 * Important Skills || Misconceptions ||
 * * Composing/Decomposing numbers- especially tens and ones
 * Thinking of subtraction as finding the difference between two numbers
 * Understanding that word problems can be modeled with drawings- shortcuts are not beneficial to foundational learning!
 * Adding and subtracting 10 to/from any number
 * Estimating answers and “thinking” mathematically- not depending upon rote procedures for operation
 * Doubles should be memorized
 * Place Value
 * Number Sense- quantity of numbers
 * Addition and subtraction strategies should focus on how facts relate to other facts, NOT counting up and counting back
 * Mental Math should be emphasized
 * Basic Facts to 10– strategies
 * Benchmark of 5 and 10
 * One more/one less
 * Comparing numbers
 * Unitizing
 * Experience with a variety of problems
 * 1 to 1 correspondence
 * Count to 100- ones and tens
 * Number order (understand the number before and the number after)
 * Greater than/less than
 * Add and subtract with ease to 20 (should have mental strategies to use for this)
 * Understand fact families
 * Time to hour
 * Basic shapes and properties
 * Write numbers to 100
 * When adding or subtracting 2-digit numbers, I must line up the numbers and begin in the ones column
 * Subtract means “take away” or “count backwards”
 * When solving word problems, I just need to find the two numbers and then look for clue words. Then I add or subtract
 * For all simple addition problems, I just put the big number in my head and count up the other numbers on my finger.
 * “line down the middle as a strategy”
 * Bigger number on top in subtraction
 * Which clock hand to read first
 * Value of nickel and quarter
 * The place of the number determines it value (thinking that the 9 in 91 only represents 9 instead of 90) || * When adding or subtracting 2-digit numbers, I must line up the numbers and begin in the ones column
