### 10slide p.p.

1. 1. Using Graphic Organizers to support ELL’s 3 rd grade Standard: 3.3 Geometry and measurement: Describe and analyze properties of 2-D shapes including perimeters
2. 2. How do they help? <ul><li>Graphic Organizers give students visual cues to support their learning. </li></ul><ul><li>They improve the structure and clarity of your thinking! </li></ul>
3. 3. Classification Chart: polygons
4. 4. Using the Polygon Classification Chart <ul><li>Columns: square, rectangle, quadrilateral, pentagon, hexagon, octagon, rhombus, trapezoid, parallelogram </li></ul><ul><li>Rows: sides, angles, perpendicular lines, and parallel lines </li></ul><ul><li>fill in the information with students while students use real examples and models. </li></ul><ul><li>(See slide 3) </li></ul>
6. 6. Using the Quadrilateral Diagram <ul><li>This chart shows that parallelograms, squares, rectangles, squares, rhombuses, trapezoids, and kites are ALL QUADRILATERALS. </li></ul><ul><li>It then breaks down to visually show that rhombuses, squares and rectangles are also all PARALLELOGRAMS. </li></ul><ul><li>The final step shows that a square is also a rectangle and a rhombus. BUT a rectangle is NOT a square ! </li></ul><ul><li>(see slide 5) </li></ul>
7. 7. Classification Chart: Triangles
8. 8. Using the Triangle Attribute chart <ul><li>Columns: equilateral triangle, isosceles triangle, scalene triangle, right triangle </li></ul><ul><li>Rows: sides, angles, perpendicular lines, parallel lines </li></ul><ul><li>Work with students to fill in the chart while using hands on materials and manipulates </li></ul><ul><li>(see slide 7) </li></ul>
9. 9. Diagram: Triangles
10. 10. Using the Triangle Comparison Chart <ul><li>This visual helps children to understand that triangles can fall into different classifications. </li></ul><ul><li>Scalene triangles can be right, obtuse, and acute. </li></ul><ul><li>Isosceles triangles can be right, obtuse and acute. </li></ul><ul><li>EQUILATERAL triangles are ALSO isosceles! </li></ul><ul><li>(see slide 9) </li></ul>
11. 11. Students then use charts for oral language practice using sentence frames: <ul><li>B - _________ have _________. Example: rectangles have 4 right angles. </li></ul><ul><li>I - ____________ can be described as _______________ . </li></ul><ul><li>Example: Octagons can be described as a polygon with 8 sides. </li></ul><ul><li>EA/A - ________ are characterized by several distinct features such as: ______ and _______. </li></ul><ul><li>Example: Equilateral triangles are characterized by several distinct features such as: all angles measure 60 degrees and all sides are equal. </li></ul>
