This lesson engages students in investigating place value and the addition and subtraction of numbers by exploring computation on the number chart. Students analyse the moves of a rook chess piece and how the value of the numbers change as he moves. This builds into an exploration of how the number chart can be used as a tool to aid and model addition and subtraction using 10s and 1s. The lesson is outlined in detail including curriculum links, discussion points, extension activities and student handouts. This sequence is part of the reSolve: Maths by Inquiry program.
