• NYS Third Grade Math Standards

    What will I be able to do as a third grade mathematician?
    In operations and algebraic thinking I can ...
        -understand multiplication as repeated addition and see objects in groups or sets (5x7 is 5 groups of 7 objects each)
       - understand division is repeated subtraction and see objects are shared into equal groups (35 divide by 7 equally means 7 people each get 5 parts)
       -use multiplication and division to solve word problems
       -draw arrays, equal groups and pictures in multiplication and division word problems
       -use fact families to help find an unknown number
       -know all your multiplication facts by memory
       -solve two step word problems using the four operations (addition, subtraction, multiplication and division)
       -identify patterns in numbers and explain them using addition, subtraction, multiplication and division
       -identify and reason the distributive, associative, commutative and identity properties of addition and multiplication
    place value
    In place value I can...
        -use place value to round whole numbers to the nearest 10 or 100
       -fluently add and subtract numbers in the 1,000 using different methods
       -multiply one digit numbers by 10s (3 x 100, 40 x 40, 40 x 1000)
    In fractions I can...
        -understand that a fraction is a partition made from equal parts of a whole
       -understand and show how a fraction is represented on a number line
       -understand and show equivalent fractions and compare them
       -understand that two fractions are equal if they are the same size
       -explain how fractions are equal using pictures or models
       -understand that whole numbers can also be shown as fractions (5/5 equals 1 whole)
       -compare fractions with the same numerator and denominator (<, >, =)
    In measurement and data I can...
        -tell and write time to the nearest minute and measure time intervals in minutes
       - solve word problems that use addition and subtraction of minutes
       - measure and estimate liquid volume and masses using g, kg, and l
       - add, subtract, multiply or divide to solve one step problems that use mass or volume
       - draw a scaled bar graph or pictograph to show data
       -solve one step word problems about graphed data (how many more... how many less)
       - measure using a ruler to the nearest inch, half inch and quarter inch
       -make a line plot graph that is scaled to the nearest quarter or half inch
       -understand area as the measurement of the space inside of a plane shape  
       -measure area in square units (cm, m, inch and  feet)
       - measure the area of a plane shape by counting the units inside a plane area
       -understand that area relates to addition and multiplication
       - find the area of a rectangle using shapes to cover and then making a multiplication sentence to show how they relate
       -solve real world perimeter word problems of polygons
    In geometry I can...
       -understand that shapes can share attributes (square, rectangle and parallelogram are all quadrilaterals)
       -draw various quadrilaterals (square, rhombus, rectangles)
       -partition shapes into equal parts and areas. 
       -understand the area of each part is really a fraction of the whole
