Micro Lesson 1

Using Technology to Teach Geometry

Introduction: A hands-on, student-centered approach to facilitate the learning of quadrilaterals for 2nd Grade students that addresses Arizona State Standards (2.G.A.1): Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes. During this lesson, students will create models of six kinds of quadrilaterals: square, rectangle, parallelogram, trapezoid, rhombus, and kite. The objectives of this lesson are:

• Students will be able to identify, describe, and compare six different types of quadrilaterals. 
• Students will be able to construct quadrilaterals using Geoboard.

ISTE Standards: 

1. Facilitate and Inspire Student Learning and Creativity
2. Design and Develop Digital Age Learning Experiences and Assessments
3. Model Digital Age Work and Learning
4. Promote and model Digital Citizenship and Responsibility

Materials: 

• Promethean/SMART Board
• Quadrilaterals Song
• Student Tablets/Chromebooks/Laptops
• Geoboard Application (Available through website or on Google Chrome HERE)
• Flashcards by NKO Application- Teacher created quadrilateral flashcards

After students spend time creating each shape, students' knowledge and understanding of quadrilaterals will be formally assessed with Flashcards by NKO application. 

Instructional Preparation: In order to deliver this part of the lessons, teachers must download and sign up to use the application. Creating the flashcards themselves can be time consuming since users need to upload the pictures, which often requires searching for images and saving them to their device.  

Quadrilaterals Song (Radioactive) by Mr. Peters' Classroom

After watching the Quadrilaterals Song (Radioactive), students will learn how to create quadrilaterals on student tablets, Chromebooks, or laptops using Geoboard:

One great thing about Geoboards is that this resource can either be downloaded as an app onto devices, or be accessed via website and pulled up right in a web browser!

Formative Assessment: Teachers can informally assess students' artifacts after each shape by asking students to show their work. Teachers can take advantage by having students compare their own shapes with their classmates and self-assess or peer-assess their work.

Summative Assessment: During this lesson, a class deck of quadrilaterals was prepared to assess students' comprehension of the six different kinds of quadrilaterals by using the matching game. Once a classroom deck is created, or students create their own decks (student artifacts) and practice learned content by playing other engaging games independently, in small groups, with a partner, or compete with all of their classmates. The application permits teachers to view each individual student's progress.

Below are screenshots of student artifacts during the final assessment using Flashcards by NKO. To assess summatively whether students comprehended the content of the lesson, the created flashcards include shapes and imagery of quadrilaterals found in real life to match with the correct name or text. For English Language Learners or students with disabilities, the application provides accommodations through text-to-speech options in settings. 

As students play games with classroom decks, teachers can monitor and track each individual students' achievement for informal and formal assessment.

Conclusion: This lesson was designed for the teacher to begin with applying direct instruction and end with facilitating student learning. Direct instruction is applied in the beginning of the lesson while introducing quadrilateral shapes through the introductory video and using online geoboard. The teacher will then act as a facilitator of student learning when students apply their knowledge of the lesson through the use of the digital flashcards. After teaching this lesson to a group of adult learners and observing their engagement and interest in using both digital resources that would be integrated for second grade state standards, it is of my own personal belief that the age group for which this lesson was created would be not only engaging and fun for second graders, but would also be beneficial towards mastery of the content, thus allowing the teacher to progress on to other geometrical shapes contained with this standard.
