______I know how inches, feet, and yards relate to each other.

 

______I know how centimeters and meters relate to each other.

 

______ I can use standard US and metric units to measure length.

 

______ I can estimate lengths based on common units (centimeter, inch, foot, yard, meter).

 

______ I can determine when estimates or exact measurements are needed.

 

______ I can find perimeter using standard units.

 

______ I can recognize and explain possible sources of measurement error.

 

______ I can compare different paths that have the same length.

 

______ I know what a polygon is and can identify one.

 

______ I can classify polygons by attribute, including number of sides, length of sides, and size of angles.

 

______ I can combine polygons to make new polygons.

 

______ I can recognize the number of sides as a descriptor of various polygons.

 

______ I can describe attributes and properties of quadrilaterals.

 

______ I can tell how squares and rectangles are related.

 

______ I can identify a right angle (a 90° angle)

 

______ I can measure acute angles by relating them to 90 degree angles.

 

______ I can use known angles to find the measure of other angles.

 

______ I can find the area of symmetrical designs.

 

______ I understand that the larger the unit of area, the smaller the number of units needed to measure the area.

 

_____ I can visually divide irregular polygons into two shapes that have equal area.

 

______ I can find the areas of polygons by decomposing the shape.

 

______ I can find the area of polygons using square units.

 

______ I can find the area of rectangles.

 

______ I can find the area of a triangle in relation to the area of a rectangle.
