Using graph paper to calculate perimeter can be tough.

Even though it sounds easy, many students have a hard time drawing shapes correctly and counting the units. The grid lines can make things tricky, and it's not always clear how to tell shapes apart if they aren’t drawn well.

Here are some common problems students face:

1. Common Issues:

   • Counting Mistakes: Students often miscount the units for the perimeter because lines can overlap or not be lined up right.
   • Tricky Shapes: It can be hard to understand shapes that have more than four sides, which can lead to mistakes.

2. Ways to Get Better:

   • Use Clear Lines: It's best to use darker lines and label each corner. This makes it easier to see where the corners are.
   • Different Colors: Try using different colors for each side of the shape. This makes it simpler to keep track of what part has been measured.

By using these tips, students can overcome some challenges and have a better learning experience!
