Tomorrow is the math test. It looks exactly like the homework that has been coming home. Tonight they have 2 pages to serve as their study guide. They will be asked to do 3 digit addition problems using one or more of the methods that we have been learning: the arrow way, the number bond way, vertical form (traditional),or place value chart and chips. Some questions will ask what is the most effective method (best way) to solve a problem.
Arrow way is most effective when one of the numbers end in a zero, because then you just have add hundreds or tens.
Number bond is most effective when one addend is close to a hundred mark, or a 10 and you can make a friendly number. Examples would be 198 +54, 97 + 365, 511 + 399. All of these problems have an addend close to a hundred mark.
Vertical form and place value chart and chips work best for numbers that can’t easily be broken into friendly numbers, or mostly hops of 10 or 100.
Please see the pictures for examples of each of these.
