-Play “War” with a
standard deck of
cards. Shuffle and
deal face down.
Reds are negative,
blacks are positive.
Sounds like:
“7,563, 330 falls between
7, 560,000 and
7, 570,000.”
“The halfway point is
7,565,000.”
“It is closer to 7,560,000.”
“It is -4 degrees, and warms
up 10 degrees. It is now 6
degrees.”
(Keep on Math Wall)
Track daily temp, table
points, etc.
I have 6 dollars but owe my
brother 10. After I give him
6, I’ll still owe 4 dollars
more.

twenty is eighty. Twenty
groups of four is also
eighty. Finally, 20 groups
of 20 is 400. When I add

“25 cents is 25 hundredths
of a dollar.”
“I must line up the
decimals so that I can add
tenths to tenths and
hundredths to
hundredths.”

-Distribute various number
from 1-100 and ask if it is
divisible by 2,5,10
-Use calendar to determine
which dates are divisible by
2,5,10
“I know that 2/4 and ½ are
equivalent fractions
because they describe the
same part.”
Reinforce by using
a ruler to create
