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 problemsuse fact families to help find an unknown numberknow all your multiplication facts by memorysolve 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 divisionidentify and reason the distributive, associative, commutative and identity properties of addition and multiplication
In place value I can...use place value to round whole numbers to the nearest 10 or 100fluently add and subtract numbers in the 1,000 using different methodsmultiply one digit numbers by 10s (3 x 100, 40 x 40, 40 x 1000)understand that a fraction is a partition made from equal parts of a wholeunderstand and show how a fraction is represented on a number lineunderstand and show equivalent fractions and compare themunderstand that two fractions are equal if they are the same sizeexplain how fractions are equal using pictures or modelsunderstand that whole numbers can also be shown as fractions (5/5 equals 1 whole)compare fractions with the same numerator and denominator (<, >, =)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 datasolve 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 inchmake a line plot graph that is scaled to the nearest quarter or half inchunderstand area as the measurement of the space inside of a plane shapemeasure area in square units (cm, m, inch and feet) measure the area of a plane shape by counting the units inside a plane areaunderstand 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 relatesolve real world perimeter word problems of polygonsunderstand 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
