Complete the Symmetric Figures on a Grid

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Let students work through it independently, using a partner or small group only if they want to talk through their thinking, encouraging them to talk through their thinking: "What strategy are you using? How do you know that is right?" After completing the worksheet, review any missed problems together and discuss the reasoning rather than just the answer. For extra support, let students use manipulatives or draw pictures alongside the written problems. These symmetrical shapes worksheets work well as daily practice, homework, or a focused review activity.

Draw the missing half of 4 figures on a square grid so they match across a dashed line. A line of symmetry is a line that folds a figure into two halves that match exactly. The directions on the page read: Look at the half of each figure that is drawn. Then, use the grid to draw the other half so the two halves match across the dashed line. An answer key is included.

Yes, both. We made it for 3rd Grade geometry, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with symmetrical shapes. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Activities include completing the other half of a shape, reflecting figures across a line of symmetry on a grid, and sorting shapes into symmetrical and non-symmetrical groups.

Drawing the mirror image on a grid requires students to count squares precisely and think about position relative to the line of symmetry - a strong spatial reasoning and visual thinking exercise.

Carefully drawing mirror images along a line of symmetry builds the hand-eye coordination and precision that support not just math but also handwriting and artistic tasks.

3rd graders sort shapes by their attributes and see that squares, rectangles and rhombuses are all quadrilaterals (CCSS 3.G.A.1). They find area by counting unit squares and by multiplying length and width (3.MD.C.7) and find the perimeter of rectangles and irregular shapes (3.MD.D.8). These pages also cover angles, polygons and symmetry.

A line of symmetry is a line that folds a figure into two halves that match exactly. On Draw Every Line of Symmetry, a square has 4 lines, a rectangle that is not a square has 2, a regular hexagon has 6 and a parallelogram that is not a rectangle has none. Lines of symmetry are named in CCSS 4.G.A.3, so these pages give 3rd graders an early start.

Yes. All 30 sheets have an answer key, including the area, perimeter and symmetry pages.
