TITLE : Unit 07: Number Relationships up to 99 SUGGESTED DURATION : 10 days

Unit Overview

Introduction
This unit bundles student expectations that address relationships and patterns in numbers including the sum of a multiple of 10 and a one-digit number, reciting numbers, skip counting, and numbers that are 10 more and 10 less than a given number. According to the Texas Education Agency, mathematical process standards including application, a problem-solving model, tools and techniques, communication, representations, relationships, and justifications should be integrated (when applicable) with content knowledge and skills so that students are prepared to use mathematics in everyday life, society, and the workplace.

Prior to this Unit
In Kindergarten, students recited numbers by tens up to 100. In Grade 1 Unit 06, students explored place value in order to understand numbers up to 99.

During this Unit
Students delve deeper into the place value system. Various representations (e.g., linking cubes, straw bundles, base-10 blocks, place value disks, hundreds charts, beaded number lines, and open number lines) are used to discover numerical patterns in the number system. Students use place value patterns to determine the sum up to 99 of a multiple of 10 and a one-digit number, as well as determine a number that is 10 more or 10 less than a given number. Students continue to develop the understanding of cardinal numbers, meaning numbers that name the quantity of objects in a set, and hierarchical inclusion, meaning each prior number in the counting sequence is included in the set as the set increases, as they recite numbers up to 99 forward and backward by ones and tens in addition to skip counting by 2s, 5s, and 10s.

After this Unit
In Unit 09, students will continue to explore place value and numerical relationships in larger numbers up to 120, as well as the relationship between skip counting patterns up to 120 and counting a collection of coins up to 120¢.

Additional Notes
In Grade 1, reciting numbers is identified within the Grade 1 Texas Response to Curriculum Focal Points (TxRCFP): Developing an understanding of place value. Determining the sum of a multiple of 10 and a one-digit number, determining numbers that are 10 more or 10 less than a given number, and skip counting are also identified within Grade 1 Texas Response to Curriculum Focal Points (TxRCFP): Developing an understanding of place value in addition to the Grade 1 Texas Response to Curriculum Focal Points (TxRCFP): Solving problems involving addition and subtraction. This unit is supporting the development of the Texas College and Career Readiness Standards (TxCCRS): I. Numeric Reasoning, VIII. Problem Solving and Reasoning, and IX. Communication and Representation.

Research
According to Teaching Children Mathematics, even students in grades two through five do not understand how the digits in a two-digit number relate to a picture of that many single objects. Drawing students’ attention to these connections in the early grades will help lead to later success (Ross, 2002). Research suggests that students’ abilities to understand various representations of numbers and to make connections among those representations are essential to success with mathematics (Hiebert & Carpenter, 2006).

MISCONCEPTIONS / UNDERDEVELOPED CONCEPTS

Misconceptions:

  • Some students may think when increasing or decreasing a number by a multiple of 10, the tens place is increasing or decreasing by 1 rather than understanding that a change of 1 in the tens place means a change by 1 group of 10.
  • Some students may think the pattern used to recite numbers backward is different than the pattern used to recite numbers forward rather than applying the same place value relationships to reciting forward or backward (e.g., if, when reciting numbers forward, the digit in the ones place increases by one, then when reciting numbers backward, the digit in the ones place will decrease by one, etc.).
  • Some students may think skip counting numbers in sequence is a memorization task rather than understanding that each number represents a group of objects and that each group of objects in the skip counting sequence represents a quantity of one group more than the previous number.

Underdeveloped Concepts:

  • Some students may be confused about the counting sequence for the numbers 11 – 15 and recite these numbers as “one-teen, two-teen, three-teen, four-teen, five-teen” rather than “eleven, twelve, thirteen, fourteen, fifteen.”
  • Although some students may be able to correctly recite numbers forward from 0 – 99, they may have difficulty beginning with a number other than 0.
  • Some students may have difficulty remembering which multiple of 10 follows a number with a 9 in the ones place (e.g., 40 comes after 39, 30 comes after 29, 20 comes after 19, etc.).

Unit Vocabulary

  • Number sentence – a mathematical statement composed of numbers, and/or an unknown(s), and/or an operator(s), and an equality or inequality symbol
  • Place value – the value of a digit as determined by its location in a number such as ones, tens, etc.

