Pennsylvania 3rd Grade Math Standards

All 14 Pennsylvania math standards for 3rd grade, each explained in plain English. The official wording is in Pennsylvania Department of Education's document, linked at the end of this page.

14 standards

Numbers & Operations in Base Ten

1 standard
CC.2.1.3.B.1
Round whole numbers to the nearest 10 or 100, add and subtract within 1,000 fluently, and multiply one-digit numbers by multiples of 10, like 9 × 80.

Numbers & Operations—Fractions

1 standard
CC.2.1.3.C.1
See fractions as numbers, like 3/4 as three parts of size 1/4, place them on a number line, and compare fractions with the same numerator or denominator.

Operations and Algebraic Thinking

4 standards
CC.2.2.3.A.1
Solve multiplication and division word problems within 100 about equal groups, arrays, and measurements, and find unknowns like 8 × ? = 48.
CC.2.2.3.A.2
Use multiplication rules like changing the order or grouping of factors, and solve division as a missing factor, like 32 ÷ 8 by asking 8 times what is 32.
CC.2.2.3.A.3
Multiply and divide within 100 quickly and accurately, and know all products of two one-digit numbers from memory by the end of the year.
CC.2.2.3.A.4
Solve two-step word problems using all four operations, check answers by estimating, and find and explain number patterns, like why 4 times any number is even.

Geometry

2 standards
CC.2.3.3.A.1
Sort shapes by their features, like seeing that squares, rectangles, and rhombuses all belong to the larger group of quadrilaterals.
CC.2.3.3.A.2
Divide a shape into parts with the same area and name each part as a unit fraction, like each of 4 equal parts is 1/4 of the whole shape.

Measurement and Data

6 standards
CC.2.4.3.A.1
Measure and estimate temperature, liquid volume, mass, and length, and solve word problems with these measurements, like adding grams or liters.
CC.2.4.3.A.2
Read clocks and write the time to the nearest minute, and solve word problems about elapsed time, like how long it is from 9:15 to 9:50.
CC.2.4.3.A.3
Solve money word problems using combinations of coins and bills, including working out how much change to give back.
CC.2.4.3.A.4
Show data in bar graphs, pictographs, line plots, tally charts, and tables, including graphs with scaled units, and answer questions from them.
CC.2.4.3.A.5
Find the area of a rectangle by counting unit squares or multiplying its side lengths, and split a figure into rectangles to add their areas.
CC.2.4.3.A.6
Solve problems about the perimeter of polygons, including finding a missing side, and tell the difference between measuring around a shape and covering it.
