Unit 8

Putting It All Together

Unit Goals

Unit Narrative

In this unit, students apply their learning from the year, revisiting the major work and fluency goals of the grade.

Section A focuses on the concepts of counting and comparing. Section B highlights the presence of math in students' school community. Section C enables students to practice composing and decomposing numbers within 5, as well as adding and subtracting within 5. Section D focuses on composing and decomposing 10.

The sections in this unit are standalone sections, not required to be completed in order. The goal is to offer ample...

Section A

Section Goals

Section Narrative

In this section, students count and compare collections of up to 20 objects. The focus is on the count sequence up to 20 and using it to determine 1 more or 1 less than a given quantity or number, both with and without a context.

Compare the groups of objects.
Explain how you know which group has more objects.

There...

Section B

Section Goals

Section Narrative

In this section, students explore and describe the math around them. They participate in activities that allow them to notice, record, ask questions, and tell stories about math in their community.

First, students record quantities that they see in their school as they make their own number book. Next, they ask and answer their own mathematical questions, such as: “How...

Section C

Section Goals

Section Narrative

In this section, students develop fluency with adding and subtracting within 5. Repeated practice with different compositions of numbers to 5 prepares students to fluently find the values of addition and subtraction expressions.

Students use a variety of tools and representations for their work with the numbers 1–5.

For instance, they sort domino cards based on the number of dots...

Section D

Section Goals

Section Narrative

In this section, students work with 10 as a benchmark when working with numbers within 20. This work prepares them to add within 20 in grade 1, where students will be encouraged to make a ten.

The section begins with students composing and decomposing 10 in different ways and representing these compositions and decompositions with equations. Students then find the...
