# Chapter 1: Number

### Each topic in this chapter engages students in the following ways:

EXPLORE: Videos allow students to explore number concepts to lay a beginning foundation for developing a strong number sense.

PRACTICE: Students practice the key ideas.

REFLECT: Students consolidate learning by journaling.

## Topic 1 Counting Sequence

The counting sequence is practiced through games and songs that provide a rhythmic sequence that will eventually be memorized.  Songs such as “This Old Man” and “One, Two, Buckle My Shoe” provide engaging experiences to practice the counting sequence.  A stable counting sequence is necessary for counting sets of objects.

## Topic 2 Sorting

Sorting is a necessary component to answering questions such as “how many”?  In order for students to answer how many items,  first they need to sort a collection of items into sets and eventually will compare and count these collections.  We develop these ideas through activities that establish vocabulary of same and different.  We sort items each day without ever thinking about it.  Providing activities that require sorting will help lay foundational ideas for answering questions such as “how many?”   an essential step in developing number sense.

## Topic 3 Numbers to 10

After creating sets of items students begin to associate the numeral with a quantity in communicating ideas.  These ideas include answering how many, which set has more, how much more?  Mathodology incorporates activities to build number sense by using the playing cards.  Students practice representing quantities in multiple ways creating flexibility in the way they represent and manipulate numbers.  These initial activities create the beginning layer for developing number sense.

## Topic 4 Ordinal Numbers

Ordinal Numbers are used in describing position in a line as well as sequencing events.  Students come to learn that counting “1” of an item may not seem like a lot, but coming in 1st position may take on a new meaning.  Expanding the way we use numbers is critical in developing number sense.  When does 5 of something feel small and at other times feels so large?

Students use everyday activities to build sense of using numbers in a different way.

## Topic 5 Numbers to 20

Numbers to 20 begins to focus on two-digit numbers and the role of 10 in both counting quantities and writing numbers.  Activities allow students to see teen numbers as “10 and more” laying the initial foundation in place-value ideas.  The ability to compose and decompose numbers into parts is an essential understanding in developing number sense.
