Unique Number Sentences
Most word problems should be solved by writing a basic number sentences with the
answer being the number to the right of the equal sign. Although,
this problem could be solved by finding the difference between the two
numbers, it really should be a two step problem. The first step
should be to make a number sentence that goes with the word problem (10
- ? = 6),
the next step would be to get a number line (or draw 10 objects) and cross
them out until 6 are left.
These types of problems are certainly more
difficult than if we said - Lucy had 10 cards. She gave away 4, how
many are left? This simpler problem type is in the next skill 4G.
Lucy has 10 baseball cards.
She gives some to her friend
and now has 6 cards left.
How many baseball cards did she give to her friend?
