I can’t believe we are already at the end of the pre-writing activities for kids series here on the blog! I have enjoyed sharing some fun tips and activities for your toddlers and preschoolers for pre-writing practice! So far we have looked at horizontal & vertical lines, circle shapes, cross shapes, squares & rectangles, and diagonal lines & the “X” shape.

Let’s review the developmental sequence that children learn pre-writing shapes and lines.

  • Vertical line
  • Horizontal
  • Circle
  • Cross shape (+)
  • Right/Left Diagonal Line
  • Square
  • X shape
  • Triangle

Today we are finishing up with the diamond and triangle shapes in a fun sensory tracing activity. There is also a free printable for you to grab for this activity!

Items Needed for the Diamond & Triangle Sensory Tracing Activity:

This activity is very simple, yet gives your child some great pre-writing stroke practice!

First thing you will want to do is choose your sensory medium. I used couscous for the pictures in this post. Since my daughter is still a little young for this activity I did not have her actually complete it yet. I would not do this activity for a child under 3 years old, simply for the fact that they will probably try to place the small pieces of rice or couscous in their mouth. Also since diamond and triangle shapes are not mastered until 4 years old, this activity would not be age appropriate for under 3 years old as well.

Next you will want to print out the diamond and triangle shape printable that I included for you above! Feel free to laminate it if you wish to use it more than once to help the paper hold up well. Place it on a task tray and cover with your sensory medium.

Then have your child use their pointer finger or a paint brush (using the paint brush is a great time to practice age appropriate pencil grasp) to trace the shape. You may need to move some of the sensory medium yourself so that your child can see the start point of where to trace the lines.

After they trace the line, then have them scoop the rest of the sensory medium out of the middle while using their fingers.

The end result will look like this! After they have finished with the sensory tracing, have them pick out a crayon or pencil and trace each shape, then color each shape a color of their choice.

Also, while doing this activity you can talk about which shape is bigger and which is smaller. There is a small and large version of each shape on the printable. Lots of great skills being practiced here in a fun way!
