**Jackie Murawska**, Ed.D., of North Central College - Naperville, Illinois gave a presentation at the Illinois Council of Teachers of Mathematics Annual Meeting October 18, 2013 and I’ve shared some of her slide content below. The link to her entire presentation is below; take a look – she has some nice stuff!

**Why Is KenKen Good?**

Fun! I mean – engaging; Builds confidence; Encourages positive attitudes; Aligns with Common Core Standards for Mathematical Practice K-12 Content

Here are the **Standards for Mathematical Practice** for reference:

Mathematically proficient students:

1. Make sense of problems and persevere in solving them

2. Reason abstractly and quantitatively

3. Construct viable arguments and critique the reasoning of others

4. Model with mathematics

5. Use appropriate tools strategically

6. Attend to precision

7. Look for and make sure of structure

8. Look for express regularity in repeated reasoning

**KenKen Promotes…**

Problem solving and perseverance

MP. 1 Make sense of problems and persevere in solving them

Reasoning

MP. 2 Reason abstractly and quantitatively

Communication and teamwork

MP. 3 Construct viable arguments and critique the reasoning of others

Argumentation and justification

MP. 3 Construct viable arguments and critique the reasoning of others

**KenKen Helps Build Skills Required for Common Core Mathematics K-12…**

Basic math facts

2.OA.2 Fluently add and subtract within 20 using mental strategies.

3.0A.7 Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division

Number theory topics: divisibility, factors, primes

4.OA.4 Find all factor pairs for a whole number in the range 1–100…Determine whether a given whole number in the range 1–100 is prime or composite.

Combinatorics

K.OA.3 Decompose numbers less than or equal to 10 into pairs in more than one way

HS.F-IF.7c Graph polynomial functions, identifying zeros when suitable factorizations are available, and showing end behavior.

HS.S-CP.9 Use permutations and combinations to compute probabilities of compound events and solve problems
