### Curriculum Night - Henderson County Public Schools

```Curriculum Night
Mathematics
Tyler Honeycutt and Brian Frees
How is this curriculum different?
While many of the same concepts will be taught from the
NC Standard course of study, the level of thinking has
changed dramatically!
The Common Core for Mathematics has three major
components:
 Focus
 Coherence
 Rigor
Focus
 The former curriculum was often branded as being “a
mile wide and an inch deep”.
 By teaching a shortened list of “power-concepts” at
each grade level, teachers can deepen the level of
mathematical thinking on any given concept.
 The ultimate result: More connections can be made to
real-world problem solving.
Coherence
 The creators of the new curriculum set out to make sure
that the concepts taught at one grade level significantly
 The Common Core is now more appropriately aligned to
other content areas (science, social studies, etc) to
support student thinking in these classes.
Rigor
 Students are asked to think in multiple ways by:
 Explaining their solution process in depth using multiple
strategies
 Working on long-term projects that require multiple layers of
problem-solving

Centerpieces
• Erin is planning on creating a water-based centerpiece for each of the
30 tables at her wedding reception. She has already purchased a
cylindrical vase for each table. The radius of each vase is 6cm and the
height is 28 cm. She intends to fill them half way with water and then
add a variety of colored marbles until the waterline is approximately
three-quarters of the way up the cylinder. She can buy bags of 100
marbles in 2 different sizes, with radii of 9mm or 12mm. A bag of
9mm marbles costs \$3 and a bag of 12mm marbles costs \$4. (Note:
1cm3=1mL)
– A) If Erin only bought 9mm marbles, how much would she spend
on marbles for the whole reception?
– B) What if Erin only bought 12mm marbles?
– C) What if Erin wanted a mixture of marbles? Give two ways that
she could budget this with an explanation (use at least one
paragraph.)

What can I do to help my child at
home?
 Help them see “word problems” in everyday situations.
 Show them how to calculate and plan for the phone bill,
electric bill, etc.
 Use charts and diagrams from the paper or your business to
help show connections to statistics.
