This week’s PSSA item sampler

Below is an example of a 5th grade math problem students might experience while taking the PSSAs.  Good luck.

Martha makes the statement shown below:

When multiplying two whole numbers that end in zeros, the product always has
the exact same number of zeros at the end as the number of zeros from the end
of the two numbers combined.

For example, the product of 80 × 400 has exactly three zeros at the end since 80 ends in one zero and 400 ends in two zeros. Which expression proves Martha’s statement is not correct?

A. 10 x 100

B. 20 x 200

C. 30 x 400

D. 40 x 500
