The geometric solid shapes, such as a sphere or cube, can be introduced to very young toddlers. Younger toddlers seem to like the solid shapes more than older preschool children. Holding beautiful wooden shapes in their hands gives a gratifying sense of feel to your curious toddlers.

We used to critique our Montessori equipment with our directress who was a developmental child psychologist. She suggested once that the solid geometric shapes were wonderful for tactile experiences and vocabulary for geometry. Her improvement for the shapes would be that they were clear and you could measure the volume of each shape.

This is something she would have liked! The lids can be removed. Measure volume using millet in a measuring cup and grade the shapes from the largest volume to the smallest volume. It's a great Montessori lesson.

It is a difficult concept for preschool children to truly understand the concrete concepts of quantities and numbers. Lesson 9 has some helpful lesson ideas for counting and early math experiences. Check it out at montessorimom.com

Today's learning and fun is brought to you by the letter p- the peanut butter letter, peanut butter you can make and peanut butter play or fun dough you can eat! Plus more activities and games for letters and words.

Montessori used the number rods for counting After counting is mastered, numbers are introduced with the 3 period lesson. Lastly, matching the numbers and matching number rod finishes the lesson.
