Week of January 10th, 2022 
Subtraction Work (see package which can be picked up at the school)
This week we were starting subtraction with decomposition (tens and ones) 
Ex. 85 - 23
Tens 80-20 = 60
Ones 5-3 = 2
60+2 =62
We are also looking at stacked subtraction 85
                                                                         -23
                                                                  ________
                                                                           62
I am planning on teaching about regrouping/borrowing with subtraction at the end of the week, so students get a proper lesson on this! If parent's are feeling keen and want to move ahead with this, by all means do!



2 and 3 Digit ADDITION no regrouping
2 and 3 Digit Subtractio NO borrowing

Here are some fun math card games!

These are not complex subtraction or addition skills, but aim to help increase fluency and speed with subtraction (some adding).
