5 Ways to Make Fact Fluency Fun - One Stop Teacher Shop As teachers, we know how important it is for students to know their math facts fluently. Without this skill, it is difficult for them to learn higher level math concepts. The best way for student to learn these facts is to practice, practice, and practice. Unfortunately, students don’t always want to do what is best for them. Free Math Textbooks Free textbooks (aka open textbooks) written by knowledgable scholars are a relatively new phenomenon. Below, find a meta list of Free Math Textbooks, part of our larger collection 200 Free Textbooks: A Meta Collection. Also see our online collection, 1200 Free Online Courses from Top Universities.

Mathematics -    THE POSITIVE ENGAGEMENT PROJECT Concept Learning Bricks are foundational vocabulary terms and concepts, designed for multi-sensory learners, that students need to master before they can apply the actual concepts to other areas. Each Concept Learning Brick is organized with a question, answer, physical gesture movement, concept examples, and picture to represent the academic term. The image on the card, associated memory gesture, and vocabulary definition allow students to see, hear, say, and do so much more with these crucial terms in a way that is fun and engaging. Over 220 concepts are available! Acing Math (One Deck At A Time!) is a collection of math games ranging from Kindergarten to the upper elementary grades, using only an ordinary deck of playing cards.

Where The Wild Fractions Are: The Power Of A Bedtime (Math) Story : NPR Ed Parents who are uneasy about their own math skills often worry about how best to teach the subject to their kids. Well ... there's an app for that. Tons of them, in fact. Cone Construction Calculator A cone is constructed by taking a circle sector of radius L and angle θ and joining the two straight edges together. And any cone without a closed base can be formed back into a circle sector by cutting a straight line from the nape to the base and flattening the resulting figure. If you are given L and θ, you can plug these values into equations to find the height (H) and base radius (R) of the corresponding cone. Likewise, if you are given H and R, you can plug these values into equations to find L and θ. These formulas are explained below the diagrams. You can also use the conventient calculator on the left to find H and R or L and θ.

Math Teaching Strategies: The Language of Math One of the best math teaching strategies is teaching math concepts through the use of math word walls. It really is all about the words, I have discovered, and teaching the language of math is critical to teaching math concepts and procedures. I honestly don't think I could ever teach math without a word wall ! We have time every day for reviewing the words, and it is the most helpful strategy I know for teaching vitally important math terminology. Wall words should also be used to support reading since reading is the most important skill children learn in school. Favorite Math Word Wall Activities

Numbers – Visualizations I have several references in various places on this blog to some great visualizations. Time to put them all together! Jeffrey Ventrella’s Composite Number Tree From Jeffrey Ventrella this wonderful Composite Number Tree – I have used this successfully with many students. It makes a great starter. Students can work out themselves how the tree is being formed and comment on any patterns they notice. Arc Length part of the circumference First i'll cover some arc definitions, alternatively you can jump straight to how to find arc length. Arc definition: A section of the circumference We would call this arc AB, after it's endpoints
