### Target 1​

###### Lesson Type:

Continuation

Geometry

:

Symmetry

Understand that a figure does not change in a symmetrical reflection, the only change is positional.

###### 1:

Relate a reflection to a mirror.

###### 2:

Experiment with a mirror to see that a figure's reflection is backwards.

###### 3:

Relate a reflection to a fold line, where an image will leave its impression on the other side, and that impression will be backwards (the fold line will create an image that has matching parts).

###### 4:

Identify the reflection of a given image.

2nd

###### Vocabulary:

Symmetry, Reflection

Activities:

• Students developed their understanding of symmetry. Students could create the image made with pattern blocks, but had some difficulty with making the reflection on the other side of the fold line. Students used mirrors to see the reflection of the given image. The mirror was used to take a closer look to determine where to place the pattern blocks to create the reflection.
• Students drew the missing half to complete the images in their workbook.    ### Home Exploration

### Target 2

:

###### 1:

Explain that symbols can be anything: a question mark, a blank space, a color, a shape. The symbol is just an indication of what needs to be solved.

###### 2:

Look closely at the problem to determine what needs to be solved, it is not always after the =.

2nd

###### Vocabulary:

Variables, Unknown

Activities:

Students developed their understanding of variables (unknown numbers). Students solved for the "unknown" in equations given the sum, difference, an addend, or minuend (the amount from which a quantity is subtracted). We talked about whether we needed to add or subtract to find the unknown. Ex. 8 - ? = 3. We start with 8, subtract an unknown amount, and end up with 3. OR Ex. 3 + ? = 6. We start with 3, then we add an unknown amount, and end up with 6.    ### Home Exploration
