For example to generate random numbers, or probabilityĮxperiments. In edit mode, you can use the probability spinner however you want. The slider max value is 12, but if you click on the number you can enter your own manually, although in practiceĥ0 is about the maximum number that visually fit on the spinner. To change the number of sides for the spinners make sure you have selected Initially six sided hexagon spinners are shown which are useful Number selector in the top right hand corner. You can change the number of spinners shown by clicking the Produce a result using addition, subtraction, multiplication and division. With the built in activities you can practice BODMAS, algebraic substitution or challenge students to find the rule to These can be used as random number generators This page links to a set of activities created by John Rowe – titles certainly look good and seem to cover some higher level maths ideas (like derivatives/differentiation inc.The spinner activity can display up to four spinners.This one links to a Google sheet of John Orr’s tasks – many which are not searchable in Desmos.Here’s a page that links to Andrew Stadel’s database of desmos activities that he’s created (estimation 180 guy).This is a clothesline activity on desmos exploring fractions, decimals, percentages….‘ Sketchy dilations‘ introduces students to dilations/ratio through experimenting with “sketching machines” that allow them to adjust various parts of a drawing to see the effect on the pre-image.A ‘repair shop’ activity where students compare linear and exponential growth in the context of daily payments.Categorical Data: Frequency and relative frequency uses data from the titanic and a good ‘story’ development in the activity.One for focusing on translation of standard y=x^2 parabola.Puzzling it out helps students solve angle puzzles to apply what they’ve learned about angle relationships and to informally learn the Triangle Sum theorem.Chance experiments I used as a good introduction to probability with year 8’s (designing spinners, using language etc.).Rogue planes is about changing the cartesian plane, rather than the line, for linear equations.Another modelling activity/lesson (not desmos) is Robert k’s one on math modelling predicting pregnancy! (includes a link in the opening paragraph to other activities around spies etc too!).Here is one on modelling with 400m times from Olympics.This one explores the idea of linear equations and a card sort on whether equations are parallel or perpendicular to a given line too.Activity on using a number line to help with the concept of multiplying integers.And another one on equations, assessing understanding of y = mx + c.This one helps with writing linear equations from a graph.Here is an introduction to domain and range.In ‘ zero and negative exponents‘ students use Desmos “Sketch” to generate patterns to explore zero as an exponent and negative exponents – something students have often struggled with (tag: indices, powers too).The ‘ chormagons‘ activity just looks like an interesting exploration.NB> since order of operations mentioned above, here’s a pic to show on the topic! Another puzzle on desmos is the Twin Puzzles, which is a good order of operations task (googling desmos and puzzle might return more ideas too…).Wolves and sheep is just a fun puzzle, not necessarily curriculum linked.Get close to me is a rounding activity (that came from using clothesline maths too).MAGIC! Showing how multi-step equations can be used to work out someone’s chosen ‘mystery’ number.They have one too on periodic functions and one on quadratic relations (Mr Orr’s site covering all three and some explanation is here). Talkers and drawers is an informal pair activity on linear relationships.Collecting like terms – as it says…begins with character/disney type matchup for practice, then a cardsort on collecting like terms ( note the teacher dashboard when you look at results shows you if it’s right or not).Home run kings – Using data to make predictions, using statistics / graphs. There formula (A=lw) is not mentioned in this lesson and can be brought up in a class discussion Area of rectangles – Students learn how to find the area of a rectangle given a grid and side lengths.A good one for showing to others who might be interested… Here is another page a teacher compiled when they were running PD’s introducing people to Desmos. List of activities sourced (mostly through twitter), that (I fear!) may not appear in regular Desmos search engine…įirst up though is this fantastic intro to showcase what Activity Builder can do in desmos.
