I use this Math Center to reinforce a variety of math skills including organizing data, greater then and less than, addition, subtraction and word problems. You can print and laminate the picture mat, graph and word problem cards. I make a copy of the addition and subtraction problems, the word problem record sheet and the greater than, less than problems for each child. They complete the graph, then use the totals for each group to create the equations and solve the word problems. I hope your students enjoy this center as much as mine do!.
