Pattern Block POW...

Exploring Fractions, Decimals, Percents

Using the pattern blocks and counting the triangle as 1/12 can you make a symetrical picture, then a chart listing by color the fraction name, decimal name? Finally can you determine the % of each color you used in your picture? In your comment can you discover a connection between fractions and decimals and percents?

Your circle of % should be based upon adding up the decimals and finding parts to the total.

Mine would be:

white 5/12 = . 416

red 4/12 = .333

green 3/12 = .25

Total 12/12 = 1.00

My percents are based upon dividing 1.0 into the decima You may use a calculator to discover the results. Don't forget to multiply by 100 to change a decimal to a %

The red part is rounded to 33%

• identify, compare, and analyze attributes of two- and three-dimensional shapes and develop vocabulary to describe the attributes;

• classify two- and three-dimensional shapes according to their properties and develop definitions of classes of shapes such as triangles and pyramids;

• investigate, describe, and reason about the results of subdividing, combining, and transforming shapes;

• explore congruence and similarity;

• make and test conjectures about geometric properties and relationships and develop logical arguments to justify conclusions.
