Unit 12
Energizers (5 min)
Play thee cubes, cones, cylinders, and spheres book/video below and have students identify the shapes that they see. You can pause and ask students to justify using formal language.
Energizer with a song about three dimensional shapes as shown below. Pyramid is not an expectation for kindergarten so do not focus on this in the lesson but can be included in the energizer.Opening:
- Use the Chatterpix activity described below as an opener for your class. If you are not comfortable with the chatterpix activity, students can take pictures of the shapes that they found and use sentence stems to write "I can see a _______"
- Or use the Little Miss Geometry Activity as seen in the video below using three dimensional shapes or an assortment of two- and three-dimensional shapes:
Optional Unit 12 Activities
Play Dough Three-Dimensional Shapes
Students will use playdoh to create models of 3-D shapes.
Guide students in creating one shape at a time using their playdoh.
Some of these shapes are a little bit tricky to make. Tell students that it’s fine to try more than once. If they need to squish up their Playdoh and start again it’s no big deal. Most of us aren’t perfect at doing something the first time around.
Having the shapes in their hands gives students a great opportunity to count the faces, edges, and vertices.
As the models are created and the attributes are discussed, create a class anchor chart to record the attributes of the shapes.

Extended Talking Points:
What happens if we make our cylinder long and skinny? Does it still meet all the rules to be called a cylinder?
What happens if we do the same thing to our cube? Does it still meet all the rules to be called a cube?
2- and 3-D Sort
Place students in groups of 4 or 5.
Give each group a box with a collection of items. (See below for box suggestions)
Ask groups to examine the items and sort/group them how they see fit. Teacher may choose to have students label each group with how the objects were classified (i.e. objects that roll).
After groups finish sorting, they will alert the teacher.
Teacher will conference with the group to determine how they sorted their items and why.
If time permits, teacher will ask the group to try and resort their items another way.
Once all groups have sorted and justified for teacher, groups will rotate to a new table with a new box and do steps 3-5 again.
Box Suggestions:
Box 1: Small ball, golf ball, cylinder geo-solid, tube of chapstick, coin, ice cream cone, cotton round, foil from yogurt, circle counter, circle die-cut, sphere geo-solid, cone geo-solid, poker chip, etc. (could sort by things that roll, shapes with a circle, 2D vs. 3D, or real-world vs. non real-world)
Box 2: Photograph, playing card, envelope, rectangular prism geo-solid, small mirror, rectangle die-cut, pink rubber school eraser, square pyramid, small square box, square die-cut, sticky note, square colored tile, etc. (could sort by 3D vs 3D, squares vs. rectangles, real-world vs non real-world, etc.)
Box 3: Triangle cut-outs (right, acute, obtuse), square pyramid geo-solid, green pattern block triangle, square die-cut, small square box, pack of sticky notes, cube geo-solid, etc (could sort by 2D vs. 3D, real-world vs. non real-world, squares vs. triangles, etc.)
Box 4: This box could be a mix of similar items in the other 3 boxes (it would be interesting to see the different ways that students decide to sort the items.)Shape Hunt with Chatter Pix
- Students look for shapes around the room and take a picture of the shape they found.
- Using Chatterpix, students then can use the sentence stem, "I can see a" have the students pause here as they count backwards from 10 to 0 in their head before saying the shape that they made. This will allow you to use the the kids chatterpix images as an energizer!
- never used chatterpix? Request a DLC to come and help you with this lesson!
Feel & Write
ex: Box 3 is a cube.
Box 2 is a cylinder.
Pattern Barrier Game - with three-dimensional
This game was featured in the last unit for two-dimensional shapes but can be recycled and used with three-dimensional shapes.
Students use a grid and put a divider to separate their grid from their partners grid.
Partner A places shapes in the grid in front of them.
Partner A then uses formal geometric language to describe attributes of the shape goes in the grid spaces.
As a challenge, students can name only the attributes without being able to use the actual name of the shape.
Remove the divider to see if the grids match.

Shape Headbands
This time have the students find the three-dimensional shapes in newspapers, magazines, or taking pictures around the classroom or sending a picture of something they found from home. The pictures can be cut out and glued onto cards for the game. The student places shape or real object cards on their headband. The student wearing the headband has to guess the shape while their partner gives clues about the shape (use sentence stems if needed).
Literature Connection:
1. Guided Math
https://drive.google.com/open?id=1RY8QPnB34O5EuQKTwCznmqEgTTPr5V-kSogbS3s2T8g
3. Review/Preview:
- Review real object graphs and add in coins.
- Place coins in a pot.
- Students use a soup ladle to scoop out a collection of coins.
- The students then create a real object graph with the coins.
- Students can write a sentence using a sentence stem about their graph or use chatterpix and take a picture telling about their graph.
Fluency:
- This is a great opportunity to use any of the activities listed in the previous content previews that your students need additional practice with.
- I love math (Group of students, One student walks around and plays a round with each student, then sits down and next student goes)
- Salute (one more, one less than your number)
- Rolling dice (double, sum to 10, ten more, roll 2 and build a two digit number)
- Draw a card, build a number with manipulatives, draw, and write the number.
Closing:
- Class Share with predictable chart
- Class Journal
- Personal journal
- Partner talks
- Self assessment
