twHere are some of my favorite geometry activities:
1. Start With Shapes
I like to have students start with shapes they've known since they were tiny, like triangles, squares, and circles. We draw these on whiteboards as a whole class. Next we draw the more advanced shapes like pentagons, hexagons, octagons, trapezoids, and even the rhombus! This brings us to a discussion of polygons and we can classify shapes that way.
Besides whiteboards, there are lots of ways for kids to work with shapes, like Popsicle sticks (which are also great to use to illustrate lines like parallel, intersecting, and perpendicular), LEGOS, Geoboards, and even clothespins which can be clipped together.
2. Marshmallow Geometry
I like this activity because any time you add food, kids are all in! Using marshmallows and toothpicks, kids can make simple 2-D shapes, and also 3-D shapes. Plus, this activity is the perfect place to emphasize vertices since each time you add a marshmallow, you place it at a corner. If you have food allergies or school regulations which prohibit food, you can substitute the marshmallows for Play-Doh.
3. Use an Anchor Chart
Once students have had lots of exploration time with shapes, it's time to discuss their attributes. I like to actually make this anchor chart with the kids' help. I explain how it will be organized, from the smallest number of sides to the greatest. We also notice patterns of sides and vertices as we create it. I do ask kids for examples of shapes, and sometimes they get really creative with this!
4. Go on a Shape Scavenger Hunt
This is an activity that is great to do with some parent helpers if you have any. I like to send iPad cameras with each group, clipboards and pencils, and a record sheet. Kids record the shape that was found, the type of object it was, and where it was found. It's really fun to see what shapes they're able to find while walking around the school campus!
I am a huge art proponent so I add art wherever it fits in. Geometry is a great time to do either geometric animals, robots, or people. I usually choose one of those categories but really you could make it a wide open project too!
I shared another fun geometric art activity on a blog post I wrote called Incorporating Art in the Classroom. This one is from Literacy Loves Company. As a follow up to geometric lessons on lines and angles, I cut polygons from white construction paper for each child. I have kids use rulers and sharpies and follow my step by step directions of drawing lines and then finding obtuse angles, right angles, perpendicular lines, and so on. After the lesson is done, kids add color to these, making it a really fun art piece.
6. Add Some Kinesthetic Learning
Kids need movement and it's easy to add some movement with this unit. For this activity, students will be on the floor working with a partner to make different kinds of lines (parallel, intersecting, and perpendicular), shapes, and angles (right, acute, and obtuse) using their bodies. An alternative is to have kids stand up and use their arms to illustrate these geometric concepts.
Another kinesthetic activity is to gather Chinese jump ropes or packages of sewing elastic. If you use elastic, one package is enough for one small group of 5 - 6 kids. The idea is to have students use the elastic as a group to make the shapes you call out (types of triangles are especially good) or types of angles. Different kinds of lines can also be made if two groups work together.
7. Add Some Task Cards and Games
Task cards are one of my go-to tools! Kids love the game-like format and I know that they're getting really focused learning on whatever math concept we're working on. I have used them as centers/stations, for whole class math time, for one on one, and as exit slips.

I love it when I can tie reading into math too! The books above are some of my favorite mentor texts for geometry. I love all of the visual examples included.
9. Use Music
I just found these songs by Numberock on YouTube and they are perfect for this unit! Really great pictures and catchy tunes:
Parallel, Perpendicular and Intersecting Lines
Angles
Types of Triangles
10. Practice Angles
Seriously, next to long division, measuring angles is probably the most difficult math skill students will face in the elementary years! It doesn't help too that it is introduced in fourth grade in common core and then not even mentioned in 5th grade standards. Oh well!
One activity that helps is to have kids use graph paper and write their first name in all capital block letters. Students can measure any angles created by the intersection of the letter's lines.
Another favorite activity for practicing angles is to take tape and make different lines, which create angles on a desk, table, or even on sheets of butcher paper. Kids use protractors to measure angles and then write with expos (or markers on the butcher paper) right on the desks/tables! Great way to add some fun to this difficult concept!
Hope you've found at least a few ideas you can use for your geometry unit! I did want to let you know that I have Math Task Card Bundles for every grade from 3rd - 5th. Each bundle has 30 sets of 32 task cards that cover ALL STANDARDS (CCSS) for those grades. I love prepping them at the beginning of the year and then grabbing whatever concept we're working on for some added practice.
