This is a Zip Around (I have, who has) game to be used for small group practice. It will help the students practice and learn Common Core geometry terms for third and fourth grades. Terms include, quadrilateral, parallelogram, square, rectangle, rhombus, equilateral triangle, isosceles triangle, scalene triangle, congruent, parallel, and perpendicular. I would recommend using it in groups of 6 of less. In a group of six each student has 2 cards so attentiveness will be greater. The cards on the master are in the correct order, going from broadest to less broad categories. I hope it is helpful!
