterative Patterns and Processes, (3) Information Processing, (4) Discrete Mathematical Modelling, (5) Following and Devising Algorithms, (6) Programming and (7) Digital Literacy.
