Now that we have spent some time on patterning, students are looking at how they can find unknown information by looking for the unknown variable. For this problem, we worked together in our table groups and then created some solutions as a class.

• 640= 2x soup= 320g for Soup

• 5x= Jam 5 (130)= 650 g for Jam

• 640+ 2x= 900g= 130 g for Breadcrumbs

• 580+ 320= 900g for Peanuts
