Learning Goal: Build conceptual and procedural fluency with partitioning segments and calculating midpoints.

Classwork

• Estimation – Midpoint
• Warm Up
• Ratios Re-Engage
• Notes
• Ungraded Formative Assessment / Midpoint Shapes

Standards

• Common Core
  • HSG.GPE.B.6 – Find the point on a directed line segment between two given points that partitions the segment in a given ratio.
• TEKS
  • G.2(A) – determine the coordinates of a point that is a given fractional distance less than one from one end of a line segment to the other in one- and two-dimensional coordinate systems, including finding the midpoint
  • G.2(B) – derive and use the distance, slope, and midpoint formulas to verify geometric relationships, including congruence of segments and parallelism or perpendicularity of pairs of lines
