Murderous Maths: The Calendar Trick. This trick makes you look like you've got the most awesome mental power.
All you need is a calendar which has the dates lined up under the days of the week, so the numbers are arranged something like this: The "9 number" trick Ask a friend to draw a 3x3 box around ANY nine of the numbers on the calendar. Almost immediately you can say what the nine numbers all add up to! See how long it takes your friend to check the answer on a calculator. For instance, let's say the red numbers are chosen. They add up to 198. THE SECRET: All you do is look at the number in the middle and multiply it by 9.
In this case the middle number is 22 and 22 x 9 = 198. HANDY TIP: To multiply by 9 quickly, just multiply by 10 then subtract your number. 14 Virtual Tools for the Math Classroom. More and more classrooms are gaining access to technology that can be used with students.

Solving KenKen puzzles does all three. After getting hooked on solving them myself, I explored their classroom potential, and I’ve been pleased with the results. At first glance, KenKen puzzles look like Suduko puzzles—you fill a grid with numbers. Both are logic puzzles, but KenKen puzzles have the instructional benefit of providing practice with basic facts. Plus Ken Ken puzzles are ideal for differentiating instruction. KenKen Puzzles Come in Different SizesIn KenKen puzzles, the numbers you’re allowed to write to fill the grid depend on the size of the grid.

Graphing Stories - The Math in Short Videos. Progressions Documents for for Mathematics. Interactive Fraction Wall explore Fractions Percentages and Decimals. Fraction walls are a great way to teach about fractions and in particular equivalent fractions. In a fraction wall each row or layer of the wall represents one whole number. The layers are divided into a number of bricks and hence each brick represents a fraction whose denominator is equal to the number of bricks in that layer. Each brick can be turned on or off by clicking it. This wall also allows the display of decimal and percentage values. To the right of the wall are boxes which can be hidden, the value of each box is fraction of the wall that has been turned on. CCSS-M = Common Core Math. Student Growth Across Grade Levels with New Common Core Math Videos. As a 1st grade math teacher, I never thought I was teaching the same skills as high school math teachers.
But as I’ve gotten to know the Common Core State Standards, the math practice standards have shown me that effective math teaching looks remarkably similar across grade levels. Through the practice standards, K-12 students will develop skills around problem solving, reasoning and proof, connections, representation, and communication. Regardless of the grade level, focusing on these standards helps students feel comfortable explaining their thought processes, learning from others, and building conceptual understanding.
Teaching Channel recently partnered with the American Federation of Teachers to create a series of videos that show how two of the Common Core Math Practice Standards progress throughout the grades. While the goal is for the math practice standards to be used K-12, we know that nothing looks exactly the same across grade levels.
