Why Gattegno? - Play Discover Learn 24/7

# Why Gattegno?

Caleb Gattegno's methods are in essence guided discovery, but why Gattegno?

### FREE TEXTBOOKS

Gattegno's textbooks are available for free (see resource section above), and while they don't really cover time and measurement, they adequately cover everything else.   ​

### Algebra before Arithmetic

Gattegno believed in the importance of children noticing and understanding math structures before arithmetic.  When a child understands math structures, they are better able to make better predictions making them better problem solvers.

### Example

When children build trains with rods, they will notice that two rods end to end equals a rod that is longer than those two rod individually.  This is a math structure.

When given numbers, children understanding this structure will be able to predict that 1 plus 2 will give them a number larger than 1 and 2.

### Magic is in the Method

Gattegno used two tools mainly to provide discovery opportunities in math, Cuisenaire rods and the Geoboard.  ​ The magic though is in the methods and not the tools.   Today, there are many more tools by which we can apply the same methods.

### Assignment

Today, I want you to pull out the Cuisenaire rods, and begin building.  What structures do you notice?
