The No-Prep Geometry Boom Cards You NEED for Your Students

Must-Have Geometry Boom Cards for 4th and 5th Grade Blog Post

I’m all for finding activities that make math review actually fun for students! And when it comes to teaching geometry, with all the definitions and formulas that 4th and 5th graders need to know, this is definitely a unit that needs it! In this post, let’s dig into using my favorite geometry Boom cards for practice and review!

If you’re new to Boom, you can learn more about how these digital, self-checking task cards work in this post. (You can also save 10% on a new membership if you use my referral link, which may help me earn points for a referral prize.)

Using Boom Cards in Your Geometry Unit

Boom cards are perfect for practice, review, remediation, enrichment, and even assessment. You can use them whole-class, with small math groups, in guided math rotations, for test prep, and even assign them for homework.

You can create your own Boom cards to use with your students, so the options are really endless for what geometry skills you want to hit. But if you’re looking for no-prep, standards-based decks, I’ve got you covered!

The geometry Boom cards I’ve created cover basic vocabulary, plane and solid figures, quadrilaterals, angles, triangles, geometric transformations, and combining/subdividing polygons.

Basic Geometry Terms

By 3rd and 4th grade, a lot of geometry vocabulary has already been introduced, but students still often struggle with their definitions – especially when you introduce symbolic notation.

This Boom deck helps students differentiate among the different terms so they can get that down before moving on to more complicated geometry standards. They will:

  • identify and describe points, lines, line segments, rays, and angles, including endpoints and vertices
  • identify and describe intersecting, parallel, and perpendicular lines

And like all Boom cards decks, students get immediate feedback and you get progress monitoring!

Solid Figures

3D figures won’t be new to bigger kids, but now students really need to have their characteristics down. Think angles, vertices, edges, and the number and shape of faces.

That’s a lot to remember! These 16 geometry Boom cards are perfect to practice identifying, describing, and comparing solid figures according to their characteristics.

Classifying Quadrilaterals

Oh my gosh. If there were ever a standard I’d want to get rid of, it’s this one!! Parallelograms, rectangles, squares, rhombi, and trapezoids, oh my!

Identifying and classifying quadrilaterals is tricky business and students definitely need all the practice they can get! This is an especially good standard to use Boom cards with because it makes a painful topic more engaging to practice.

With these 20 Boom cards, students will review definitions and properties of quadrilaterals, including geometric markings for parallel sides, congruent sides, and right angles.

Classifying and Measuring Angles

I think angles are really fun to teach, but I know some teachers who loathe protractors. It definitely takes a lot of practice for students to line them up and read them correctly.

And since measuring angles will pop up on spring math tests, it’s really helpful to practice using a protractor on a computer.

These angles Boom cards give students practice with:

  • classifying angles as right, acute, obtuse, or straight
  • measuring right, acute, obtuse, and straight angles
  • using addition and subtraction to determine unknown angle measures on a diagram

Classifying Types of Triangles and Determining Angle Measures

By 4th and 5th grade, students need to know way more about triangles than that they have 3 sides. There’s quite a lot of content to teach for the triangle standards and many students are shocked to see that they have to “do math” in geometry!


Since there are a lot of components to this standard, I broke it up into two decks to target the different areas:

  • classifying triangles as right, acute, or obtuse and as equilateral, scalene, or isosceles
  • comparing/contrasting the properties of triangles
  • identifying congruent sides and right angles using geometric markings
  • determining an unknown angle measure in a triangle

Geometric Transformations

I LOVE the geometric transformations unit and it’s so much fun to review with Boom cards because students can drag and drop objects to show translations, reflections, and rotations.

Like all Boom cards, there are so many ways to use these during your geometry unit for engaging math review!

Combining & Subdividing Polygons

Here in Virginia, not only do students have to know the different plane figures, but they also need to understand how figures can be joined or divided to make different polygons.

Visualizing this can be challenging for some students, so it helps to have a lot of hands-on practice with manipulatives. And since they’ll also need to master this skill using drawings of polygons, these 16 Boom cards are a helpful tool to have on hand.

As always, I create my Boom cards to be standards-based, to use TEI skills, to be engaging for students, and to save teachers time. Let me know what other geometry Boom cards you’d like to see in my shop!
