Geometry 3D and Translations
Jan. 31 – Mar. 4
Monday January 31
TEKS 5.7A Identify essential attributes including parallel, perpendicular, and congruent parts of two and three
dimensional geometric figures.
Focus: Attributes and Comparing prisms vs pyramids and cones vs cylinders
Materials: 3D Shapes, Faces, Edges,Vertices worksheets, 3D attribute sheets
Vocabulary: attributes, faces, edges, vertices, prisms, pyramids, cones, cylinders, parallel, perpendicular, congruent
Intro. (5 minutes)
 Put shapes on tables and have students walk around and observe and discuss differences
Whole Group – (15 minutes)
 Bring students back and draw a cube on the board labeling :
o faces, edges, and vertices
 Talk about how 3D shapes are named by the shape of their base AND either:
o cones or cylinders (round with or without a point)
o prisms or pyramids (flat surfaces or with a point)
Pair Practice (20 minutes)
 Have students walk around and write down the FACES, EDGES, and VERTICES of the shapes
Individual Practice – (20 minutes)
 Students will complete “THE QUIZ”
DOG TIME:
 What your class needs

TEKS 5.8A Sketch the results of translations, rotations, and reflections on a Quadrant I coordinate grid
Focus: Identifying transformations
Materials: Warm Up powerpoint, Transformation Intro Flip Chart, Graph Paper, and Construction paper to cut out
shapes
Vocabulary: Transformations, Translations, Rotations, Reflections
Warm Up – Featured 3D Shape ( 10 minutes)
 Use the Warm Up power point and have the 3D Shapes out so students can use if they need.
Whole Class: Intro and Activity

Transformations Intro Flip Chart
Students will cut out their own irregular polygon
Have students label points on the polygons, N, S, E, & W (like a compass rose)
Students will sketch and label the points their shape in one position (START POSITION) and in one color
o from the start position ask students to hold their shape in at one point, then rotate it, and sketch and
label points in a 2nd color – Rotation
o go back to start position ask students to flip their shape and label their points – sketch and label points –
Reflection , like a mirror
o go back to start position, ask students to slide their shape to another spot – sketch and label points Translation
Small Group / Partner (15 minutes)
 Students will work in groups of 2 or 3
o One person will call out a transformation, such as “Rotation” and the other students have to sketch that
transformation using an irregular polygon
Individual Practice
 Put up an irregular shape, like an “L” shape and ask students to show this shape as a reflection, translation, and
rotation.
o Students will need to label each rotation and explain what happened during the transformation (it
turned, it’s upside down, it’s on the opposite side…. )

TEKS 5.8B Identify the transformation that generates one figure from the other when given two congruent figures on
a Quadrant I coordinate grid
Focus: Identifying transformations
Materials: Warm Up powerpoint, Transformation Intro Flip Chart, Graph Paper, and Construction paper to cut out
shapes
Vocabulary: Transformations, Translations, Rotations, Reflections
Warm Up – Featured 3D Shape ( 10 minutes)
 Use the Warm Up power point and have the 3D Shapes out so students can use if they need.
Whole Class: Review
 Ask students to grab a marker or an object, ask them to show a:
o rotation
o translation
o reflection
 Ask students what is happening during each transformation
Small Group / Partner (15 minutes)
 Make centers cards for students to practice identifying

Have to give an explanation for each transformation
Individual Practice
 The following worksheet
