Math
We learn many different aspects of math in second grade. We study numbers to 999, focus on number sense, place value, 2 and 3 digit addition and subtraction with regrouping, geometry, money, fractions, equal (“fair”) shares, time, measurement and end the year with multiplication and division.
A Sea Otter may ask (these are straightforward, try larger 2 and 3 digit numbers too):
(Beginning number unknown)
“I ate lots of shellfish today. I ate 7 mussels and have 8 empty clam shells on my tummy. How many total shellfish did I start out with to eat today?” (__ - 7 = 8)
(Middle number unknown)
“I found 15 shellfish this morning. I have 8 clams left. How many mussels did I eat today?” (15 - __ = 8)
(End number unknown)
“I carefully balanced 8 clams and 7 mussels on my tummy before eating. I was hungry and ate them all! How many did I eat?” (8 + 7 = __)
