### Math

Unit 1: Foundations of Number Aug 28- Sept 8

• Week 1: Numerations

• Identify base 10 relationships

• compare/order numbers

• Extend understanding of thousands comma

• Place value chart

• Place value blocks

• Week 2: Numerations

• Compose/decompose numbers

• Standard, expanded, word form

• Digits are 10 times greater the digit to the right

• Unit Vocabulary:

• Compare numbers – to consider the value of two numbers to determine which number is greater or less or if the numbers are equal in value
• Compose numbers – to combine parts or smaller values to form a number
• Counting (natural) numbers – the set of positive numbers that begins at one and increases by increments of one each time {1, 2, 3, ..., n}
• Decompose numbers – to break a number into parts or smaller values
• Digit – any numeral from 0 – 9
• Expanded form – the representation of a number as a sum of place values (e.g., 56,789 as 50,000 + 6,000 + 700 + 80 + 9)
• Expanded notation – the representation of a number as a sum of place values where each term is shown as a digit(s) times its place value (e.g., 56,789 as (5 x 10,000) + (6 x 1,000) + (7 x 100) + (8 x 10) + (9 x 1))
• Numeral – a symbol used to name a number
• Open number line – an empty number line where tick marks are added to represent landmarks of numbers, often indicated with arcs above the number line (referred to as jumps) demonstrating approximate proportional distances
• Order numbers – to arrange a set of numbers based on their numerical value
• Place value– the value of a digit as determined by its location in a number such as ones, tens, hundreds, one thousands, ten thousands, etc.
• Whole numbers – the set of counting (natural) numbers and zero {0, 1, 2, 3, ..., n}
• Word form – the representation of a number using written words (e.g., 56,789 as fifty-six thousand, seven hundred eighty-nine)
