### Target 1​

###### Lesson Type:

New

Geometry

:

Shape

Describe the 2D shapes that result from slicing 3D figures.

###### 1:

Visualize what shape will be the result from cutting a 3D solid.

###### 2:

Visualize horizontal, vertical, and diagonal cuts.

4th

###### Vocabulary:

Net, 3D shape, Properties, Vertices, Edges, Faces, Vertical, Horizontal, Diagonal, Cone, Sphere, Prism (Rectangular, Triangular, Hexagonal, Pentagonal, etc.) Pyramid (Square, Triangular, Pentagonal, etc.)

Activities:

1. Students looked at a variety of 3D shapes and identified then names of their shapes based on its properties.

2. After identifying the names of the shapes, students reviewed and discussed how many vertices, edges, and faces each 3D shape had.

3. Next, students cut out a variety of 3D shapes and placed each in the correct name. Then, cut out each net of the shape and placed if in the correct place.

4. Lastly, students were given paper dominoes that had pictures of real-world items, the shapes nets, pictures of 3D shapes, and descriptions that identifies different 3D shapes. Students needed to put together the pictures by matching it like dominoes.

## Absent Students:

### Target 2

:

###### 1:

Understand that angles can be composed or decomposed, using addition and subtraction.

4th

###### Vocabulary:

Composed, Decomposed, Missing angle, Unknown

Activities:

Students continued finding missing angles when given a few other known angles. For example, given a total of 120 degrees and one of the angles was 90 degrees, students needed to find the other angle's measurement.
