This is a set of 12 task cards over writing and solving one-step equations. You could have your students fill out the student answer page that I have provided which has the student write a let statement, write and solve the equation, and then answer in a complete sentence. You may also just want to focus on writing the equation and you could have students simply write the equation and not solve. All equations and answers are dealing with positive numbers. There is an answer key provided at the end of this product.
A way that you can use task cards is to print and cut then out and set them around the room. The students will walk around filling out their answer sheet. This could also be used as a station during station work.
