# Well That's Different!

Lesson 4 of 10

## Objective: SWBAT find different combinations of shapes that fill the same area. SWBAT identify how shapes can be combined to make other shapes.

### Thomas Young

## Big Idea: Finding different combinations to cover a given pattern block is the idea of the day. Students will create pattern block shapes using other pattern blocks.

#### Warm Up

*5 min*

Follow the established Quick Flash Routine and show the students Shape 1. After the students draw it, have them describe the shape. Repeat with shapes 7 & 8.

I start by telling the students that I want to challenge them today. I want to see how many different ways they can fill some of the pattern blocks that we have been working with. I first have each of the students grab a blue rhombus from the pile of shapes. I then ask if anyone can tell me the name of the shape? I then ask if anyone can make this shape using other pattern blocks? Once they do, I want them to put their thumb on their chin to show me they are ready. I ask students to share the way (there is only 1 in this case) they were able to replicate the rhombus. I then record the combination (of two green triangles) on a piece of poster paper (CCSS.MATH.CONTENT.1.G.A.2). I continue this same routine for the trapezoid and the hexagon. Each time I am recording the different ways that each shape can be made. The students are "making sense of quantities (in this case number of shapes) and their relationships in problem situations (**CCSS.Math.Practice.MP2**)."

When I am done, I will end the discussion with some questions about the hexagon:

1. What do you think is the most blocks that you can use to make a hexagon?

2. Which shapes would you use?

3. Why do you think that this is the most blocks that will fit?

#### Center Time

*40 min*

The goal of center time is for the students to work with pattern blocks in a variety of ways. These activities will be available over the next few lessons Students can choose which activity he/she wants to do based in interest. The students are using pattern blocks as a mathematical tool, to solve designs and fill in outlines, throughout all of these activities (**CCSS.Math.Practice.MP5**)

Center Time Choices:

1. **How Many Ways?**: This activity was introduced in a previous lesson.

2. **Fun With Pattern Blocks**: This activity was introduced in a previous lesson. You will have to print the Fun With Pattern Block Template and create 4 new designs. Again read through the description, in the link above, to learn how to do this. As you create each sheet label it a new number. There is a spot to do this near the top of the template.

3. **How Many Pattern Blocks?**: This activity was introduced in a previous lesson.

#### Extra Practice

*5 min*

Students should complete the practice sheet (see section resource). The equations on this sheet require the students solve for unknown addends (CCSS.Math.Content.1.OA.D.8). I have included a photo (in lesson resource) of how I adapted the activity for one child. I left a container of cubes on her table and didn't say anything about them. She chose to use them to help her with the addition equations. There is also a picture of a completed sheet by a student.
