Do you need a Trigonometry Help? Unable to work with sines and tans? Can’t get thetas in your head easily? Don’t worry, because we are to here to provide you the easiest trigonometry help. Do you know basic trigonometry? Basic trigonometry deals with basic concepts of triangles, their sides, their angles, and other basic trigonometric functions. Sine= perpendicular/ hypotenuseCos= base/ hypotenuseTan= perpendicular/ base The fascinating thing about the above-mentioned functions is that the moment you invert them, you get another trigonometric functions, as given below: Cosec= invert (sine)Sec=invert (cos)Cot=invert (tan Want to know other trigonometric functions? Some of other most commonly used trigonometric functionsare as given below: Cos (theta + 2 pi) = cos thetaSin (theta + 2 pi) = sin thetaSin (pi/2 – theta) = cos thetaCos (pi/2 – theta) = sin thetaSin^2 theta + Cos^2 theta = 1 Sin (-theta) = – sin thetaCos (- theta) = cos theta Keep tuning in trigonometry help to know more!
Loneliest Human Description and Lesson plan for the Base 10 Blocks Program It is believed that the Base 10 Blocks were developed by the Hungarian Mathematician Dr. Zoltan Paul Dienes. If you want to know more about himself, you can visit his web site. This page is specifically for teachers and describes a complete lesson plan on how to teach base 10 place value as well as basic arithmetic operations using this online version of the base 10 blocks manipulatives. Description of the Base 10 Blocks Program Check the detailed base 10 blocks program instructions to learn about rotate, break, glue, and place value mats! The blocks available in the program are the standard base 10 blocks used in many classrooms today and they are: This program is very simple to use. Two advantages that this program has over real physical blocks are, first, the ability to break the 10- and 100-blocks into the next smaller size and glue them back together. Uses of the Base 10 Blocks Program One of the best uses for this program is to present the concepts to the class. Addition Subtraction

Bar modelling- a powerful visual approach for introducing number topics Building on my recent post about a taxonomy for deep learning in maths, I have been trying to think a bit deeper myself about what each type of ‘deep learning link’ might look like. In particular, I have been researching and putting a lot of thought into what effective ‘visual models’ look like for the ‘key nodes’ I have previously identified as the most important foundation maths knowledge for students to master before starting their GCSE maths course. These are principally number topics. Last year I became aware of the Singapore Maths Bar Modelling approached have recently found the time to research it further. I bought some Singapore textbooks and read about the work of Dr Yeap Ban Har. This video, featuring Dr Ban Har shows an exemplification of the approach for a typical functional maths problem: Maths No Problem In primary education in Singapore, maths teachers follow a Concrete-Pictorial-Abstract (CPA) sequence when teaching maths topics. Next up, equivalent fractions:
