These five practice pages work through a progression to develop students' understanding of equality.
I use these worksheets after introducing the idea of equality with a real pan balance. I demonstarte hoe to balance the scale using blocks, as well as what happens when the scale isn't balanced.
Each practice page gets slightly more difficult, so this is perfect to differentiate in your classroom or work through each page as a class. These pages address the second grade CCSS for Algebraic Thinking.
