Fourth graders are in the midst of their geometry unit. This week we played a game called Sz’kwa, a Chinese children’s game, in one of our stations. The game resembles checkers in the way you capture opponents markers although the shape of the board is very different. The game board has 21 intersections made by curves and lines. Players take turns placing their markers on the intersections trying to surround their opponent thereby capturing their opponent’s marker(s). While students played Sz’kwa, the other station worked together to use their knowledge of quadrilateral “clubs” to sort and group quadrilaterals. Fourth graders know that squares are an exclusive club where you must have four equal sides and four equal angles to get in; however they can also join other clubs like the parallelogram and rectangle clubs. Students had to choose if a rhombus is always, sometimes, or never a rectangle; or if a trapezoid is always, sometimes, or never a parallelogram.
