Online Triangle Solver

TrianCal - Open in Google Chrome. (Triangles online calculator developed by Jesus S.) I propose this free online calculator triangles without advertising to help students with geometry, does not perform the duties, because their calculations formulas are not displayed. It is designed in a didactic way to check and view the realized duties. TrianCal is online calculator triangles that works with any combination of values including sides, heights, angles, the area, perimeter or type of any triangle, calculating it with the minimum possible value (typically three). Other functions: - Draw the triangle (s) with GeoGebra. - Set the range of values in each element. - Chande name of vertex - The type of angle. - The type of triangle by its angles and sides. - Selection of language (English or Spanish). - Select the angle type [degrees (°), radians, degrees, minutes and seconds (° ' ") or degrees and minutes (° ')]. - Number of decimal places shown in the results (0-15). - You can use the arrow keys and the Tab key to navigate through the settings. - Drop-down menu to select the values comfortably. - Create a link (URL) to the current triangle. - An icon mail to communicate with the author. NOTE: You must use the Google Chrome browser to display correctly TrianCal. Examples of possible combinations: - The area, perimeter and other data (side, height or angle), if the outside equilateral triangle would not need the third data. - 2 angles and other data (if the value of the other data is not put aside the value of "a" at the time of drawing the triangle is 10).

Negative Numbers

Negative Numbers

FREE for new buyers – Enter code SEPTEMBER-SAVER at checkout. A range of activities to resource differentiated negative numbers lessons at Key Stage 2 (KS2) and some early KS3. Includes 3 fun Hidden Word / Spot the Mistake Puzzles (and solutions), a 30-card Loop Game / Dominoes Set and 16 Word Problems Cards (8 multi-step and 8 more simple). PUZZLES An engaging alternative to worksheets, these Numeracy puzzles make ideal starter, early finisher or homework activities. There’s one on increasing and decreasing temperature (Celsius), one for simple subtraction calculations with mostly negative number answers and a more challenging puzzle featuring addition and subtraction of negative and positive integers. Puzzles can be completed individually or in pairs / groups. Similar to codebreaker puzzles, a maths-related word is revealed after completing calculations. Each puzzle contains a grid. Within each box is a calculation and a letter. Pupils circle any boxes containing errors. Then they assemble letters from remaining boxes to reveal a maths word. There's a further challenge question / task at the bottom of the page linked to the word. Pupils often forget or avoid checking their work for errors so it’s great to get them carefully checking in these puzzles. Spotting common errors may help them remember to check their own work and help them avoid common errors themselves. LOOP CARDS / DOMINOES Fun group / whole class activity to consolidate adding and subtracting negative numbers, using a range of phrases ('reduce by', 'increase', 'difference between' etc). It forms a continuous loop so start anywhere. WORD PROBLEM CARDS 8 Multi-Step Word Problem Cards and 8 more simple. Solutions can be printed back to back with question side for student self-checking or can be printed and made into separate cards if required. Consolidates understanding of negative numbers in the contexts of temperature (degrees Celsius), money / bank accounts and points in a sporting league. Work well as early finisher challenges. Separate pounds and dollars versions included. My Hidden Word and Crossnumber Puzzle Packs have been especially popular.

What can you power? Lesson plan

What can you power? Lesson plan

How much energy can you generate by exercising? In this activity students discover ‘people power’. They investigate the fact that people generate power when they exercise. They calculate their own power output and compare it to that of a professional athlete.
