Lesson Plan The Greedy Triangle Second Grade, Common Core Learning Task Standard: 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. Student Objective Statement: I can identify the different attributes of polygons. I can identify different kinds of polygons based on their attributes. I can create various polygons using different media. I can describe in words what polygons are. Essential questions: Where do you see polygons? In what ways are polygons used? Activities & Sequencing: Hook/Engage (5 mins): Think, Pair, & Share: What is a polygon? Create an anchor chart: Using stick notes write down what you think a polygon could be and add it to the class circle map. You can change your mind later. Sequence of whole group, small group, & Independent work: 1.Set the purpose by asking questions introducing vocabulary slides 4-8 (5- 10 mins). 2. Read the story (5-10 mins). 1.Review expectations, small group/partner assignments and mathematical practices. Students break into groups to create shapes using geo-boards (10-15mins). 4.Transition Time - report back to whole group. Think, Pair, & Share: What is a polygon? Make changes to the anchor chart. Add permanent writing. (3-6 mins). 5.Whole group or with partners complete the Polygon Picture Glossary 6. Watch Shape video (5-10 mins) 7.Explore Shapes using “Foldable Glossary” (10mins). 8.Close/End of the Day review – Using performance based assessments This can be treated as an exit slip

Lesson PlanThe Greedy Triangle
Second Grade, Common Core Learning Task
Standard: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.
Student Objective Statement:I can identify the different attributes of polygons.I can identify different kinds of polygons based on their attributes.I can create various polygons using different media. I can describe in words what polygons are.
Essential questions: Where do you see polygons? In what ways are polygons used?
Activities & Sequencing:Hook/Engage (5 mins):Think, Pair, & Share: What is a polygon?Create an anchor chart: Using stick notes write down what you think a polygon could be and add it to the class circle map. You can change your mind later.
Sequence of whole group, small group, & Independent work:
1.Set the purpose by asking questions introducing vocabulary slides 4-8 (5-10 mins).
2. Read the story (5-10 mins).
1.Review expectations, small group/partner assignments and mathematical practices. Students break into groups to create shapes using geo-boards (10-15mins).
4.Transition Time - report back to whole group. Think, Pair, & Share: What is a polygon? Make changes to the anchor chart. Add permanent writing. (3-6 mins).
5.Whole group or with partners complete the Polygon Picture Glossary
6. Watch Shape video (5-10 mins)
7.Explore Shapes using “Foldable Glossary” (10mins).8.Close/End of the Day review – Using performance based assessmentsThis can be treated as an exit slip if used for formative assessment. (5-10 mins)
This story is about a Triangle who wants to be more than just a Triangle. It believes that more angles and corners will make life better. So the Triangle visits the character the Shapeshifter. The Shapeshifter changes the Triangle into many different shapes.
Do you think some shapes are better than others and why?
How will the Shapeshifter change the Triangle into different shapes?
What shapes do you think the Triangle will turn into?
Sides- Sides are the outside lines of a shape.
Angle: the space where two lines meet to make a corner.
Vocabulary
Quadrilateral
Pentagon
Hexagon
A quadrilateral has four sides and four corners. A baseball diamond is the shape of a quadrilateral.
A pentagon has five sides and five corners. Asoccer ball is made up of tiny pentagon shapes.
A hexagon has six sides and six corners. ABee hive cell is the shape of a hexagon.
The next set of vocabulary words I will introduceare quadrilateral, pentagon, and hexagon.
