CONCEPTS AND CONTENT
IN SECOND GRADE CLASSROOM
Students will be able to
demonstrate fluency with addition facts to 12.
Students will explore patterns and develop fluency in skip counting by 2’s,
5’s and 10’s to 100.
Students will be able to name and understand the value of money; penny,
nickel, dime, quarter, half-dollar and dollar
Students will use the phases of problem solving’ understand, plan, carry out
and look back.
Students will use mental computation to add single digit numbers when
written vertically and horizontally.
Students will be able to use the following addition strategies: count on,
doubles, doubles+1, double the skipped number, turn-arounds, and make ten.
Students will be able to communicate about mathematical thinking through
written and oral language.
HELP AT HOME
Parents can help their children.
- Work with your child in their
acquisition of addition facts.
- Help your child notice large and
small numbers in magazines and newspapers and practice reading the
numbers.
- Play number games: i.e. roll two or
three dice and fine their sum.
- Play a card game with your child.
Players pick a card and collect as many pennies as the number shown on the
card. Then players count each other’s pennies and figure out how many
more pennies one player has than the other.
- Use various household objects (coins,
paperclips, pencils, etc.) to create addition problems to 12. Have your
child solve the problem and communicate their thinking through oral and
written communication.
- For one day count all of the cars you
see. Record the color of each car. Create a graph and record the data.

Students will see the
relationship between addition and subtraction. They will use various
strategies including, but not limited to:
-
Counting on
-
Doubles
-
Doubles plus one
-
Double the skipped number
-
Turn arounds
-
Combinations of 10
-
Count back
-
Count up
-
Think addition
Students will use horizontal
and vertical notation for addition and subtraction.
Students will be familiar with the structure and patterns of our number
system
Students will work with 100 and combinations of numbers that equal 100
HELP AT HOME
Parents can help their children.
-
Work
with your child in their acquisition of addition and subtraction facts.
-
Ask
your child to count out a handful of pennies in two different ways. (count
by 2’s and 5’s)
-
Ask
your child to count the change in your pocket.
-
Find
items sold in sets and ask your child to determine how many there would be
in multiple sets of packages. (e.g. soda cans, yogurt, batteries, etc.)

CONCEPTS AND CONTENT
IN THE SECOND GRADE CLASSROOM
Students will be able to
demonstrate fluency with addition and subtraction facts to 20.
Students will demonstrate as understanding of relative magnitude and
position of numbers from 1 – 1000.
Students will estimate reasonable answers to problems prior to calculation.
Students will use mental computation to solve problems.
Students will subtract multidigit numbers from multidigit numbers with
and without renaming.
Students will use nonstandard units to develop an understanding of
measurement. They will use standard units to measure:
Inches, feet, yards
Centimeters, meters
Cups, pints, quarts, gallons, liters
Ounces, pounds, kilograms, grams
HELP AT HOME
Parents can help their children.
- Continue to work with your child in
their acquisition of addition and subtraction facts.
- Play number games: How many 4-digit
numerals can be made using the digits 2, 3, 5, and 7 without repeating a
digit?
- Estimate answers to addition and
subtraction problems. Then find the solution using mental computation
strategies.
- Play the number games your child
brings home from school. Keep these games and play them throughout the
year.
- Estimate and measure distances at
home.
- Include your child when using
measuring at home in sewing, building and cooking.
- Go on a Scavenger Hunt. Use
estimation skills to find objects of certain measurements.
- Measure how far you can jump from a
standing position. Do this 5 times. How long was the longest jump? How
long was the shortest jump? Measure 5 jumps for another member of your
family..
