Number Pieces by The Math Learning Center Overview Number Pieces helps students develop a deeper understanding of place value while building their computation skills with multi-digit numbers. Students can: Use number pieces to represent multi-digit numbers, regroup, add, subtract, multiply, and divide.

Plane developments of geometric bodies (1): Nets of prisms A right prism is a polyhedron that has two congruents pararel polygonal faces (bases of the prism) and with all remaining faces are rectangles. The main interest of this page is to see how a right prism can be developed into a plane net. There is a platonic solid that is a prism, the cube. This is a cube net:

Morning Math Routines Growing Number Line Each day a student adds one post-it to the growing number line. In this case, a kindergarten student wrote the number and posted it. The student then leads the class in counting the days they have been in school. Many teachers now arrange this growing number line into a growing hundred board configuration, varying the color for each group of ten. Fractions by The Math Learning Center How To Use Fractions Working with Fraction Bars and Circles More Toolbar Items Overview Fractions lets students use a bar or circle to represent, compare, and perform operations with fractions with denominators from 1 to 100. Choose the fraction model and number of equal parts.

Number Frames Overview Number Frames help students structure numbers to five, ten, twenty, and one hundred. Students use the frames to count, represent, compare, and compute with numbers in a particular range. The frames help students see quantities as equal groups of other quantities and in relation to benchmark quantities. This helps primary students move away from one-by-one counting toward more efficient ways of counting and computing. Multi Digit Multiplication Strategies - Mr Elementary Math Look at the problem below and think about how your students would respond to the two questions: What is the value of the 2?Why should we place a 0 in this space? If your students answer the questions by saying, “the 2 is worth 2,” or “I placed the 0 in that area because I was always told to move it down,” consider the idea that the student(s) do not fully understand the concept of multiplying multi digit numbers. According to John Van De Walle, “For multiplication, the ability to break numbers apart in flexible ways is even more important than in addition or subtraction.

Waterman Polyhedra Play with the controls! Use the "Sequence" slider to step through the series of polyhedra. Click the "Colors" button. If you have red-blue 3D glasses, change the "Stereo Mode" to "Anaglyph". If you have a ColorCode ViewerTM (see below), change the "Stereo Mode" to "ColorCode". Further instructions are below the applet. Symmetry in Nature By Angel Abney, Andy Tyminski, and Pawel Nazarewicz Mathematics is all around us. As we discover more and more about our environment and our surroundings we see that nature can be described mathematically. The beauty of a flower, the majesty of a tree, even the rocks upon which we walk can exhibit nature's sense of symmetry. Although there are other examples to be found in crystallography or even at a microscopic level of nature, we have chosen representations within objects in our field of view that exhibit many different types of symmetry.

Money Pieces by The Math Learning Center How To Use Money Pieces Working with Pieces Working with Shades Shades with illustrations can be used to pose problems with unknown quantities of money The Elementary Math Maniac: A Fun Free Tool for Practicing Counting If you have ever been in a K-2 math class, you know how important counting is. I recently posted some of my favorite you tube videos for practicing counting, my favorite counting books, and have written a seven part series on estimating and counting routines that I use in my classroom. I have also written about interventions I use to help kids learn to count. Today I want to share with you a great tool to use on your computer, projector or SMART board to help your students practice many important counting skills Flip Counter This is a demonstration tool provided by ict games.

The life and numbers of Fibonacci Fibonacci is one of the most famous names in mathematics. This would come as a surprise to Leonardo Pisano, the mathematician we now know by that name. And he might have been equally surprised that he has been immortalised in the famous sequence – 0, 1, 1, 2, 3, 5, 8, 13, ... – rather than for what is considered his far greater mathematical achievement – helping to popularise our modern number system in the Latin-speaking world. The Roman Empire left Europe with the Roman numeral system which we still see, amongst other places, in the copyright notices after films and TV programmes (2013 is MMXIII).
