Which number sentence completes this fact family?
3+2=5 2+3=5 5-2=3
is it 5+2=7, 5+3=8, 5-1=4 or 5-3=2?
Well, since the first three sentences all deal with just 2,3, and 5, I'd say that 5-3=2 is the logical choice. Nothing to do with 4,7, or 8.
you simply must chose whether which one makes sense so I would go with5-3=2
5-3=2
To find the missing number sentence that completes the fact family, we need to look for a number sentence that follows the same pattern as the given three equations.
In the given equations, we have:
3 + 2 = 5
2 + 3 = 5
5 - 2 = 3
From the first two equations, we can see that the order of the numbers being added does not matter: 3 + 2 is the same as 2 + 3. Therefore, for the missing number sentence, we can simply swap the numbers being added.
Since we're given two possibilities in the options: 5 + 2 = 7 and 5 + 3 = 8, we need to choose the one that follows the pattern we observed.
So, the number sentence that completes the fact family is:
5 + 2 = 7
This choice maintains the pattern observed in the given equations.
