Copyrighted by Elizabeth Hill, Tricks of the Trade 2013 What are we learning? Understand that shapes fit in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories. Copyrighted by Elizabeth Hill, Tricks of the Trade 2013

Copyrighted by Elizabeth Hill, Tricks of the Trade 2013 In Kid Terms I can identify, classify, and sort quadrilaterals by determining how quadrilaterals are alike and different. Copyrighted by Elizabeth Hill, Tricks of the Trade 2013

What types of angles can you spy? Which shapes have acute angles? Which have right angles? Which have obtuse angles? If you are not sure, you can use a piece of paper to help. The corners of paper are 90˚. Copyrighted by Elizabeth Hill, Tricks of the Trade 2013

Copyrighted by Elizabeth Hill, Tricks of the Trade 2013 Your turn Fold your paper into quarters. Draw and label the four types of angles. 3. Then call me over to check. *Don’t forget to use the Angle Chant Acute Obtuse Right Straight Copyrighted by Elizabeth Hill, Tricks of the Trade 2013

Two lines joined together at an end point. How do you describe an angle? Two lines joined together at an end point. Copyrighted by Elizabeth Hill, Tricks of the Trade 2013

What are the different ways lines could interact? Use two pencils to see the different ways you can lay them without just making a longer line or just 1 angle. They can lay side by side so that they will never touch They cross forming acute and obtuse angles. They cross forming right angles. Copyrighted by Elizabeth Hill, Tricks of the Trade 2013

Types of Lines Parallel Intersecting Perpendicular Lines lay side by side so they will NEVER cross. Lines cross to form acute & obtuse angles. Perpendicular Lines cross percectly to form right angles. Copyrighted by Elizabeth Hill, Tricks of the Trade 2013
