ANGLES
Angles MA.4.G.5.1
Benchmark & clarifications from Item Specs
Ways to identify angles <G or <FGH
Student Friendly Benchmarks
Vocabulary
Research- Make folded paper with slide 18 (lesson 11.1)
Make angle from coffee stirrers- use for benchmarks of 45º, 90º, 180 &
270º- connect to acute, right, obtuse & reflex
Categorize and estimate angles in various polygons- collection of large
shapes for each table
Slide 11
Slide 12-13
Slides 14-19
Slides 20-21
Coffee stirrers
Twist ties
Construction paper shapes
Find angles and measure around classroom
30 minutes
Construct angle measure with “Hefty” paper plates
2 plates per participant•make circle the size of center piece out of construction paper & glue
on center of one plate
•find center point of each plate
•draw a line from outer edge to point (radius) & cut on this line
•slide plates together using the “cut”
•label degrees starting at 10- 36 notches = 360º
•highlight benchmark degrees 90, 180º, 270º
iTools- Geometry-Draw
Use protractor in program to help with benchmark anglesBREAK

TRANSFORMATIONS MA.4.G.5.2
Slides 24-28
Benchmark & clarifications from Item Specs
Student Friendly Benchmarks
Translations: Use pattern blocks or alphabet letters to work with
the various translations.
Slide 29
Letters made from Ellison Press
Reflections: Use mirrors and alphabet letters to explore reflections over
vertical and horizontal lines.
Transfer translations and reflections to grid paper (lessons 12.1 & 12.2)
Slide 30
Mirrors
Grid paper
Rotations: Have participants stand and move
clockwise/counterclockwise 45º, 90º, 180º, 270º, & 360º
With a paper fastener, attach a letter on the “angle” plates.
Discuss point of rotation.
Compare with use of grid paper in texts (lesson 12.3)
Slide 31
Slide 32
Spinner- Work in pairs and use letters to review all 3 transformations
iTools Geometry-Plane figures (transformations are along the bottom)
35 minutes
LUNCH
SYMMETRYdefinitions
Line Symmetry- hyperlink to video
Rotational Symmetry – define and note text lesson 12.7 (video on
desktop)
Use alphabet letters and/or playing cards decide if there is line,
rotational, or both types of symmetry
35 minutes
