Crochet Montessori Geometric Amigurumi Toys

In this post, I’d like to share the free pattern for these crochet Montessori geometric Amigurumi toys.

I made these 3D geometrical shapes for my first niece who is starting to learn more about shapes and volumes.

Normally, you can find this kind of toy in wood or plastic, but I thought why not crochet them? Especially when you can make them with your favorite scrap yarn – wink, wink! – and add a little rattling ball or squeaker inside for extra sound!

This collection of patterns includes the following shapes:

• 1 – Sphere
• 2 – Half Sphere
• 3 – Cube
• 4 – Rectangular Prism
• 5 – Pentagonal Prism
• 6 – Hexagonal Prism
• 7 – Cylinder
• 8 – Cone Pyramid
• 9 – Triangular Pyramid

• Weather Sensory Cube
• Pentagon Ball
• Bear Baby Rattle

Add these patterns to your Ravelry queue HERE and favorite them (– thank you!). Or save them for later by pinning this pin to your favorite crochet board on Pinterest!

Assembly

Cut a length of yarn of approximately 45″ (114 cm).

Using the whip stitch, start by seaming together two sides of any of the two triangles. We’ll call these first two triangles T1 and T2 (photo 2 below).

Make sure that both T1 and T2, and all the triangles that you’ll sew later have the RS facing out!

Then, join the next side of T2 with one side of another triangle, which we’ll call T3 (these are the sides labeled as “b” in photo 2. The arrow in the picture shows the direction of seaming).

Paying extra attention that the RS of all triangles is facing out, sew the last free side of T2 with one side of the last triangle (T4, photo 3).

Next, seam the adjacent sides of T4 and T1 (labeled d in photo 4), and then, the last side of T4 with the adjacent side of T3 (labeled e in photo 5).

Now, you only have two last sides to sew (photos 6-7). Stuff your pyramid and add a little rattling ball inside.

Then, cut a length of yarn of about 8″ (20 cm), and sew the last two sides to close the pyramid.

Weave in all your ends.
