This is a 16 page file that contains two sets of 24 task cards, the answer key and a recording sheet. Each card contains one equation that is designed for students who are learning how to handle variables. Each equation can be simplified by combining like terms.
The two sets are duplicate of each other, but in one version, each equation is given using a symbol in place of the unknown. The second set is the duplicate using the same equations, but all equations are written with variables. The answer key is identical, so the cards could be used interchangeably, or used to provide differentiation for kids as they learn the system.
All equations have positive, whole number solutions.
This file is 16-page PDF that contains two sets of 24 cards. There are 12 pages of task cards (4 cards per sheet, 2 sets total), as well as 2 recording sheets and answer keys. The answer keys are identical, since the equations are simply alternate ways to depict each equation.
I use these with above level fifth graders, but have used them successfully with younger grades when combined with a system of building equations. These make a great math center.
I have used these cards either as students are developing their understanding (moving from picture to letter form for variables), or for differentiation within a group of students. Students with a better understanding of the use of variables may not require a symbol representation.
