Have you seen my Alphabet Coloring site? Over the last several years, since first releasing the Plants and Animals Uppercase printable coloring pages, I have been asked many, many times for the names of all the plants and animals in each letter. I am thrilled to finally have a definitive answer key for these! Yay! Just go to the alphabet page itself, and you’ll see a link to the answer key.
See ya on the Net,

#2. Sequences and Series
by Barbara J. Feldman
Sequences and Series Printable (** for premium members only)
This week’s topic is one usually studied in first year algebra: sequences and series. Let’s start with some definitions. A sequence is an ordered list of numbers, and a series is the sum of the terms (the individual numbers) of a sequence. For more lessons, here are my weekly website picks.
Cool Math Algebra: Sequences & Series Lessons
“A sequence is a list of numbers (or other things) that changes according to some sort of pattern.” This ten lesson section introduces arithmetic sequences, series, sigma notation, geometric sequences, mathematical induction and the binomial theorem. To move from one lesson to the next (each lesson is multiple pages), you need to return to this menu, which is linked at the bottom of each page.
Math is Fun: Arithmetic Sequences – Finding a Rule
“To find a missing number, first find a Rule behind the Sequence. Sometimes you can just look at the numbers and see a pattern.” After a few examples of how trial and error can help you discover a rule, at the bottom of the page you’ll find links to related topics, including Arithmetic Sequences, Geometric Sequences, Fibonacci Sequence and Triangular Sequence. Each of these topics also include related links at the bottom of the page, so be sure to look for them.
Math Guide: Arithmetic Sequences
After defining arithmetic sequences, this Math Guide lesson explains how to calculate the nth term. “In order for us to know how to obtain terms that are far down these lists of numbers, we need to develop a formula that can be used to calculate these terms. If we were to try and find the 20th term, or worse to 2000th term, it would take a long time if we were to simply add a number — one at a time — to find our terms.” At the bottom of the page, you’ll find four interactive quizzes on sequences and series.

#6. Quote of the Week
“To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature … If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in.” ~~ Richard Feynman ~~ (May 11, 1918 – February 15, 1988) American physicist, author, professor, and prankster.
