# Q4, W2: April 1st – 5th

Teacher Felicia Taylor Intensive Math 7th 30 Focus 4: Geometry
Standard(s) Taught

#### Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.

Learning Targets and Learning Criteria

Students are successful when they can…

• draw (freehand, with ruler and protractor, with technology) geometric shapes with given conditions.
• construct triangles from three measures of angles or sides.
• describe when angle measures determine a triangle (given angles equal 180).
• describe when side measures determine a unique triangle (a + b > c) or no triangle (a + b ? c).
• discover the two-dimensional shapes that result from slicing three-dimensional figures.
• develop three-dimensional visualization skills as the see the resulting two-dimensional shapes.
• explain the relationship between circumference and diameter of a circle using correct mathematical vocabulary.
• solve mathematical and real-world problems by applying the area of a circle and circumference formulas.
• explain the relationship between the circumference and area of a circle.
