Geo.1 Constructions and Rigid Transformations. In this unit, students first informally explore geometric properties using straightedge and compass constructions. This allows them to …Lesson Narrative. This lesson establishes the straightedge and compass moves that students will use to perform various constructions. Students build on their previous understanding of circles as a set of points all equidistant from the center and line segments as a set of points on a line with two endpoints. Constructions are used in subsequent ...Problem 5. In the figure shown, angle 3 is congrent to angle 6. Select all statements that must be true. Lines and are parallel.

First, ask students to share what they noticed about their graphs. Next, display a table like the one in students’ books or devices and poll the class on the measurements they got for each square. If desired, give students 1–2 minutes to plot more points on their graph for the values they added to their tables.Unit Goals. Students learn about and use the relationship between multiplication and division, place value understanding, and the properties of operations to multiply and divide whole numbers within 100. They also represent and solve two-step word problems using the four operations.
The problems preview using the Pythagorean Theorem, which is a key idea in a subsequent lesson. They also preview finding all unknown values in right triangles, which is a key idea in a subsequent unit. Students have a chance to reason abstractly and quantitatively as they think about whether their answers make sense in context (MP2).Alg1.3 Two-variable Statistics. In grade 8, students informally constructed scatter plots and lines of fit, noticed linear patterns, and observed associations in categorical data using two-way tables. In this unit, students revisit two-way tables to find associations in categorical data using relative frequencies.
