Duration of Activity/ Trainer 20 minutes Grade 4 Big Idea 3 Day 2 Training Process/Product (Script) Content Opening Training Materials for Activities Welcome Slides 1 Geometry Riddles Slide 2 Geometry in Our World Slides 3-10 10 minutes Benchmarks for Big Idea 3 Review of Big Idea 3 3 Benchmarks for today 40 minutes 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 Page 1 of 3 “Hefty” paper plates with notches construction paper highlighters iTools 40 minutes 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 Slide 34 Slide 35 Slide 36-38 Letters, playing cards 3-Dimensional Cube Figures MA.4.G.5.3 Benchmark & clarifications from Item Specs Student Friendly Benchmarks (specifically states figure composed of cubes-note other objects in text) Pyramids vs. Prisms –compare and contrast (lesson 13.1) Build shape and construct views on grid paper (lesson 13.4) iTools Geometry-Solid Shapes –Different views Page 2 of 3 Slide 33 Slides 39-41 Slide 42 Relational Solids Slide 43 Connecting cubes Slide 44 30 minutes Vocabulary Grab & Go Provide time for participants to prepare vocab activity and./or Grab and Go materials Page 3 of 3 Slides 45-50
