Explain
THE STRATEGIES USED TO SOLVE PROBLEMS INVOLVING ADDING AND SUBTRACTING WITHIN 10 USING SPOKEN WORDS, CONCRETE AND PICTORIAL MODELS, AND NUMBER SENTENCES
Including, but not limited to:
 Whole numbers
 Counting (natural) numbers – the set of positive numbers that begins at one and increases by increments of one each time {1, 2, 3, ..., n}
 Whole numbers – the set of counting (natural) numbers and zero {0, 1, 2, 3, ..., n}
 Addition
 Addend – a number being added or joined together with another number(s)
 Sum – the total when two or more addends are joined
 Addition of whole numbers with sums up to 10
 Subtraction
 Minuend – a number from which another number will be subtracted
 Subtrahend – a number to be subtracted from a minuend
 Difference – the remaining amount after the subtrahend has been subtracted from the minuend
 Subtraction of whole numbers to find differences within 10
 Including 0 as the subtrahend
 Including 0 as the difference
 Mathematical and realworld problem situations
 Detailed explanation of the solution process and strategy
 Addition strategies
 Count all
 Count on from the first number presented
 Count on from the largest number
 Subtraction strategies
 Removing
 Count backward
 Count on
 Connection between information in the problem and problem type
 Joining situations in contexts that represent an action (e.g., Kristin had 2 pencils, and her teacher gave her 3 more pencils; etc.)
 Joining situations in contexts that represent no action (e.g., Kristin had 2 blue pencils and 3 red pencils; etc.)
 Separating situations in contexts that represent an action (e.g., Mark had 5 books, and then he gave 2 books away; etc.)
 Relationship between quantities of objects used, pictures drawn and number sentences to the problem situation
 Explanation using spoken words
 Appropriate mathematical language for joining or separating situations
 Labels for quantities represented
 Explanation using objects
 Linking cubes, counters, etc.
 Explanation using pictorials
 Explanation using number sentences
 Number sentence – a mathematical statement composed of numbers, and/or an unknown(s), and/or an operator(s), and an equality or inequality symbol
 Addition symbol represents joining
 Addend + addend = sum
 Sum = addend + addend
 Subtraction symbol represents separating
 Minuend – subtrahend = difference
 Difference = minuend – subtrahend
 Equal symbol indicates the same value being represented on both side(s)

K.5 
Algebraic reasoning. The student applies mathematical process standards to identify the pattern in the number word list. The student is expected to:


K.5A 
Recite numbers up to at least 100 by ones and tens beginning with any given number.

Recite
NUMBERS UP TO AT LEAST 100 BY ONES AND TENS BEGINNING WITH ANY GIVEN NUMBER
Including, but not limited to:
 Counting numbers (1 – 100+)
 Counting (natural) numbers – the set of positive numbers that begins at one and increases by increments of one each time {1, 2, 3, ..., n}
 Number word sequence has a correct order
 Recite – to verbalize from memory
 Development of automaticity
 Relationship to counting
 Cardinal number – a number that names the quantity of objects in a set
 Hierarchical inclusion – concept of nested numbers, meaning each prior number in the counting sequence is included in the set as the set increases (e.g., 18 is 17 increased by 1; 18 decreased by 1 is 17; etc.)
 Count forward up to at least 100
 Orally by ones beginning with 1
 Orally by ones beginning with any given number
 Orally by tens beginning with 10
 Orally by tens beginning with any given number between 1 and 100
 Beginning number is a multiple of 10.

 One unit of data represented by each object or picture
 Picture graph – a graphical representation to organize data that uses pictures or symbols evenly spaced or placed in individual cells, where each picture or symbol represents one unit of data, to show the frequency (number of times) that each category occurs
 One unit of data represented by each object or picture

 Identification of title and category labels
 Explanation of what the graph represents
 Conclusions related to the question that led to the data collection
