BIG HUGE PUZZLES measure 14 inches by 14 inches when complete! By creating a 4-square-by-4-square BIG puzzle, students match up various quadratic expressions with their factored form, reinforcing the following "special products":
(a + b)^2 = a^2 + 2ab + b^2
(a - b)^2 = a^2 -2ab + b^2
(a + b)(a - b) = a^2 - b^2
Works great as a pairs or group activity, as an anchor activity, or even, at this size, as an interactive bulletin board to display in the classroom (which is why I designed BIG HUGE PUZZLES in the first place - to print on card stock, laminate, and velcro the pieces to a bulletin board).
This is nice to display even before teaching students about special products to inspire a little curiosity... enjoy!
