Hello Families!
We began Unit 3: Addition and Subtraction Story Problems today. I gave students a pre-test and will place them in math groups accordingly. These groups are flexible and as I see quick quizzes and in-class work, I will certainly adjust them. I wanted to give you a little heads up on some lingo that will be used in the homework.
(+)Change Plus Problem: A problem that begins with a given quantity that is then changed by adding more to it.
Example: Al has 4 toy cars. His mom bought him 5 more. How many does he have now? *note, he is adding more to his original quantity
(-)Change Minus Problem: A problem that begins with a given quantity that is then changed by taking some away.
Example: Joy had 12 apples. She ate 4. How many does she have now? *note, 4 are being taken away - they are done, gone, outta here.
(+)Put Together Problem: A problem that involves putting together (joining, combining) different groups of items to form a total.
Example: Anna has 3 oranges. Joel has 4 oranges. How many do they have altogether? *note, there were two separate quantities that are being combinedinto one group - we aren't actually changing the amount of oranges that are present, just combining
(-)Take Apart Problem: A problem that involves separating a group of objects.
Example: There were 12 horses in the field. Then, 4 went in the barn. How many are left in the field?*note, the horses that are being subtracted aren't actually going away, just going somewhere separate.
When tackling story problems in this unit, encourage your child to draw a math mountain! That way, he or she can see what we know, and what we need to figure out.
Happy homeworking!!
