T - At the moment, there isn't a way to give feedback to students through the activity, but it is on our list! Is it possible to have students choose answers from a list?
Thanks, Noirin Foy nfoy lasdschools. I used this Activity Builder last semester and I remember being able to see the student's progress. I used it again today and it was not showing any of the progress of the students.
Is this a new feature or are there settings I need to adjust? I use this as my warmup activity and it helps me to know when students are just about wrapped up with the problems. I would love to be able to send my students the answer key once they have completed the activity as well!
Is there a way to allow the students to see which of their answers are incorrect in card sort? They can see that they have answers that are wrong, but I would like for them to be able to see the ones that are wrong so that they may correct those.
Have more questions? Submit a request. Please ignore my question re the inequality, I figured it out. Is there a way to allow students to see the answer key once they have finished the activity?
Powered by Zendesk.Like many of my generation, I grew up coming home from school each day turning my television set to channel three and firing up my Nintendo to play the newest video game. Video games challenged me to solve problems, discover patterns and react to a variety of situations.
The visible representations of movement and action combined with a level of intellectual undertaking would keep me occupied for hours. Teaching in this way removes many of the barriers found in traditional mathematics instruction. So then, how can we use video games to transform classroom mathematics? Mathematics should be presented in a way that enables students to connect math concepts to visual action.
Everyone can see an action and interpret it. When someone runs or jumps, it can be understood in any language. Video games have the power to show mathematical concepts in the form of a specified type of action.
Standard problem: Three dimensions of a cube are reduced to one-half their original length. If its original volume was cubic units, what is its new volume? This a procedural based approach that only works with cubes.
So, what happened? Almost every student can see or tell you that the shape was cut in half. Students can develop a conceptual understanding of change in dimension when mathematics are presented through this type of action. In this example students are not constrained to formulas or algebraic symbols or even numbers. It is about constructing mathematical knowledge and understanding that can be applied to any type of situation. I posed this question to a group of seventh grade students. I showed them a video of Mario smashing the block in half and asked them what happened.
Every one of them had the understanding that if the volume of a shape is cut in half only one dimension is changed because they could see it and there were no numbers or symbols getting in the way of processing the action.
Some sample student responses:. It is in this way that visual representations through the action in video games allows conceptual understanding and personal meaning to take root. Desmos also has the ability to create situations for students in which they can easily generate their own data.
When students have a level of engagement with or attachment to data, the situation in which the math is presented takes on a different level of meaning.
Desmos has a variety of activities in which students have such an opportunity. Students play through the boxing game and generate points in each level by fighting various boxers.Statistical functions require an argument in order to be used. Using table headers or lists are possibilities. In these cases, "a" is used to represent a list or table header previously defined by the user in the calculator.
Could you implement the two argument arctangent atan2 function as well? It's a lot more useful than the standard arctangent function, and I'm getting tired of having to redefine it every project. Would be great if there were a "Fraction" function converts answer to reduced fraction if possible Karen, the "sign x " function returns 1 for positive values, -1 for negative values, and 0 for 0. For example, round As for the suggestion above, it'd be best if the round function could work for both one argument and two arguments when the second argument isn't specified, it should be 0 decimals.

I only have this problem when restricting domain AND range. How can I fix this? Hi, I'd like to plot a domain indexed by a parameter k that takes values -2,-1,0,1,2all at the sametime. How can I do that without explicitly stating the five domains in separate lines.
Can you limit a polar equation? How can I do that? Does desmos limit the domain? I would like to plot this function over a larger domain than [0,12pi].
Ahedman - Polar graphs are automatically set to a domain of [0, 12pi]. It's possible to restrict the domain to a smaller interval but not to make it larger. That is a supremely unfortunate. I strongly recommend that you increase both the upper and lower bound in future versions. There are a number of interesting functions I would like to show my students that your program is now useless for.
Is there any way for me to set the domain to fulfill those requirements? For example, is there any way I could create a line, and then effectively erase intermittent segments of it by adding multiple domain restrictions using "or"? To use an "and", you need to use a pair of brackets for each restriction.
The fucntion below should give you what you're looking for. I tried to limit the range r value on a polar equation inequality, but it wouldn't let me. It said polar equations must be linear in r. I don't see why r can't be limited under these conditions, is this just something Desmos doesn't let you do?
Can you check my circle, at kirby's legs, there is still some lingering lines after stating the restrictions.Post a comment. Desmos Activities. Below are a list of custom Desmos activities.
They range in grade from They are in chronological order from when they were made so you may just want to search the page with keywords.
Activity Builder: Overview
Let me know if you have any questions or see any issues. In this activity the idea is that to help students develop tools for fraction subtraction, one way to do that without just telling them the rules is to use a progression of successively more and more complex problems. In this activity, the problems become more and more complex with practice along the way and then finishes with a Challenge Creator so students can create their own fraction subtraction problem.
This is intended to be a mix of investigation, consolidation and practice and likely won't be done in a single period. In this investigation, students can get practice using sine law while investigating the nature of the ambiguous case. Once they are done, then students can create their own problems for each other to solve using the Challenge Creator at the end.
Because we ask to write down their solutions, this would be best done with iPads or touchscreen laptops. Below are a list of over 20 Desmos Activities that investigate basic geometric theorems that span grade here in Ontario some of which can be seen below.
Though these are very basic activities with some dynamic features and could be done via paper and pencil, ultimately the power in using them is in exploiting the features of the teacher dashboard to show student work and pace the class.
This is a Desmos version of a Websketch I made years ago. In this sketch students explore creating Escher like tessellations by dragging any of the red points to change all of the shapes. So this is bit of an experiment. The idea here is that students would practice by working out the answers to the angles using the Desmos Sketch feature ideally this works best on a touch screen device and then they can check their answer immediately by measuring the angles on the next slide using Desmos geometry.
It doesn't really exploit a lot of Desmos features but still could give you some insight into where students are having difficulties. In this activity students are introduced to the concept of the two dimensional vector equation. At the end of the activity there are two slides with randomly generated practice problems. This activity assumes students are familiar with coordinate vector notation. This is meant to be a consolidation task to be done after the class has been introduced to histograms and the distinction between continuous and discrete data.
It starts with two card sorts then there are a few slides to get some idea of the connection of average. Email This BlogThis! No comments:.
