Type in the content of your page here. Acquisition Lesson Plan Name: **Triangles and Angles** Plan for the Concept, Topic, or Skill—Not for the Day Topic:
 * January 19-22, 2009**


 * A. Essential Question ** : **//How do I classify triangles by their angles?//**

What do students need to learn to be able to answer the Essential Question?

Assessment Prompt #1: ​ ** How do I identify angles in geometric figures? ** Assessment Prompt #2: ​ ** How do I measure angles using tools? ** Assessment Prompt #3: **How do I classify angles by identifying angles?**


 * B. Activating Strategy: Day 1: Who am I? Day 2: "Hot Seat" Day 3: Vocabulary Challenge; Day 4: "What's Already In My Head" **

Key vocabulary to preview: ​ ​**acute angle, obtuse angle, right angle, acute triangle, obtuse triangle, right triangle, scalene triangle, equilateral triangle, isoceles triangle, vertex, vertices, degrees, angle ruler and protractor.**


 * C. Graphic Organizer: Foldable for vocabulary, GO for "Whats Already In My Head", and GO for Compare and Contrast.

//D. Teaching Strategies: Whole Group, Small Groups, Flexible Grouping (Differentiation), Collaborative Pairs, Peer Tutoring, Graphic Organizers and One on One Instruction (Teacher and Student). // ** Instruction: Teaching Strategy 1: ​**Teacher will provide each student with a set of pattern blocks. Teacher will choose one of each type of shape in a set of pattern blocks. Discuss the angles found in single shapes. Students will then place two blocks together and discuss the larger angle created by both shapes. (For example, find two blocks that form a right angle). Students will discover that there are multiple solutions when finding the different type of angles.** AP#1: See Above ​ ​ **Here, you have to put what students will do to demonstrate knowledge of the assessment prompt. Students will identify angles.** Teaching Strategy 2: **Students will be given several pieces of paper cut into squares. Students will work in collaborative groups to fold the paper into the 3 different types of angles and triangles. After the students have successfully folded the angles and triangles, students will measure the angles using a protractor and record their measurements on graphic organizer provided. Students will have to measure all three sides of the triangles. Teacher would have modeled and explained that after measuring their angles, the total should be 180 degrees. Students will use the protractor the first day and the angle ruler the second day. Teacher will model how to measure angles using each tool using the smartboard or the ELMO before students begin. Teacher will facilitate to make sure students are measuring angles correctly. Teacher will use small groups or flexible grouping here as needed.** AP#2: **See Above** **Students will measure angles.** Teaching Strategy # 3: **Students will be given a stack of cards with angles and triangles on them. Students will use the graphic organizer provided to them to classify angles and triangles. Students will record in their Math journals at least one attribute that helped them identify the angle and triangle to be what it is. Activity can also be accessed on [|www.cricketweb.co.uk/assets/resources//flash/php?&file=triangles] as well (Differentiation). Some students will do it using computers while others use the graphic organizers and we will rotate after 20 minutes. Teacher(s) will be working in small groups with students who still need assistance using the protractor and angle ruler. Students will extend the same activity the next day using and identifying multiple attributes in angles and triangles instead of one.** AP# 3: ** See Above Not sure about AP#3. How should it read? **


 * E. Assignment: Homework will be assigned as needed.**


 * F. Summarizing Strategy: ​Day 1: Think-Pair-Share; Day 2: Dear Teacher Letter; Day 3: Scavenger Hunt; Day 4: I Have; Who Has or Jeopardy Game **
