This URL will link you to virtual Dienes blocks. Try out the blocks.On the purple banner across the top, click on the left arrow where it says Main Base. Thenumber should get smaller. Make the number read 5.What do these blocks represent now?

Respuesta :

In this software the main base will represent the number of blocks that are in the base of the figure, so at the begining we have a block of main base 10, so we have a cube of 10 by 10

So if we reduce the main base for 5, we will have a cube of of 5 by 5.

Now the meaning of the blocks will be:

The blue one, will represend the figure in 2D so is like the surface of one of the faceses

The green one represent the figure in 1D, so it represent the hight or the lenght or the wide of the original figure

and the yellow one represent the unit, so this is the smallest figure that we can use to form any of the shapes.

When you have a main base of 5 the total number of block will be:

[tex]5\cdot5\cdot5=125[/tex]

So there are 125 blocks
