What we like about this lesson
Mathematically:
- Allows students to begin visualizing the teen numbers as ten ones and some further ones (K.NBT.A.1)
- Gives students opportunities to practice "counting on" in a quick and efficient way during fluency practice (K.CC.A.2)
- Lays the foundations for students to reason abstractly and quantitatively about teen numbers (MP.2)
In the classroom:
- Uses multiple concrete representations and visual models to make the mathematics explicit
- Allows for whole group, partner, and individual work in one lesson
- Prompts students to share their developing thinking and understanding (Student Debrief and throughout lessons)
- Provides opportunities and suggestions for differentiation
- Gives formal and informal opportunities for teachers to check for understanding
How does this lesson exemplify the instructional Shifts required by CCSSM?
Focus Belongs to the major work of kindergarten Coherence Lays the foundation for place value work in first grade (1.NBT.B.2) Rigor Conceptual Understanding: primary in this lesson (K.NBT.A.1)
Procedural Skill and Fluency: secondary in this lesson (K.CC.A.1)
Application: not addressed in this lesson
It's important to note that this sample lesson is just one of a 14-lesson unit called Numbers 10–20: Count to 100 by Ones and Tens. It is not intended for students to meet the full expectations of the grade-level standards addressed in these lessons through only this selected lesson. These sample lessons lay a strong foundation for the work that is to come in the unit. In the subsequent lessons, students begin to connect this knowledge (of ten ones and some further ones) to the teen numbers and writing those numerals.
The structure of these lessons and the unit/curriculum overall have some interesting aspects to highlight. The units make explicit the coherence within the fully developed curriculum. Each topic (a set of lessons) is connected to prior learning and also points to the next lesson that follows in the learning progression. Within individual lessons, there are a number of components that add to their strength including daily fluency practice, variety in questioning techniques, and daily opportunities for students to debrief about their learning.
