Unit Description
Age/Grade Level | K |
Name of the unit | Developing Number Sense: Exploring Numbers One through Twenty |
Domain (e.g., Numbering, numerical relation, or arithmetic reasoning; or other) | Counting and Cardinality |
Unit Goals | To understand the relationship between numbers and quantities up to 20; connect counting to cardinality. |
What each lesson is about?How are the lessons related? | Research by Baroody, Li and Lai (2008) and Clements and Sarama (2014) suggest that Kindergarten children are great at rote counting, as indicated in questions like “Who has More?’ or “Are there enough?” This ability and experience set the foundation for fostering an understanding of number concepts and rational counting. Based on this research, each lesson in this unit will include meaningful activities that requires students to orally demonstrate an ability to count and represent numbers in quantities. For example, count 1,2,3 and use beads to represent the quantity 1, 2, and 3. Students will learn how to count and include quantities to match. The lessons are further related as they emphasize the development of numbers up to 20, consider number names and counting sequences, and show number relationships through comparisons of quantities. All three lessons in this unit will follow the Common Core State Standards-Mathematics and the New York Engage Next Generation Learning Standards: CCSS.MATH.K.CC. A. and CCSS.MATH.K.CC. A.2 Knowing number names and the counting sequence (e.g., match counting with objects.Counting to tell the number of objects (recognizing that each number is 1 more than the previous number).Writing numbers from 0-20, and comparing numbers (e.g., 1 less than, 1 more than, or same as/equal to). |
This Unit and its lessons are related to Chapter 4, pp. 55-59 of the textbook, Teaching Student-Centered Mathematics: Developmentally Appropriate Instructions for Grades PreK-2. All 3 lessons follow the three-phase lesson format discussed in Chapter 2 (pp.32-35) of the textbook by Van de Walle et al. (2018). Teaching Student-Centered Mathematics: Developmentally Appropriate Instructions for Grades PreK-2.Parallel and open tasks are included in the lessons. Problem-based activities are included by providing engaging tasks to help students develop understanding of Number Sense, counting from 1-10. According to Baroody, Li and Lai (2008) and Clements and Sarama (2014), providing children with opportunities to develop the concepts of “Who has More?’ or “Are there enough?” set a baseline for developing understanding of number concepts and rational counting. Meaningful counting activities require students to demonstrate verbal counting ability by saying “one, to, three…” this must be followed by the students to connect this sequence with a one-to-one correspondence (Clements & Sarama, 2014). Furthermore, knowing that children will learn how to count (i.e., match counting) before they understand the cardinality principle requires the teacher to provide practice in both areas (Fosnot & Dolk, 2001). Songs, rhymes, and activities that appeal to visual, auditory, and kinesthetic learners are included in the unit and supported by Van de Walle et al. (2018). Brief description of each lesson: Lesson 1: Knowing number names and the counting sequence focuses on developing rational counting by reviewing rote counting and providing opportunities for students to understand that the numbers they can recite represent quantities. Games, rhythm, and songs will be integrated in this lesson to meet the diverse needs of an inclusive classroom as they name and count numbers up to 10 making the one-to-one correspondence (CCSS.MATH.K.CC.A.1; CCSS.MATH.K.CC.A.2). Lesson 2: Counting to tell the number of objects includes activities such as “count forward beginning from a given number within the known sequence” (begin at 1 and from any number in a given set) CCSS.MATH.K.CC.A.2). These students have been working with the numbers 1-10 and knows the cardinality of numbers (last number counted names the set or answers the question “How many?”. In this lesson we will check for instant recognition of the number of objects in a set (subitizing) using dot cards or online interactive Dot cards. Primarily, the focus will be on developing understanding of the relationship between numbers and quantities and to connect counting to cardinality (CCSS.MATH.K.CC.B.4.A; CCSS.MATH.K.CC.B.4) Lesson 3: Writing numbers from 0-20. This lesson begins by reviewing rational counting (using one-to-one correspondence to find total numbers) and conservation of numbers and extending to writing matching numerals from 0 -20. Numeral writing includes tracing over numerals, making numerals from playdough, tracing them in the sand provided in the play area, and writing them on the interactive board or in the air. Students will engage in games and songs. For e.g., “We Count Our Fruits” is sung to the tune of Mary Had a Little Lamb. As they count objects and write up to 10. The teacher will include sequential activities such as “Act it out”, “Hands-on”, “Rhyming”, and “Count and Write” to support students writing efforts (CCSS.MATH.K.CC.A.3). Lesson 4: Comparing numbers. This lesson builds on students’ ability to count objects in an organized way and tell “How many are in this group?”. If asked to show you how old they are they can hold up 5 fingers. They may be able to write the matching numeral and say the number that comes before or after an identified number. Primarily, students are engaged in activities such as comparing numbers of objects in one group to the number of objects in another group by using matching and counting strategies (e.g., 5 is greater than 4 by 1, 4 is less than 5 by 1, or five parrots in this set is equal to a set of 5 objects) (CCSS.MATH.K.CC.B.4.C; CCSS.MATH.K.CC.B.5). | |
