Math Facts

We are starting a new math unit on addition and subtraction. In this unit we learn how to apply addition and subtraction and we learn strategies for the basic addition and subtraction facts. We  slowly work our way through a list of strategies, practising each strategy as we go. Today we already practised +1 and +2. I call the +2's "head bobbers" because we just start with the big number and then bob our head and count two more. Pretty soon the kids will not need to count out loud while bobbing and will be able to answer automatically. Today we took out our playing cards from 1-9 and just drew random cards and practiced adding 1 and then 2. Don't forget to say 2 plus ____, as well as ____  + 2. In other words have the blank both before and after the + 2.  



These are the facts that should be practiced this week:

1+1, 1+2, 1+3, 1+4, 1+5, 1+6, 1+7, 1+8, 1+9, and same in the other order  2+1, 3+1, 4+1 etc.

2+2, 2+3, 2+4, 2+5, 2+6, 2+7, 2+8, 2+9, and the same in the other order  3+2, 4+2,5+2, 6+2, etc. These facts should be known automatically.



Having said all this, we do have kids in our class who already know all of their facts to ten automatically already. Great!
