See what we're learning.
Talk and share with your child about the day.
Review and give extra help and practice if needed.

Today in First Grade

I usually demonstrate one subtraction problem during our morning routine, but this morning I did three. They were: how many days until Thanksgiving, how much is two quarters, and how many days are left of school.


We did some practice work papers about words that use one consonant and two consonants after a short vowel.

Reading Groups:

Reading Group A:     Riding My Bike

Reading Group B:     Signs      Animals and their Babies

Reading Group C:     Alphabet Party          My Brother's Birthday


I demonstrated how to find the difference by finding what two numbers add together to make the original number.   So if you are solving 10 - 3, then you think---"What adds to 3 to make10?"  If we know our addition facts, then we know it is 7, 7 + 3 = 10.

I tried to show how all the ways to make a number are the same ways we subtract from the number, except that we turn the numbers around.   When adding, we put two numbers together to make a larger number.  When subtracting, we start with the larger number and take the smaller ones away.  

From each addition sentence, we can make two related subtraction sentences by changing the numbers' places.
