This product is for a build-a-farm activity with system of equations word problems. There are 2 versions of the activity one with just elimination type word problems and one with mixed elimination and substitution problems. In either version the goal is the same which is to figure out how many of each animal they are supposed to have on their farm. Solving the word problems will help the students figure that information out. There is a Google Drawing integrated aspect to the activity where the students drag and drop the correct amount of animals in their correct spot on the farm. There are 10 of each type of animal, but students are only supposed to drag the number of animals that they found when solving the word problems. The link to the activity is in this product. There is also a paper version for the farm activity if the online version is not desired.
