Draw to show the pattern blocks you used. Two pattern blocks  six pattern blocks Explanation:
Pattern Blocks are much more than simply a set of colored blocks.
They are a very powerful mathematics manipulative that may be used to support the teaching and learning of a variety of topics like,

FOR THE TEACHER • Have children find 2 of the same pattern blocks that can fit on top of the first shape shown. Then have children draw to record the shapes. Then repeat with 6 pattern blocks.
Hexagon  Explanation:
The pink Hexagon is a regular hexagon  that is,
all of the sides are the same length and all of the angles are the same size (congruent).
Likewise the blue triangle is regular, that is all of the sides are the same length and the angles are congruent, so it is referred to as an equilateral triangle.

Model and Draw

The wholes are the same size. How are the sizes of the equal parts different? There are more equal parts in the second whole.
These parts are ___________.
parts are four
Explanation:
The inverse relationship between the size of the fractional part and the number of equal parts in the whole when given the same size whole differs.
The greater the number of parts, the smaller the size of the parts and
the smaller the number of parts, the greater the size of the parts. There are fewer equal parts in the second whole.
