What is maths? Children ponder this question as they use their addition skills to decode a puzzle. Students solve 46 one- and two-digit addition problems, then use the key provided to uncover a quote by mathematician Edward Kasner, possibly best known for coining the term googol, a one followed by 100 zeros. This worksheet, designed for a year three maths curriculum, is a fun way to practise addition within 20 facts, and can inspire children to think more deeply about the concept of maths.
