Study Notes
Math for Elementary Grades
Addition Facts
 Number sense: understanding that numbers can be combined to make a total or a whole
 Basic addition: combining two or more numbers to get a total or a sum

Addition facts: basic number combinations that are memorized to solve simple addition problems quickly
 Examples: 2+2=4, 5+1=6, 8+0=8
 Number lines: a visual representation of numbers to help students understand relationships between numbers

Counting on: starting with a number and counting on to find the total
 Example: 3+2=? Start with 3, count on 2 more: 4, 5
Multiplication Tables
 Repetition and patterns: understanding that multiplication is repeated addition
 Basic multiplication: combining a number a certain number of times to get a product

Multiplication tables: memorized charts of multiplication facts for quick recall
 Examples: 2 x 3 = 6, 5 x 4 = 20
 Arrays: visual representations of objects arranged in rows and columns to represent multiplication
 Realworld applications: using multiplication to solve everyday problems (e.g., arranging blocks, seating at a table)
Basic Subtraction
 Number sense: understanding that numbers can be taken away to get a difference
 Basic subtraction: finding the difference between two numbers

Counting back: starting with a number and counting back to find the difference
 Example: 83=? Start with 8, count back 3: 7, 6, 5
 Number lines: a visual representation of numbers to help students understand relationships between numbers
 Realworld applications: using subtraction to solve everyday problems (e.g., subtracting blocks, finding the difference in height)
