Unit 6

3.6C I will determine the area of rectangles with whole number side lengths in problems using multiplication.

 

3.6D I will decompose composite figures  to determine the area.

 

3.6E I will 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.

3.6B I will 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.

 

3.6A I will classify and sort two- and three-dimensional figures, including

• cones,
• cylinders,
• spheres,
• triangular prisms,
• rectangular prisms,
• cubes.

This is a fun online sorting game for quadrilaterals.

Polygon walk

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

Geometry Pictures

Today, the kiddos were asked to create their own pictures. They had to make sure to have at least one:
pentagon, hexagon, triangle, parallelogram, trapezoid


The above picture is mine.


Here's the link where I got my dot graph paper. They have a whole bunch of different sizes which is awesome.
