Look and Say Sequence Game: Code Theory

In mathematics, the look-and-say sequence is the sequence of integers

Scrabble Algebraic Method, Ascending and Most Frequent Value

Last week, I introduced how mathematicians use algebraic symbols to represent numbers. We used the ascending value method where A=1, B=2, C=3 …. Z=26. One way to connect language and math is to have children convert words to numbers using several different letter valuation methods. The children were asked to add the value of each letter.

CREATE ALGEBRAIC EQUATIONS: Ascending Value of the Alphabet

Algebraic expressions are letters that we assign to unknown values or to specific values. 


Combinatorics: How many 3-digit numbers have digits which have a sum of:

An 11th grade SAT questions asked students to find the number of 3-digit numbers that have a sum of 6. On this ubiquitous test that gains most students entrance to college, you only have a little over a minute to answer the question.
