Just a reminder...
Our pizza party is on Monday. Please send in $2.00 TOMORROW if you would like your child to have pizza for lunch on Monday!
Field day is in 1 more week!!! Mr. C and Mrs. O’Shea have requested that first graders wear green shirts on that day. If you would like to purchase a green shirt (plain) please fill out the attached form and send in $4.00 (cash only) in an envelope with your child’s name on it by MONDAY (6/4). If you already have a green shirt at home, please have your child wear it next Friday (6/8).
We are also planning on letting the children sign each other’s shirts with a sharpie. Please let us know, by signing the attached form, if you give permission for your child to have his/her shirt signed.
More information on field day will come home next week. We are looking forward to a fun filled day!!!
If you have any questions, let us know.

We are finishing up Chapter 14: Mental Math Strategies today and our test will be TOMORROW! 157: Spanish 158: English
In this chapter we learned:
how to add ones mentally by using a doubles fact. Ex: 7+6=____ 6+6=12; 12+1= 13 so, 7+6=13
how to add mentally by using the 'add the ones' strategy.
Ex: 23+4=___ 23 becomes 20 and 3. Add the ones: 3+4= 7. Add the ones to the tens: 20+7= 27
how to add mentally by using the 'add the tens' strategy.
Ex: 15+20=____ 15 becomes 10 and 5. Add the tens: 10+20= 30. Add the tens to the ones: 5+30= 35
how to subtract ones mentally by recalling number bonds (think of addition). Ex: 8-5=_____ 8= 5+ ____ 8=5+3 so, 8-5= 3
how to subtract mentally by using 'subtract the ones' strategy.
Ex: 37-4=________ 37 becomes 30 and 7. Subtract the ones: 7-4= 3. Add the ones to the tens: 30+3= 33. So, 37-4= 33
how to subtract mentally by using 'subtract the tens' strategy.
Ex: 35-20= ______ 35 becomes 30 and 5. Subtact the tens: 30-20= 10. Add the tens to the ones: 10+5= 15. So, 35-20= 15
word problems using addition or subtraction: I have 16 fish. 9 of them swam away. How many fish are left?
It is important to keep in mind that your child was introduced to each of these strategies, but we encourage each student to use the strategy that works for them. They are not required to use all of these strategies, just one!
Our next chapter is 16: Numbers to 100
