What educators are saying

I loved how this resource challenged students to really think about the attributes of the shape and then categorize it!

Geometry is one of the hardest topics for many teachers to teach--and textbooks rarely get at the deep thinking needed to help student master basic geometry skills as well as the thinking and reasoning needed to be proficent. This resource is a low ink, ready-to-print set of quality geometry math sorts with full color pictures and directions!

So what are concept sorts? Many people use "sorts" with their spelling or word work programs, but sorting and categorizing can be extremely effective learning strategies for MANY areas! I have found sorts to be particularly effective in my math instruction, and I am excited to offer some of these sorts to you! If you are unfamiliar with how sorts are used, I have included a full blog post with photos to help get you started!

So...what's included in THIS geometry edition?

1. Everything you need to do 5 different sorts related to geometry concepts. The concepts covered are:

  • “Is it a polygon? (This sort focuses on getting students to recognize the characteristics of polygons)

  • *Is it a line? What kind of line? (This sort helps students sort lines that are parallel, perpendicular, intersecting, and “other”)

  • *Quadrilaterals (This sort asks students to classify quadrilaterals by properties. It can be done multiple times in multiple ways!)

  • *Symmetry (This sort asks students to identify shapes by the number of lines of symmetry.)

  • *Triangle Types (This sort asks students to classify triangles by their angle size)

2. The blog post with photos that explains EXACTLY how I completed a sort with my own students. Feel free to get creative and try different approaches—but I have given one highly effective and efficient way to do this. This method can be used for ANY of my math sorts.

3. A “Show What You Know” sheet that follows the rule of the sort. Use as independent practice or as an assessment after you have done a sort to see what the students know and what they still need to learn. Many of these also ask students to explain their thinking—a key part of the CCSS!

4. A page of blank cards if you wish to extend the learning by having students create MORE examples that go in each category. This is a great way to differentiate for more capable learners! See each sort for other differentiation hints!

5. No answer key. Why? The important part about doing these sorts is the discussion rather than making sure every answer is instantly correct. Let the students discuss, prove their ideas, and develop understanding!

6. A CCSS alignment sheet to show how these sorts align to the grades 4-5 CCSS.

I hope you find the resource thorough, relevant, and engaging--and that it will push your students to increase the depth of their understanding and their mathematical practices as well.

to see state-specific standards (only available in the US).
Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.
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. Identify line-symmetric figures and draw lines of symmetry.
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.
