Sample Response:
In question 1, Kai found the LCM instead of the GCF. The
GCF of 4 and 6 is 2, not 12.
In question 2, Kai found the GCF correctly. When he used
the Distributive Property, he forgot to factor out the GCF
from 35. The correct answer should be 5(4 + 7).
2. No, No, Yes, Yes

B
Sample Response:
When Luke set up his long division problem he switched the
divisor and dividend. He should have put the 264 (the dividend) inside the division bar
and the 99 (the divisor) outside the division bar.
The correct answer after reducing the remainder is 2 .

Sample Response:
Monday: -5°F
Tuesday: -2°F
The meteorologist stated that it is going to be “below 0°F.” Numbers that are below
zero are negative, so both temperatures have to be negative. Tuesday is going to be “slightly warmer” than Monday, so Tuesday’s temperature has to
be a temperature that is closer to 0°F compared to Monday’s temperature.
Larger numbers are to the right of smaller numbers on the number line so -2°F is greater
than -5°F (it is also located closer to 0°F on a number line). Notes for Teachers
Standard 6.NS.7b requires students to explain statements of order for rational
numbers in real world contexts. This question requires students to associate a real
world description of two numbers described in words in relation to each other and zero
into numbers and justify.

To create a number line appropriately, you need to create a scale. Remember to include
0 as a number when you are making your scale. Then, place pairs of opposites correctly
around “0” on the number line using your scale.
The possible scales you can use based on the numbers in the box are to count by ones,
twos, fours or fives.
