Yay for a fun path to practicing addition and subtraction facts. Each correctly completed puzzle gives a route from the first number to the last number, if you do each operation along the way. The puzzles are missing one or more numbers or operation signs, so the fun is in figuring out what will fit for the missing parts. Working both backwards and forwards, students develop an increased understanding of the relationship between the operations of addition and subtraction. Originally published by Nasco as the first half of Math Map Puzzles Level A, this resource includes 50 puzzles (1 per page).
