CCR Standard(s) for Mathematical Practice:
MP.7 Look for and make use of structure.
Understanding (s)
Students will understand…
That data can be organized into visual
representations that make them easier to
compare
Essential Question(s)
Why are graphs a useful tool in
math?
That multiplication and division are
reverse operations, as are addition and
subtraction (limited to whole number
explorations)
There are different strategies that can
be used to arrive at an answer
Student Knowledge and Skills
Students will know …
How to round to useful amounts to make the problem more accessible
How to count by 10s and relate that to multiplication
Students will be able to …
Use the relationship between addition and subtraction to answer questions
1
about data
Make statements about data using multiplication and division
Organize data in a systematic manner
Performance Task(s):
Stage 2 – Assessment Evidence
Other Evidence:
Students will present a report on the
results of their review of at least
two different childcare situations.
Hi-SET-like questions
Mental math activities involving
multiples of 10
Practice word problems involving
the four operations with whole
numbers
Stage 3 – Learning Plan
Learning Activities [some sample lessons without detail or specific
organization – this is not an exhaustive list of lessons to be used in this unit]
Classroom discussion on childcare issues, including criteria that students
think are important in making decisions about childcare
Exploring multiples of 10 and comparing those multiples to addition,
multiplication, and division
Collect survey data with two categories and plot of a frequency graph; also
collect data over time about attendance and continue to build a pictograph
of the results.
Compare bar heights to make general statements about data
