Grade 2
Tips for Helping at Home
•
Questions to ask:
What is it that you don’t understand (have
the student be specific)?
What information do you need?
What strategies are you going to use?
Can you guess and check?
Does this make sense?
What can you do to explain your answer to
show others what you are thinking?
Does your answer seem reasonable?
•
Your child will bring home two card games, Tens Go
Fish and Turn Over 10. Have your child teach the fam-
ily members how to play the games. Playing the
games frequently will help your child learn addition
combinations of 10. Please help your child find a safe
place to store these materials and directions since
some of them will be used repeatedly throughout the
unit.
•
As your child works on problems at home, encourage
him or her to record strategies for solving problems or
keeping track in ways that will make sense to your
child. Some children will use numbers, some will use
pictures or charts, others will use words, and many will
use a combination of these methods.
•
Often children will work out number problems by using
real objects. If you can, provide objects for counting,
such as beans, pennies, or buttons.

Introduction
About the Mathematics In This Unit
The emphasis of this unit is counting and sort-
ing. Your child will investigate everyday uses of
numbers, count groups of objects in more than
one way, and compare amounts. Students will
play games involving money and finding differ-
ent coins that show the same amount. They will
explore, sort, compare and describe different
shapes. The class also will collect and organize
data about themselves as a group.
Throughout this unit, your child will be using ma-
terials like interlocking cubes, pattern blocks,
Geo-blocks, and money. Students will be work-
ing with peers, writing and drawing about their
work, and talking about how they do the prob-
lems. Each of these processes is an important
emphasis in our mathematics program this year.
In addition, your child will have a math folder for
keeping track of the work he or she does in
class.

Game
Turn Over 10
Materials: One deck of Numeral Cards 0-10 (four of
each) plus four wild cards
Players: 2 to 3
How to play: The object of the game is to turn over
and collect combinations of cards that total 10.
1. Arrange the cards face down in four rows of five
cards. Place the rest of the deck face down in a
pile.
2. Take turns. On a turn, turn over one card then
another. A wild card can be made into any num-
ber.
If the total is less than 10, turn over another card.
If the total is more than 10, your turn is over and the
cards are turned face down in the same place.
If the total is 10, take the cards and replace them
with cards from the deck. You get another turn.
3. Place each of your card combinations of 10 in
separate piles so they don’t get mixed up.
4. The game is over when no more 10’s can be
made.
5. At the end of the game, make a list of the num-
ber combinations for 10 that you made.
