I love hands-on activities for making mathematics fun. I’m sharing a Montessori-inspired sticky paper shape sorting and counting activity.
My 20-month-old granddaughter, Zoey, loves this activity.

Montessori-Inspired Sticky Paper Shape Sorting and Counting
Some ideas behind this variation of Montessori geometric shapes:
Zoey LOVES the tree frog in the DK Touch and Feel Wild Animals book. It has sticky pads on its “fingers” that she feels over and over. Zoey also loves stickers, so I thought this would be a fun variation. 
DIY Montessori Geometric Shapes – tutorials that make it easy to make your own Montessori geometric shapes. Montessori Isolation of Quality – a Montessori principle I find especially important when young children are first introduced to a concept.
Materials Used in Montessori-Inspired Contact Paper Shape Sorting and Counting Activity
- Blue electrical tape or painter’s tape
- Contact paper
- Blue craft foam
- Montessori Services basket (small willow basket)
- Free printable metal inset shapes from Montessori Mom

Sorting Foam Shapes on Sticky Paper
I taped the contact paper to a window for my activity, although you could use a wall or table. I used the Montessori principle of isolation of quality by making my shapes one color. I especially like to use isolation of quality for young children in their early introductions to a concept. I only used the circle, triangle, square, and rectangle to make the activity simpler for a toddler. You could even use circle, triangle, and square only. Or, for an older child, you could use a number of the Montessori geometric shapes used in the metal insets or geometric cabinet.
First, I showed Zoey how to sort the shapes. We also counted each shape. I only cut out 5 of each shape, although you could choose the number according to the age of your child.

Later, Zoey had fun with some process art.
Basket with Foam Shapes
We keep the shapes in a basket on her shelf, which she takes to the sticky paper window whenever she wants to work with them.
