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 added to the foundational concepts of the next grade. 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 Dan Meyer Video Math Class needs a makeover. http://www.ted.com/talks/dan_meyer_math_curriculu m_makeover.html An example of Common Core problem-solving: Try this problem out: 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.)

Let them help you calculate tips at restaurants. 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. Let them help you calculate area, volume, surface area when completing projects around the house. Mathematics Resources at HMS If your child needs extra help, there are teachers at each grade level who offer after-school tutoring. Please take advantage of teachers’ websites for staying current on assignments, classroom newsletters, etc.
