It’s a
RIDDLE!
Volume of a
Right Triangular
Prism
CCSS.7.G.B.6
Notes to the Teacher…
After having tested these puzzles on the students in my
classroom I have noticed a few things that might help you to
experience smooth sailing with this activity…Let me share…
1.
2.
3.
4.
Be sure to go over the directions several times with
students…I find they jump right in assuming they know
what to do, and then end up at my desk asking questions.
Point out that they are to ROUND the answers they get to
the nearest whole number…they seem to look over this
detail…
The section up at the top right is the space to write the
formula for the problems on this page. I find that if the
students look up the formula, check it to be sure that it is
the correct formula, and then continually refer to the
formula while working, they stand a much better chance
of learning the process in a way that will stick in their
heads…just an idea…
And lastly, the numbers in the riddle are sideways…but
you don’t have to write the letters sideways…. : )
Riddle me this…
Can you solve this puzzle by answering the question at the
bottom of the page? Find the VOLUME OF A RRIGHT
TRIANGULAR PRISM given the length and width of the base
and height of the prism. Write your answer in the box to the
right of the problem. In the riddle below, look for any boxes
that have that number, and put the letter to the right of the
problem in the box above the number. The first one is done
for you. When you work all the problems, you will have
solved the riddle… Round answers to whole numbers. Show
all your work on a separate sheet of paper. HAVE FUN!
