Please try this FREE set as an introduction to my wide variety of printable Multi-Match game cards. With these cards, students match triangles shown on grids to the area, to calculation cards, or to another triangle with the same area (CCSS 6.G.1). This set is also available as part of a Grade 6 Games Bundle recently featured in th TpT newsletter. ~by Angie Seltzer
