Tag: Addition/Subtraction

If you don’t have a printer, see if you can try to do some on a blank piece of paper! Don’t worry about doing all of them as I know it is a lot to copy by hand! Even if you have a printer, you do not have to do all of them, I know it can be a lot! If you need a reminder of how to do double digit addition/subtraction, watch the videos in the math post from two weeks ago.

Grade 1’s Math: Triple digit addition/subtraction is aimed towards the Grade 2’s, however the Grade 1’s are more than welcome to try these! If you aren’t ready for triple digit addition/ subtraction, here are some double digit worksheets (they might be hard, but the more you practice, the better you get at doing them!). You don’t have to do all of the questions all at one time, you can work on them over the next few days or the week. If you can’t do them all, don’t worry!

Double Digit Addition:Subtraction

Grade 2’s: We have reviewed double digit addition and subtraction and now let’s practice with more digits! Adding/subtracting with three digits is the same as doing it with two digits.

1. Start with the numbers on the right (this is the ones column) then add/subtract
2. Go to the next column of numbers (this is the tens column) then add/subtract
3. Go to the first column of numbers (this is the hundreds column) then add/subtract

Here are some videos to help you:

Below are worksheets to get you started, they have the lines traced around the columns to help guide you. The two boxes at the top are for when you have to “carry the one”.

Here are some worksheets to complete! If you don’t have a printer, see if you can copy some down on a blank sheet of paper (don’t worry if you can’t do all of them). If you finish all of these, see if there are any that you didn’t complete from last week!

To extend: see if you can do some of the double digit addition/subtraction that the Grade 2’s are working on!

Grade 2’s: 

Double digit Addition

Double Digit Addition No Regrouping

Mixed Two Digit Addition:Subtraction

Addition/Subtraction: I have attached some worksheets along with some reminders for the grade 2’s about “borrowing” and “carrying the one”. There are a handful of worksheets. I do not expect these to be done all in one day or in one sitting. They can be completed over the next few days and if you don’t have access to a printer, try practicing some on a blank piece of paper.

Grade 1’s: Remember to draw dots, circles, lines or use pencil crayons or objects around you to help you if you need it! Practice counting on with your fingers too! (22+5, Put up 5 fingers, now count from 22:  23, 24, 25, 26, 27. 22+5=27). You can also use a number line to help you.

If your child has mastered single digit addition and subtraction and feels comfortable with it, the extension is for them to try the grade 2 worksheets (they may need some reminders about how to do the operations, we have practiced them in class but we have been off from school for a while!).

Here is a worksheet to get them started again with double digit addition: Double Digit Addition Traceable Boxes
