The Symmetry Drawing block creates interactive drawing activities where learners complete symmetrical patterns. One half of a design is provided, and learners draw the mirror image to complete the symmetry. Perfect for teaching reflection, line symmetry, and spatial reasoning skills.
Symmetry Drawing activities automatically mirror the learner’s drawing across the line of symmetry, helping them visualize reflection in real-time.

​
When to use Symmetry Drawing

Symmetry Drawing activities work well for:
  • Teaching line symmetry and reflection concepts
  • Developing spatial awareness and visual reasoning
  • Art and design activities exploring pattern and balance
  • Early geometry and shape recognition
  • Fine motor skill development through precise drawing

Settings

​
Canvas settings

​
Drawing height
slider
default:"12"
The number of rows in the drawing grid (1–16). Larger values create taller canvases for more detailed drawings.
​
Drawing width
slider
default:"6"
The number of columns on each side of the line of symmetry (1–8). The total width is double this value.

​
Color palette

The activity includes a customizable color palette that learners use to create their drawings. The default palette includes:
  • Red, Pink, Purple, Blue
  • Green, Yellow, Orange, Brown, Black
You can customize the colors available to learners by editing the palette in the block settings.

​
Creating a Symmetry Drawing Activity

To set up a symmetry drawing activity:
  1. Add the Symmetry Drawing block to your resource
  2. Adjust the canvas height and width to suit your design
  3. Draw the stimulus pattern on the left side of the canvas. This is what learners will mirror
  4. Optionally customize the color palette
The line of symmetry runs vertically down the centre. Learners will see your stimulus drawing and must complete the mirror image on the right side.

Tips for teachers and parents

Best practices:
  • Start with simple shapes and patterns before progressing to complex designs
  • Use fewer colors initially to reduce cognitive load for younger learners
  • Create stimulus drawings that clearly demonstrate the concept you’re teaching
  • Adjust canvas size based on complexity; smaller grids for simpler activities
  • Consider using symmetry drawing after introducing reflection concepts with physical manipulatives
  • Encourage learners to check their work by imagining folding the image along the centre line
