EXPLAIN

STANDARDS Standard 7.G.1 Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale. Standard 7.G.2 Draw geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.

Standard 7.G.3 Describe the two-dimensional figures that result from slicing three-dimensional figures, as in plane sections of right rectangular prisms and right rectangular pyramids.

Standard 7.G.5 Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.

Standard 7.G.4 Know the formulas for the area and circumference of a circle and use them to solve problems; given an informal derivation of the relationship between circumference and area of a circle. THIS IS THE FIRST TIME STUDENTS WORK WITH CIRCLES

Standard 7.G.6 Solve real world and mathematical problems involving area, volume, and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.

END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS I can understand how scale applies to tasks such as reading a map. Language Supports: ●​ Vocabulary (scale, scale factor)

I can use understanding of area, surface area, and volume to solve real-world problems. Language Supports: ●​ Vocabulary (volume, surface area)

I can find the circumference and area of real-world objects and spaces. Language Supports: ●​ Vocabulary (circumference, area) DIFFERENTIATION IN ACTION Skill Building Lesson 2.1 - Take another look lesson.
