Shapes/Area Unit 6/Ch.19

CPC: November 30

Lesson One: Planes, Lesson Two: Solids Lesson Three: Area-insert for area is in your unit folder

the shapes unit is another opportunity to build geometry knowledge as well as numeracy. Ask questions as how many more..how many fewer...combined..etc.

Materials:

Pattern Blocks, Unifx Cubes, Geo Boards, GEO KITS, Solid Shapes, grid paper,tech integration (see below) IPAD Pattern App

GEOMETRY TEKS: SHAPES AND AREA

2.8 (A) create two dimensional shapes based on given attributes, including number of sides and vertices

2d Shapes /PLANES/Polygons

PLANE

A closed, two-dimensional or flat figure is called a plane shape. Different plane shapes have different attributes, such as the numbers of sides or corners. A side is a straight line that makes part of the shape, and a corner is where two sides meet.

POLYGON

Big image

Students will study the attributes of the following polygons:

triangle, square, rectangle, pentagon, hexagon, trapezoid, rhombus, parallelogram, octagon

RHOMBUS: a rhombus has four equal sides, opposite sides that are parallel, equal opposite angles and diagonals that bisect at right angles.

Big image

Parallelogram: A quadrilateral with both pairs of opposite sides parallel.

QUESTIONING IS KEY!

Name the polygons that are quadrilaterals?

Which polygon has less than five sides?

Which polygons combined have 11 sides?

How many vertices (corners) in two trapezoids? Three trapezoids?

How many sides in an octagon? Two octagons?

How many more sides does the hexagon have than the trapezoid?

CLASSIFY AND SORT

SOLIDS

2.8 (B) classify and sort three-dimensional solids, including spheres, cones, cylinders, rectangular prisms (including cubes as special rectangular prisms), and triangular prisms, based on attributes using formal geometric language

Students will learn about the attributes of: sphere, cube, rectangular prism, cones, cylinders, triangular prisms

composing and decomposing

2.8 (D/E) Compose two dimensional shapes and three dimensional solids with given properties or attributes,

Materials: Geoboards (composing plane shapes), Pattern Blocks, IPAD Patterns App

Which 3D/Solids have square faces? Which have triangular faces?

Decomposing 2D shapes

and decompose two dimensional shapes such as cutting out a square from a rectangle, dividing a shape in half, or partitioning a rectangle into identical triangles and identify the resulting geometric parts.

What shape do you get when you cut a corner of a square?

What shape do you get when you cut/partition a rectangle in half? diagonally?

2.8E According to the standard, solids are limited to prisms and do not include pyramids.

2.9 (F) Use concrete models of square units to find the area of a rectangle by covering it with no gaps or overlaps, counting to find the total number of square units, and describing the measurement using a number and the unit.

What is the area of...?

How may square units is the rectangle? square?

Sentence Stem: The area is ___square units because____.

Area-the number of square units needed to cover a surface

In your unit folder there is a hard copy of the third grade practice for area. Our students will work on the workbook practice 211-212 for this skill.

SHOW ME! Use the geoboards....

Have students show you..example...

  • quadrilateral (s)
  • a hexagon
  • a trapezoid
  • a triangle
  • a plane shape with four equal sides
  • a plane shape with four vertices
  • a plane shape with more than four vertices

Tech Integration-use the Pattern Shapes app on the iPAD to combine shapes as well as Explain Everything and Chatterpix.

Scavenger Hunt- we did this two years ago for our measurement unit, the students loved walking around the school and reporting their results back to the class. Send a group of 2-3 students at a time with a stopwatch for 10 minutes...

(F) compose two-dimensional shapes by joining two, three, or four figures to produce a target shape in more than one way if possible;


Making new shapes into other shapes… Vocabulary is important; Students will need to understand what compose and decompose mean; Have students start with composing (putting together) shapes using pattern blocks and then decompose the shapes.

Time TEKS and games

2.9 (G) read and write time to the nearest one-minute increment using analog and digital clocks and distinguish between a.m. and p.m.


Learning to tell time is challenging for children. In order to read an analog clock, they must be able to read a dial-type instrument. Furthermore, they must realize that the hour hand indicates broad, approximate time while the minute hand indicates the minutes in between each hour. As students experience clocks with only hour hands, they begin to realize that when the time is two o’clock, twofifteen, or two forty-five, the hour hand looks different- but is still considered “two”. Discussing time as “about 2 o’clock”, “a little past 2 o’clock”, and “almost 3 o’clock” helps build vocabulary to use when introducing time to the nearest minute.

Bring:

Laptops

Bring 1-2 Make & Take for a skill previously taught and/or an upcoming skill (multiplication, Measurement, etc)


I will print out your DMAC data.


Our goal is to identify the weaknesses/strengths of the students and have a plan of action to address their needs.
