The Shape of Things

We read The Shape of Things by Dayle Ann Dodds to introduce the attributes of shapes. After reading the students were each given a random shape that they had to turn into a real life object, just as in the book. They then told me about their shape which I typed following the style of the book. The pictures were bound together in a class book for them to read during Daily 5 and Math Tubbing. I believe it is important for students to be exposed to math vocabulary in all subjects.

Shape Attributes

The students have recently been learning about the various attributes of shapes. They worked on various lessons including sorting shapes into 2D and 3D shapes. They also identified the number of edges, vertices, and faces of 3D shapes using garage sale dot stickers (it helps them identify which they've already counted). Additionally, they sorted cards of various 2D and 3D shapes into categories such as rolls, has 3 or more faces, has vertices, etc. They also made various 3D shapes out of playdough.

The Shape of Things

We recently read The Shape of Things to review shapes. After reading, the students were given a 2D shape and asked to turn that shape into a picture, like the examples in the book. The students then wrote sentences (with my help on the typing) about their pictures following the format of the book. Their work will be bound together as a classroom book. The students love reading what their friends write.

Shape Clowns

The students created clowns using a variety of 2D shapes. As they worked we discussed the attributes of each shape.

Shapes Around Us

After charting the attributes of 2D shapes, the students created posters to draw real-life objects that were in the same shapes.

Attributes of 2D Shapes

As we learned about the attributes of 2D shapes the students worked in cooperative groups to show examples and non-examples of circles, triangles, squares, and square rectangles. When sorting they had to verbally justify how they knew what were examples and what were non-examples by explaining the specific shape's attributes such as how many sides and vertices the shape has. The students then went on "gallery walks" to see how their classmates had sorted their shapes.

Pattern Block Fish

To review patterns and shapes, we read Pattern Fish by Trudy Harris and then the students created their own pattern fish. Fellow teachers, I received this particular pattern fish template from a former teammate but you can find similar patterns at PreKinders. The students had to find two different ways to fill in the pattern fish with foam pattern blocks and then they had to choose their favorite one to create with paper pattern blocks. The students then counted and graphed how many of each type of pattern block they used. The students compared the various different ways the fish could be filled using pattern blocks.

Playdough 3D Shapes

Kids love playdough! So, if you are looking for a way to keep them engaged in a lesson, give them playdough. While doing a lesson on 3D shapes I wanted the students to have concrete examples of how 3D shapes are similar and different. The students first made a sphere by rolling the playdough into a ball. We talked about how the sphere would roll because it was curved and had not vertices. They then flattened the top and sides a little bit to create a cube. We talked about when the sides were flattened the shape would not longer roll and that vertices and edges had formed. They then counted the number of edges and vertices. The students then flattened the top a little more to make a rectangular prism. They noticed that the edges and vertices remained the same but now the shape was longer. They connected back to prior learning about squares and square rectangles and their similar attributes. they then rolled the rectangular prism like a "snake" to turn it into a cylinder. They discovered that this shape would roll because it was now curved and the edges and vertices were gone. They then rolled just one end of the cylinder into a point to make a cone. They discussed how this shape would roll because it had a circular base but could only roll if it was on its side. They really seemed to understand the attributes of the shapes with this hands on lesson.

3D Shape Models

To help the students understand how many faces, edges, and vertices that cubes and rectangular prisms had, the students traced the sides onto construction paper. After they traced a side, they put a colored dot sticker on that side to help them remember they had already traced and counted that side. They had to follow step-by-step instructions on where to trace the sides because once they were finished, they cut out the shapes and taped them together to make the 3D models. We then counted the corners and edges.

The Shape of Things

Last week we read The Shape of Things during our study of two-dimensional shapes. To help the students realize that shapes make up our world, they created pictures based off of either a circle or a square rectangle. They are amazing! Their pictures are currently on display in the hallway but will soon be put together as a class book for our class library.
