Elementary Mathematics

Distributing a given quantity among a specified number of partitions and determining the size of each partition

using a given quantity to create partitions of a specified size and determining the number of partitions formed

Part-whole: two thirds of the class went on a field trip Measure: for 5/8 use five 1/8 unit fractions to count or measureDivision: sharing $10 with 4 people is 10/4Operator: 4/5 of 20 feetRatio: the fraction 1/4 can mean the probability of an event is one in four

-Thinking of numerator and denominator as separate and not as a single value-Not recognizing equal parts-Thinking that 1/5 is smaller than 1/10 because it has a smaller denominator-Using the rules from whole numbers to compute

-Region or area models-Length models-Set models

-When going to the right of the decimal point you will divide by 10 and when going the left of the decimal point you will multiply by 10-When talking about decimal places make sure to add the "ths" to the end of the normal places

Terminating Decimals- decimals that have a specific end Repeating Decimals- decimals that keep going on with a repeating pattern and never ends (do not mistaken for an irrational number/decimal)

Integers are positive numbers, negative numbers, and zero

Discrete: something you can put in a box (physical objects usually) Continuous: time or distance

Take away Missing addendComparison

Repeated addition (discrete)Repeated addition (continuous)

Measurement (repeated subtraction)- know # in each groupParition (sharing, dealing cards)- know # of groups
