Now, let’s put them in columns: Look at the ones – we’re trying to take 6 away from 4. That’s not possible, so we have to borrow 10 from the tens column. Now we can now take 6 away from 14. The answer is 8.

A reasonable estimate of the product is $420. True False 23b. Using partial products, the products are 42 and 180. True False 23c. Using regrouping, 18 ones are regrouped as 8 tens and 1 one.

Open number lines are the fourth strategy for 2-digit addition and subtraction problems. An open number line is where students have make jumps in order to represent adding or subtracting tens and ones. On a subtraction problem the students will begin on the biggest number. Then, they will jump back the number that they are supposed to subtract.

So it's 35 plus 2 is 37. Now, we write the 7 right over here in the tens place and carry the 3. Now we need to compute what 7 times 2 is. We know that 7 times 2 is 14 from our multiplication tables.
