Welcome to the wonderful world of Algebra 1 Online! This course contains both content that reviews or extends concepts and skills learned in previous grades and new, more abstract concepts in algebra. Students will gain proficiency in computation with rational numbers (positive and negative fractions, positive and negative decimals, whole numbers, and integers) and algebraic properties. New concepts include solving two-step equations and inequalities, graphing linear equations, simplifying algebraic expressions with exponents, i.e. monomials and polynomials, factoring, solving systems of equations, and using matrices to organize and interpret data. Students will be actively engaged using concrete and virtual materials and appropriate technologies such as graphing calculators and computer software. Mathematics has its own language, and the acquisition of specialized vocabulary and language patterns is crucial to a student’s understanding and appreciation of the subject.

World Population: Past, Present, and Future (move and expand the bar at the bottom of the chart to navigate through time) The chart above illustrates how world population has changed throughout history. View the full tabulated data. At the dawn of agriculture, about 8000 B.C., the population of the world was approximately 5 million. Over the 8,000-year period up to 1 A.D. it grew to 200 million (some estimate 300 million or even 600, suggesting how imprecise population estimates of early historical periods can be), with a growth rate of under 0.05% per year. A tremendous change occurred with the industrial revolution: whereas it had taken all of human history until around 1800 for world population to reach one billion, the second billion was achieved in only 130 years (1930), the third billion in 30 years (1960), the fourth billion in 15 years (1974), and the fifth billion in only 13 years (1987). Wonder how big was the world's population when you were born? Growth Rate 10 Billion (2055)

As I was looking over my presentation for this week at NCTM and getting sidetracked by checking Tweets about NCSM (which I didn’t get to attend this year), I saw a few tweets about Steven Leinwand and Patsy Kanter’s presentation at NCSM and how well it connects to my presentation for NCTM (tomorrow, 4/14) and it sparked me to write this post about building addition and multiplication fact fluency. I wrote a book a few years ago that included this addition fact chart and since then I also created one for multiplication: I share these with teachers when I do math professional development trainings, but I’ve never written about them on here. 4 Types of Addition Facts: Orange: Doubles Green: Make 10 Blue: 10 + something Purple: Adding Zero 4 Types of Multiplication Facts: Green: x2 Red: x10 Blue: x5 Purple: Properties (x1 and x0)
Fact Fluency Part 1: 4 Types of Addition & Multiplication Facts - The Recovering Traditionalist

The Recovering Traditionalist - Working to help teachers think outside the traditional way of doing, and teaching, mathematics.

Multiplication Bingo has long been one of my favorite games, and I recently introduced it to students who have been committing the multiplication facts to memory. (More about how the students are studying the multiplication facts appears at the end of the blog.) Also, several different versions of the game allow for varying and differentiating the experience, making it a good addition for the class Math Menu. First a Caveat about Understanding vs Memorization Years ago I had a conversation with Paul, a fourth grader. When I probed Paul’s thinking, I learned that he saw each multiplication fact as a separate piece of information to memorize. Introducing Multiplication Bingo: Version 1After talking with the students about playing Bingo, I told them I had a math version for them to play, Multiplication Bingo. I showed the class two 1–6 number cubes and explained, “I’m going to roll these two cubes and we’ll multiply the two numbers that come up. “Ready to play?” , some didn’t.

Easier Fibonacci Number puzzles
All these puzzles except one (which??) have the Fibonacci numbers as their answers. So now you have the puzzle and the answer - so what's left? Puzzles on this page have fairly straight-forward and simple explanations as to why their solution involves the Fibonacci numbers;. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987 ..More.. Fibonacci numbers and Brick Wall Patterns If we want to build a brick wall out of the usual size of brick which has a length twice as long as its height, and if our wall is to be two units tall, we can make our wall in a number of patterns, depending on how long we want it: There's just one wall pattern which is 1 unit wide - made by putting the brick on its end. Look at the number of patterns you have found for a wall of length 1, 2, 3, 4 and 5. Variation - use Dominoes A domino is formed from two squares. In mathematics, this is called tiling problem using dominoes and we wish to tile an area 2xn. Leonardo's Lane Boat Building Ones and Twos . .

Count On
Fibonacci Puzzles The Fibonacci Numbers are a sequence of numbers that start with 0 and 1. The rest of the series is determined by a simple rule: Add the latest two numbers to get the next one. Here are some puzzles where the answer is "The Fibonacci Numbers"! Puzzle 1: Brick Wall Patterns I have a supply of bricks, where each one is twice as long as it is wide. The answer depends on how long the path is going to be. Tip: Since ordinary dominoes are made up of two squares, they make idea "bricks" to experiment with for this puzzle. There is only one way to make a path 1 unit long, which is with 1 brick,but there are two patterns for a path of length 2 and three patterns for a path of length 3.How many brick patterns can you find for a path of length 4? Puzzle 2: Leaping up the stairs When I'm in a hurry, I leap up the stairs two at a time - until I get tired and go back to one at a time if it is a very long set of stairs. This gives a total of three patterns for three stairs.

Fibonacci Sequence
The Fibonacci Sequence is the series of numbers: The next number is found by adding up the two numbers before it. The 2 is found by adding the two numbers before it (1+1) The 3 is found by adding the two numbers before it (1+2), And the 5 is (2+3), and so on! Example: the next number in the sequence above is 21+34 = 55 It is that simple! Here is a longer list: Can you figure out the next few numbers? Makes A Spiral When we make squares with those widths, we get a nice spiral: Do you see how the squares fit neatly together? The Rule The Fibonacci Sequence can be written as a "Rule" (see Sequences and Series). First, the terms are numbered from 0 onwards like this: So term number 6 is called x6 (which equals 8). So we can write the rule: The Rule is xn = xn-1 + xn-2 where: xn is term number "n" xn-1 is the previous term (n-1) xn-2 is the term before that (n-2) Example: term 9 is calculated like this: Golden Ratio And here is a surprise. Using The Golden Ratio to Calculate Fibonacci Numbers Example: History

3 Practices to Promote Equity in the Classroom
I recently observed a classroom where students were presenting history projects to rows of silent and obedient classmates. Though the projects were diligently constructed, I couldn't focus on their content because I was distracted by two facts: only the teacher was asking questions, and he kept calling exclusively on girls to present. Ten minutes later, I walked into a completely different classroom where students rotated through the room presenting group projects to each other. The teacher instructed his class to "work to understand" the content through discussion, and every voice filled the room. These two experiences resurfaced a long-held question: What makes for an equitable classroom? Practice 1: Use Equity Sticks Equity sticks are a cheap and powerful way to check your biases at the door. Photo credit: Shane Safir Equity sticks keep students on their toes, mentally alert, and poised to contribute. Practice 2: Track Participation Data Who is participating the most? Think-Pair-Share
