By the time they are finished the second grade, children should be able to:
Place Value / Basic Operations
- understand place value for 3-digit numbers
- count up to 1000 – counting by fives, tens and hundreds
- read and write numbers up to 1000
- compare two 3-digit numbers using greater than (>), less than (<) or equals (=)
- add and subtract numbers within 100 using various strategies
- explain which addition and subtraction strategies work
- add or subtract numbers within 1000 using concrete models
- use mental math to add or subtract 10 or 100 from any given number between 100 – 900
Fractions
- separate circles and rectangles into two, three or four equal parts and name them
- recognize that equal parts of identical wholes do not need to have the same shape
Algebraic Thinking
- solve one-step or two-step addition and subtraction word problems
- describe the strategy used to solve a word problem
- add or subtract using fact families
- work out equal groups of objects concretely (foundational learning for multiplication)
Measurement
- estimate and measure lengths in standard units
- relate addition and subtraction to length and the number line
- tell time to the nearest five minutes; write out time to the nearest five minutes
- identify money (coins and bills)
- solve a number sentence or word problem using money
- recognize that comparisons are valid only when referring to the same standard unit
- separate a rectangle into rows and columns using square units to find a total
Data Analysis
- draw a bar or picture graph and answers questions related to it
- generate data by measuring length to the nearest whole unit
- show length measurements on a line plot with whole number units
- represent whole numbers of a number line
Geometry (Shapes) / Spatial Sense
- recognize and draw shapes using specific attributes (both defining and non-defining)
- construct an array using squares that line up in rows and columns
