Picture Problems:
Understanding "How Many in All?"
The picture on the screen
shows 3 big hamburgers and 2 little hamburgers. The question I want you to answer is  How Many in All?
But before you tell me the
answer I want you to look at the number sentence
below the hamburgers and tell me what operation sign (plus or minus)
to put into the box to answer this problem correctly. So, what
operation symbol goes in the box?
Here, we want to see if your student immediately knows to add
when hearing the phrase
"how many in all"
as well as understanding of operation symbols in a number sentence.
If there is hesitation regarding whether to add or subtract you should print
and practice this skill.Remember, along with understanding the words "how many in all,"
we want to determine if your student also understands the operation symbol
for addition (as being a plus sign) and then being able to come to an
answer from looking at the number sentence. If any one of these are
wrong,
please practice this skill.
