We've started our Geometry unit!!

Students use attributes to sort, classify, and measure two- and three-dimensional figures. Students use the decomposition of rectangles into rows of squares to determine that the area can be found by multiplying.

TEKS-

3.6.A Classify and sort two- and three-dimensional solids, including cones, cylinders, spheres, triangular and rectangular prisms, and cubes, based on attributes using formal geometric language

3.6.B Use attributes to recognize rhombuses, parallelograms, trapezoids, rectangles, and squares as examples of quadrilaterals and draw examples of quadrilaterals that do not belong to any of these subcategories

3.6.C Determine the area of rectangles with whole number side lengths in problems using multiplication related to the number of rows times the number of unit squares in each row

3.6.D Decompose composite figures formed by rectangles into non-overlapping rectangles to determine the area of the original figure using the additive property of area

3.6.E Decompose two congruent two-dimensional figures into parts with equal areas and express the area of each part as a unit fraction of the whole and recognize that equal shares of identical wholes need not have the same shape
