Early Elementary Math: Angles and Fractions

This piece of equipment is called the Instrument for the Measurement of Angles and is used with the Fraction Circles to let children see how angles are measured in degrees. As your child places a whole circle here, he or she will see how one whole circle forms 360 degrees and then how smaller pieces form different degrees.

DIY tip: If you are making this at home, the measurements must be super precise! You can probably scrounge these used for fairly low prices.

Montessori House math (and more) curriculum for children in early elementary (grades one to three).

Counting in Mandarin Chinese

Here is a fun tidbit from our Mandarin Chinese project. We have a super good voice volunteer here! She is a former television broadcaster, a graduate of China's most prestigious film and media university, and now a major film producer.

The numbers here are 1 to 20 and then 30, 40, and 100.

More on our Mandarin project using Montessori for kids here.

Geometric Solid Shapes in Real Life

Using the exercise below, take the cube out. Encourage your child to handle and observe the cube.

Now ask your child to look around the house (or classroom) and find other objects that are the same shape as the cube. If you are in a Montessori classroom, this will be an easy task -- e.g. the Pink Tower is comprised of ten cubes. If you are at home, it will be interesting to see what your child finds.

Should some of the objects he or she finds not be cubes but rectangular prisms, for example, you can bring out the rectangular prism and let your child compare and contrast the shapes.

The cube also lends itself to being traced with a pencil. Your child can place the cube down on a piece of paper, trace one side, and then roll it to another side and trace that side again. As interesting patterns form, your child will see more properties of the cube.
