Symmetry for 4th Graders
By Brooke Wert
Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts.
[4.G.3-1.0] Lines of Symmetry - Common Core Standard
By Freckle education
Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts.
Math Antics - Points, Lines, & Planes
By mathanatics
Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
Recovering the Sequence of Transformations to Show Congruence or Similarity
By James Olsen
Directions: Two figures will be given. Determine if they are congruent or similar. Then state the sequence of transformations that exhibits the congruence or similarity. There is an error in this video!! In example 3, the first translation should be using vector BF (and not vector AF). This is aligned with the following Common Core State Standards for Mathematics: [8.G.2] Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them. [8.G.4] Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two- dimensional figures, describe a sequence that exhibits the similarity between them. [G.CO.5] Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence of transformations that will carry a given figure onto another. [G.SRT.2] Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar
[5.G.3-1.0] Attributes & Categories - Common Core Standard
By Front Row
Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.
[7.G.3-1.0] Slices of 3D Figures - Common Core Standard
By Freckle by Renaissance
Describe the two-dimensional figures that result from slicing three-dimensional figures as in plane sections of right rectangular prisms and right rectangular pyramids Front Row is a free, adaptive, Common Core aligned math program for teachers and students in kindergarten through eighth grade. Front Row allows students to practice math at their own pace - learning advanced concepts when they're ready and receiving remediation when they struggle. Front Row provides teachers with access to a detailed data dashboard and weekly email reports that show which standards are causing students difficulty, what small groups can be formed for interventions, and how their students are progressing in math.
