Common core performance assessment
julia puts her stickers into arrays in
an album. some of her stickers are
animal stickers. there are a different
number of stickers on each page. the
table at the right shows information
about the stickers in julia's album
julia's stickers

stickers
columns
of stickers
4. mp.5 use appropriate tools explain
how you can use one of these tools to
find the number of stickers on each page:
a number line, counters, a hundreds chart
5. mp.1 make sense and persevere julia multiplies to
find the total number of stickers on each page. for
each page, tell the factors that she multiplies.
you can generalize by
thinking about the factors
that you use repeatedly
to solve problems
6. mp.7 use structure look at the facts you wrote for 5.
break these facts into 15, 2, 3s, and 5s facts to find the
total number of stickers on each page.
page 1
(x -1x + l x ) =
page 2
lx -1x + ( x ) =
page 3
lx -lx + lx - _
page 4
(x - 2x + ( x ) =
7. mp.8 generalize look at the 1s, 2s, 3s, and 5s facts
above. what generalizations can you make? test each
generalization with another fact.
