### Take Away

Pre-K-2
The following lesson introduces elementary students to subtraction. The objective is to create a link between students' experiences and mathematics. By the end of the lesson it is expected that students have a deep understanding of subtraction and how it relates to their world. This lesson was adapted from "Helping Students Understand Subtraction" by Anita Page, which appeared in the November 1994 Teaching Children Mathematics, Vol. 1, No. 3.

### Buttons! Buttons!

Pre-K-2
In the following lesson, students participate in activities in which they focus on connections between mathematics and children's literature. Specifically, students use clues to sort and classify buttons.

### Shapes and Poetry

Pre-K-2
Students read the poem "Shapes" from A Light in the Attic, by Shel Silverstein, and create their own illustration of the poem. In this lesson, students explore geometric figures and positional words.

### How Big Is a Foot?

Pre-K-2
In this lesson, students read the book How Big Is a Foot?, by Rolf Myller. They then create non-standard units (using their own footprints) and use them to make "beds." As a result, students explore the need for a standard unit of measure.

### Graphing Trash Material

Pre-K-2
In this lesson, students participate in activities in which they investigate the data in connection with recyclable materials and develop plans to help the environment.

### Toy-Shop Numbers

Pre-K-2
A toy-shop theme is used to help stimulate and generate discussion about numbers. Students use examples from a toy-shop to identify real-world uses of numbers and to write stories about those numbers.

### Create a House Number

Pre-K-2
This lesson focuses on forming 3-digit house numbers to meet specific requirements. Careful reading of information and understanding of mathematical language are important to finding appropriate solutions. Using the problem-solving strategies of looking for patterns and establishing an organized list will aid students in finding all the possible solution sets.

### Numbers and Me

Pre-K-2
In this lesson, students participate in activities in which they focus on the uses of numbers. The activities explore how students use numbers in school and every day settings as a way for students and the teacher to get to know each other at the beginning of the school year.

### What’s Next?

3-5
Students begin their study of growing patterns by making linear patterns with pattern block shapes using several pattern cores. They extend a partner’s pattern and find the missing element in a pattern.

### Looking Back and Moving Forward

3-5
In this final lesson of the Unit, students use logical thinking to create, identify, extend, and translate patterns. They make patterns with numbers and shapes and explore patterns in a variety of mathematical contexts.
