You have to use the fact that
That is so terrible that the examples do not match the problems set. Can you get her a better good that matches what she is being taught in school? It irritates me so much when I hear about books like this. My daughter's book had three definitions on one page and two of the three were outright wrong.Thank you! I am confused on why the example didn’t match the actual problems too. A lot of her work is like that.
The question is asking the following. What time is it now if in 1 hr 45 min it will be 9:30. This is a subtraction problem.My 3rd graders math homework focused on time. But the questions seemed backwards too.
______ + 1hr and 45 minutes = 9:30
REALLY? I barely figured it out let alone having my son be able to do it. School these days seem to teach things weird compared to when I went.
Has your third-grader learned the concept of borrowing, in subtraction?… School these days seem to teach things weird compared to when I went.
Yes I very much would love to see an example!Has your third-grader learned the concept of borrowing, in subtraction?
We can borrow when subtracting times given in hours and minutes. When we borrow 1 from the "hours column", we add it as 60 to the amount in the "minutes column".
Let us know, if you'd like to see an example of borrowing in standard subtraction and in time subtraction.
Sure, Ericka, but I still don't know whether your student understands the concept of borrowing (also called regrouping) in subtraction. Let's start with that. Here are two links. The written lesson has some nifty animations (plus worksheets), and the video lesson does a good job of showing place-value (by also writing the numbers expanded).… would love to see an example!