ELLs may be at the beginning, intermediate, advanced, or advanced high stage of English language acquisition in listening. In order for the ELL to meet grade-level learning expectations across the foundation and enrichment curriculum, all instruction delivered in English must be linguistically accommodated (communicated, sequenced, and scaffolded) commensurate with the student's level of English language proficiency. The student is expected to:
ELPS.c.2A distinguish sounds and intonation patterns of English with increasing ease
ELPS.c.2B recognize elements of the English sound system in newly acquired vocabulary such as long and short vowels, silent letters, and consonant clusters
ELPS.c.2C learn new language structures, expressions, and basic and academic vocabulary heard during classroom instruction and interactions

ELPS.c.3 The ELL speaks in a variety of modes for a variety of purposes with an awareness of different language registers (formal/informal) using vocabulary with increasing fluency and accuracy in language arts and all content areas. ELLs may be at the beginning, intermediate, advanced, or advanced high stage of English language acquisition in speaking. In order for the ELL to meet grade-level learning expectations across the foundation and enrichment curriculum, all instruction delivered in English must be linguistically accommodated (communicated, sequenced, and scaffolded) commensurate with the student's level of English language proficiency. The student is expected to:
ELPS.c.3A practice producing sounds of newly acquired vocabulary such as long and short vowels, silent letters, and consonant clusters to pronounce English words in a manner that is increasingly comprehensible
ELPS.c.3B expand and internalize initial English vocabulary by learning and using high-frequency English words necessary for identifying and describing people, places, and objects, by retelling simple stories and basic information represented or supported by pictures, and by learning and using routine language needed for classroom communication
ELPS.c.3C speak using a variety of grammatical structures, sentence lengths, sentence types, and connecting words with increasing accuracy and ease as more English is acquired
ELPS.c.3D speak using grade-level content area vocabulary in context to internalize new English words and build academic language proficiency
ELPS.c.3E share information in cooperative learning interactions
ELPS.c.3F ask and give information ranging from using a very limited bank of high-frequency, high-need, concrete vocabulary, including key words and expressions needed for basic communication in academic and social contexts, to using abstract and content-based vocabulary during extended speaking assignments
ELPS.c.3G express opinions, ideas, and feelings ranging from communicating single words and short phrases to participating in extended discussions on a variety of social and grade-appropriate academic topics
ELPS.c.3H narrate, describe, and explain with increasing specificity and detail as more English is acquired

ELPS.c.3J respond orally to information presented in a wide variety of print, electronic, audio, and visual media to build and reinforce concept and language attainment.
ELPS.c.4 The ELL reads a variety of texts for a variety of purposes with an increasing level of comprehension in all content areas. ELLs may be at the beginning, intermediate, advanced, or advanced high stage of English language acquisition in reading. In order for the ELL to meet grade-level learning expectations across the foundation and enrichment curriculum, all instruction delivered in English must be linguistically accommodated (communicated, sequenced, and scaffolded) commensurate with the student's level of English language proficiency. For Kindergarten and Grade 1, certain of these student expectations apply to text read aloud for students not yet at the stage of decoding written text. The student is expected to:
ELPS.c.4A learn relationships between sounds and letters of the English language and decode (sound out) words using a combination of skills such as recognizing sound-letter relationships and identifying cognates, affixes, roots, and base words
ELPS.c.4B recognize directionality of English reading such as left to right and top to bottom
ELPS.c.4C develop basic sight vocabulary, derive meaning of environmental print, and comprehend English vocabulary and language structures used routinely in written classroom materials
ELPS.c.4D use prereading supports such as graphic organizers, illustrations, and pretaught topic-related vocabulary and other prereading activities to enhance comprehension of written text
ELPS.c.4E read linguistically accommodated content area material with a decreasing need for linguistic accommodations as more English is learned
ELPS.c.4F use visual and contextual support and support from peers and teachers to read grade-appropriate content area text, enhance and confirm understanding, and develop vocabulary, grasp of language structures, and background knowledge needed to comprehend increasingly challenging language
ELPS.c.4G demonstrate comprehension of increasingly complex English by participating in shared reading, retelling or summarizing material, responding to questions, and taking notes commensurate with content area and grade level needs
ELPS.c.4H read silently with increasing ease and comprehension for longer periods

ELPS.c.4J demonstrate English comprehension and expand reading skills by employing inferential skills such as predicting, making connections between ideas, drawing inferences and conclusions from text and graphic sources, and finding supporting text evidence commensurate with content area needs
ELPS.c.4K demonstrate English comprehension and expand reading skills by employing analytical skills such as evaluating written information and performing critical analyses commensurate with content area and grade-level needs.
ELPS.c.5 The ELL writes in a variety of forms with increasing accuracy to effectively address a specific purpose and audience in all content areas. ELLs may be at the beginning, intermediate, advanced, or advanced high stage of English language acquisition in writing. In order for the ELL to meet grade-level learning expectations across foundation and enrichment curriculum, all instruction delivered in English must be linguistically accommodated (communicated, sequenced, and scaffolded) commensurate with the student's level of English language proficiency. For Kindergarten and Grade 1, certain of these student expectations do not apply until the student has reached the stage of generating original written text using a standard writing system. The student is expected to:
ELPS.c.5A learn relationships between sounds and letters of the English language to represent sounds when writing in English
ELPS.c.5B write using newly acquired basic vocabulary and content-based grade-level vocabulary
ELPS.c.5C spell familiar English words with increasing accuracy, and employ English spelling patterns and rules with increasing accuracy as more English is acquired
