This Week's Work : Week 47 - for Inquisitive Young Mathletes

This week, we'll continue discussing this year's Mathcounts state harder problems. Please try these problems before our lesson. Review sprint round questions we went over at last Sunday's lesson, especially #18 to see if you can get that question right and fast the first try. The technique used for this question is very similar to the first explanation from this episode of Mathcounts mini -- more construction counting. Review Binomial Theorem and see if you can use the following concepts solving this year's state sprint # 28. (You can also use modular arithmetic, or mod.) Chapter 14: The Binomial Theorem

• Section 14.2: Introducing the Binomial Theorem   
• Section 14.4: Using the Binomial Theorem Part 1
• Section 14.4: Using the Binomial Theorem Part 2
• Section 14.4: Using the Binomial Theorem Part 3
• Section 14.5: Using the Binomial Theorem Part 4

Have a calculator ready for target and team round questions.

Take care and happy problem solving !!
